1993 Grand Prix motorcycle racing season
The 1993 Grand Prix motorcycle racing season was the 45th F. I. M. Road Racing World Championship season. Kevin Schwantz won the 1993 world championship in a season marred by the tragic end to his rival Wayne Rainey's career. Schwantz started the season with four wins by the midpoint of the season. With three races remaining, Rainey had battled back to take the championship points lead while Schwantz nursed a wrist injury. At the Italian Grand Prix, Rainey was pulling away when he fell, he would never walk again. Rainey's accident marked the end of an era of American domination in Grand Prix racing. Newcomers Daryl Beattie and Alex Barros took their first wins while Mick Doohan struggled to recover from his serious leg injuries. Freddie Spencer crashed in two of the first three rounds. Honda entered factory test rider Shinichi Itoh on a third bike with development parts, rumored to include electronic fuel injection, as he was noticeably faster in a straight line that the other Honda riders; when Itoh broke the 200 mph barrier at Hockenheim, it gave credence to these rumors.
All three bikes gained the injection system at the same time A new star emerged on the 250 scene with Tetsuya Harada taking the crown in a tight battle with Loris Capirossi. German privateer, Dirk Raudies won the 125 crown with 9 victories on a Honda; the 1993 season marks the last time a rider is allowed to compete in two different classes at the same race. The following Grands Prix were scheduled to take place in 1993: The Australian Grand Prix replaced the Japanese Grand Prix with hosting the opening round Grand Prix; the Hungarian and Brazilian Grand Prix were taken off the calendar after Bernie Ecclestone focused his interest on Formula 1 again. The Austrian, San Marino, Czech Republic and United States Grand Prix returned on the calendar after the shift of interest to Formula 1 by Bernie Ecclestone; the FIM Grand Prix was added to the calendar as a one-off Grand Prix to replace the South African Grand Prix.

Honda Motor Company, Ltd. is a Japanese public multinational conglomerate corporation known as a manufacturer of automobiles, aircraft and power equipment. Honda has been the world's largest motorcycle manufacturer since 1959, as well as the world's largest manufacturer of internal combustion engines measured by volume, producing more than 14 million internal combustion engines each year. Honda became the second-largest Japanese automobile manufacturer in 2001. Honda was the eighth largest automobile manufacturer in the world in 2015. Honda was the first Japanese automobile manufacturer to release a dedicated luxury brand, Acura, in 1986. Aside from their core automobile and motorcycle businesses, Honda manufactures garden equipment, marine engines, personal watercraft and power generators, other products. Since 1986, Honda has been involved with artificial intelligence/robotics research and released their ASIMO robot in 2000, they have ventured into aerospace with the establishment of GE Honda Aero Engines in 2004 and the Honda HA-420 HondaJet, which began production in 2012.
Honda has three joint-ventures in China. In 2013, Honda invested about 5.7 % of its revenues in development. In 2013, Honda became the first Japanese automaker to be a net exporter from the United States, exporting 108,705 Honda and Acura models, while importing only 88,357. Throughout his life, Honda's founder, Soichiro Honda, had an interest in automobiles, he worked as a mechanic at the Art Shokai garage, where he entered them in races. In 1937, with financing from his acquaintance Kato Shichirō, Honda founded Tōkai Seiki to make piston rings working out of the Art Shokai garage. After initial failures, Tōkai Seiki won a contract to supply piston rings to Toyota, but lost the contract due to the poor quality of their products. After attending engineering school without graduating, visiting factories around Japan to better understand Toyota's quality control processes, by 1941 Honda was able to mass-produce piston rings acceptable to Toyota, using an automated process that could employ unskilled wartime laborers.
Tōkai Seiki was placed under control of the Ministry of Commerce and Industry at the start of World War II, Soichiro Honda was demoted from president to senior managing director after Toyota took a 40% stake in the company. Honda aided the war effort by assisting other companies in automating the production of military aircraft propellers; the relationships Honda cultivated with personnel at Toyota, Nakajima Aircraft Company and the Imperial Japanese Navy would be instrumental in the postwar period. A US B-29 bomber attack destroyed Tōkai Seiki's Yamashita plant in 1944, the Itawa plant collapsed in 13 January 1945 Mikawa earthquake. Soichiro Honda sold the salvageable remains of the company to Toyota after the war for ¥450,000, used the proceeds to found the Honda Technical Research Institute in October 1946. With a staff of 12 men working in a 16 m2 shack, they built and sold improvised motorized bicycles, using a supply of 500 two-stroke 50 cc Tohatsu war surplus radio generator engines.
When the engines ran out, Honda began building their own copy of the Tohatsu engine, supplying these to customers to attach to their bicycles. This was the Honda A-Type, nicknamed the Bata Bata for the sound. In 1949, the Honda Technical Research Institute was liquidated for ¥1,000,000, or about US$5,000 today. At about the same time Honda hired engineer Kihachiro Kawashima, Takeo Fujisawa who provided indispensable business and marketing expertise to complement Soichiro Honda's technical bent; the close partnership between Soichiro Honda and Fujisawa lasted until they stepped down together in October 1973. The first complete motorcycle, with both the frame and engine made by Honda, was the 1949 D-Type, the first Honda to go by the name Dream. Honda Motor Company grew in a short time to become the world's largest manufacturer of motorcycles by 1964; the first production automobile from Honda was the T360 mini pick-up truck, which went on sale in August 1963. Powered by a small 356-cc straight-4 gasoline engine, it was classified under the cheaper Kei car tax bracket.
The first production car from Honda was the S500 sports car, which followed the T360 into production in October 1963. Its chain-driven rear wheels pointed to Honda's motorcycle origins. Over the next few decades, Honda worked to expand its product line and expanded operations and exports to numerous countries around the world. In 1986, Honda introduced the successful Acura brand to the American market in an attempt to gain ground in the luxury vehicle market; the year 1991 saw the introduction of the Honda NSX supercar, the first all-aluminum monocoque vehicle that incorporated a mid-engine V6 with variable-valve timing. CEO Tadashi Kume was succeeded by Nobuhiko Kawamoto in 1990. Kawamoto was selected over Shoichiro Irimajiri, who oversaw the successful establishment of Honda of America Manufacturing, Inc. in Marysville, Ohio. Irimajiri and Kawamoto shared a friendly rivalry within Honda. Following the death of Soichiro Honda and the departure of Irimajiri, Honda found itself being outpaced in product development by other Japanese automakers and was caught off-guard by the truck and sport utility vehicle boom of the 1990s, all which took a toll on the profitability of the company.
Japanese media reported in 1992 and 1993 that Honda was at serious risk of an unwanted and hostile takeov
Donington Park is a motorsport circuit located near Castle Donington in Leicestershire, England. The circuit business is now owned by Jonathan Palmer's MotorSport Vision organisation, the surrounding Donington Park Estate is under lease by MotorSport Vision until 2038. Part of the Donington Hall estate, it was created as a racing circuit during the period between the First and Second World Wars when the German Silver Arrows were battling for the European Championship. Used as a military vehicle storage depot during the Second World War, it fell into disrepair until bought by local construction entrepreneur Tom Wheatcroft. Revived under his ownership in the 1970s, it hosted a single Formula One race, but became the favoured home of the British round of the MotoGP motorcycling championship. Leased by Donington Ventures Leisure Ltd in 2007 the hope that Formula One racing could return to the track, the incomplete venture failed to raise sufficient financial backing during the aftermath of the 2008 global financial crisis.
DVLL lost the rights to the British rounds of both Formula 1 and MotoGP, in its bankruptcy returned the track to the Wheatcroft family in December 2009. Under Wheatcroft's ownership, the venue underwent significant work, with the track restored to use in 2010, before major upgrades in the following five years. At the end of 2010, it was announced that Donington would become home to an annual historic motorsport event, the Donington Historic Festival, with new events being added. Since 2010, significant investment across the venue has seen major improvements made to its infrastructure, while the circuit has become a regular fixture for top class motorcycling in the form of the Superbike World Championship. In January 2017, the circuit business and a long term lease on the estate was purchased by MotorSport Vision, with the purchase cleared by authorities in August of the same year. Significant investment has seen facilities at the venue brought up to modern standards, with a new restaurant, toilet blocks, large new grandstand and new circuit offices, as well as other detail changes.
As well as improving the infrastructure, MSV has made additions to the race calendar, with additional major events planned for 2019 including extra rounds of the British Superbike Championship and British GT. Donington Park motor racing circuit was the first permanent park circuit in England, which ended the race circuit monopoly that Brooklands had held since 1907. Fred Craner was a former motorcycle rider who had taken part in seven Isle of Man TT races, was by 1931 a Derby garage owner and secretary of the Derby & District Motor Club. Craner approached the owner of the Donington Hall estate, Alderman John Gillies Shields JP, to use the extensive roads on his land for racing; the original track was 2 mile 327 yd in length, based on normal width unsealed estate roads. The first motor cycle race took place on Whit Monday, 1931. For 1933 Craner obtained permission to build a permanent track, with the original layout widened and sealed at a cost of £12,000; the first car race was followed by three car meetings further that year.
The first Donington Park Trophy race was held on 7 October 1933, the 20-lap invitation event was won by the Earl Howe in a Bugatti Type 51. In 1935 the first 300-mile Donington Grand Prix was won by Richard "Mad Jack" Shuttleworth in an Alfa Romeo P3. In the 1937 Donington Grand Prix and 1938 Donington Grand Prix, the race winners were Bernd Rosemeyer and Tazio Nuvolari, both in Auto Union'Silver Arrows.' The circuit at Donington Park was closed in 1939 due to World War II, when it was requisitioned by the Ministry of Defence and was converted into a military vehicle depot. In 1971 the circuit was bought by business man and car collector Tom Wheatcroft, who funded the rebuilding of the track. Wheatcroft moved his collection to the circuit, in a museum now known as the Donington Grand Prix Exhibition which opened in 1973, has the largest collection of Grand Prix cars in the world; the motor racing circuit re-opened for cars on 28 May 1977, as per the original pre-war opening, the first post-war meeting was for motorcycles.
The first postwar car race meeting was organised by the Nottingham Sports Car Club, sponsored by local Lotus dealers, J A Else of Codnor. That first car meeting nearly didn't happen, as the local ramblers tried to assert their rights to retain access to footpaths at the eleventh hour; the meeting went ahead as a "Motor Trial", a legal loophole that curtailed the use of single seater racing cars for that opening meeting. The NSCC continued to run race meetings at Donington until the Donington Racing Club was formed and a licence to run race meetings obtained; the Melbourne Loop was built in 1985 to increase the lap distance to 2.5 miles and allow the track to host Grand Prix motorcycle races – at 1.957 miles without the loop, the circuit was deemed too short. This shorter layout remains as the National circuit, used for most non-Grand Prix events. In recent times Donington has held meetings of MotoGP, the British Touring Car Championship and British Superbike Championship, as well as the 1993 European Grand Prix.
Other events taking place at the track include a 1000 km endurance race for the Le Mans Series in 2006, the World Series by Renault and the Great and British Motorsport Festival. On 26 August 2007, the circuit hosted the British Motocross Grand Prix, with a purpose-built motocross circuit constructed on the infield of the road circuit. In 2007, Wheatcroft via the holding company Wheatcroft & Son Ltd, sold a 150-year lease on the land on which the track and museum are located to Donington Ventures Leisure Ltd. In July 2008, it was announced that DVLL had won the rights to the British Gra
Mika Kallio is a Finnish Grand Prix motorcycle racer. He debuted in the 125cc World Championship with the Finnish rookie team Ajo Motorsport in 2001 and was awarded the "Rookie of the Year" in 2002. After moving to Red Bull KTM during the 2003 season, he finished runner-up in the class in 2005 and 2006. In his first year with KTM in the 250cc class, Kallio finished seventh. In 2008, he led the championship throughout the first half of the season having to settle for third place. For the 2009 season, he moved to the MotoGP class, racing on a Ducati Desmosedici GP9 for Ducati's satellite team Pramac Racing where he finished 15th in his first season in the top class and obtained the "Rookie of the Year" award; however 2010 was less successful, struggling with injury and lack of confidence, resulting in a lowly 17th. Kallio looked to rediscover his form, competing in the Moto2 World Championship for the Marc VDS Racing Team over the next four seasons, riding a Suter in 2011, but would end the first season in 16th.
A switch to the Kalex frame from 2012 led to marked improvement in results over the next few seasons. The Finn finished 2012 in 6th place, improved to 4th overall in 2013, mounted a strong title challenge throughout 2014 having to settle for runners up position. 2015 saw a switch to the Italtrans team, disappointing results led to a mid season switch to the QMMF Racing Team for the remaining five rounds. In 2016, the Finn took time out from full-time racing, returning to KTM, to become their lead test rider for the then-new MotoGP project, commencing in 2017. Kallio suffered a serious knee injury at the 2018 German motorcycle Grand Prix. Born in Valkeakoski, Kallio started racing in 1997 and won the Finnish championship in road racing with further success in 1999 and 2000. During 2000, he became the Nordic champion after finishing second in the previous year. While Kallio pursued his road racing goals, the Finn has scored plenty of success in ice racing back home in Finland, having achieved the Finnish motorcycle ice racing championship in 2000, 2004 and 2005 in the 125cc class.
At 500cc level, Kallio won the title in 2004 and 2006. Kallio made his debut in the 125cc World Championship as a wildcard rider at the 2001 German Grand Prix. Continuing with Ajo Motorsport and the Honda RS125R for a full season in 2002, he finished as the Rookie of the Year. Halfway through the 2003 season, Kallio switched to KTM's factory team, he took his career-best fourth place in Czech Republic. The highlight of 2003 was a second place at Sepang behind Dani Pedrosa. After a 2004 season filled with bike reliability issues, Kallio took his first championship pole position and victory at the second round of the 2005 season at Estoril, he went on to take seven more poles and three more wins and lost the world title by just five points to Thomas Lüthi. He lost five points at the fourth-last Grand Prix in Qatar when his KTM teammate, Gábor Talmácsi, pulled out from behind the slipstream and passed him on the last few metres of the race to take the win by 0.017 seconds. Kallio had started from pole position and led every lap of the race and was not pushing on the home straight anymore, as Talmácsi had been ordered to stay back by the team because he was not a title contender.
Talmácsi was fired after the season finale at Valencia. In 2006, Kallio was again a challenger for the 125 cc title. Although he produced his best season to date, the young Finn was outshone by Spain's Álvaro Bautista and while he tried to hang onto the Spaniard, he was forced to settle for the runner-up spot once again, although he did finish a full 65 points ahead of the third position. Kallio scored four pole positions and 11 podiums during the 2006 campaign. At the end of the year, viewers of the Finnish motorsport television series Ruutulippu voted Kallio the Finnish Motorsportsman of the Year for the second year running, he collected 33.1% of all votes and pipped enduro world champion Samuli Aro, WRC runner-up Marcus Grönholm and F1 star Kimi Räikkönen. For the 2007 season, Kallio moved up to KTM's squad in the 250cc category alongside Japan's Hiroshi Aoyama. After a difficult start to the season with mechanical woes at Qatar and Spain, Kallio would be fighting around the top six positions.
The turning point of the season would be at Germany, where Kallio took his debut pole position and podium finish in the class for come home in 2nd behind teammate Aoyama to cap a fine 1–2 for KTM. A third place followed at the Czech Republic, although a nasty highside at San Marino, more mechanical problems at Portugal were to slow his progress; however the Finn would capture his first 250cc class victory at the rain-soaked Japanese race, added to his tally at the final round in Valencia, fending off Alex de Angelis on the final lap. He ended the season with two pole positions, two wins, four podiums and two fastest laps to place him seventh in the standings with 157 points. Kallio remained at KTM for 2008. A strong start to the season saw a third place at the season opener under the floodlights of Qatar. A fortunate win at Jerez, Spain after title rivals Álvaro Bautista and Marco Simoncelli crashed out together on the final lap. Another solid third place at Portugal, before continuing his strong run with a masterful victory in China under tricky conditions.
Kallio had built up a strong lead in the championship but his luck would soon change. After difficult races in France and Italy, the latter hampered by clutch issues at the start of the race, his bad luck continued in Catalunya when his bike broke down, crashed on his return to the pits, his healthy lead in the standings had vanished. His woes seemed to continue at Doningt
Road racing is a form of motorsport racing held on a paved road surfaces. The races can be held either on a closed circuit or on a street circuit utilizing temporarily closed public roads. Road races were held entirely on public roads however, public safety concerns led to most races being held on purpose built racing circuits. Road racing's origins were centered in Western Europe and Great Britain as motor vehicles became more common in the early 20th century. After the Second World War, automobile road races were organized into a series called the Formula One world championship sanctioned by the Fédération Internationale de l'Automobile while, motorcycle road races were organized into the Grand Prix motorcycle racing series now called MotoGP and sanctioned by the Fédération Internationale de Motocyclisme; the success and popularity of road racing has seen the sport spread across the globe with Grand Prix road races having been held on six continents. Other variations of road racing include.
The first organized automobile race was held on July 1894 from Paris to Rouen, France. The first held in the United States was a 54-mile competition from Chicago to Evanston and return, held on November 27, 1895. By 1905, the Gordon Bennett Cup, organized by the Automobile Club de France, was considered the most important race in the world. In 1904, the Association Internationale des Automobiles Clubs Reconnus was formed by several European automobile clubs. In 1904 the FIM created the international cup for motorcycles; the first international motorcycle road race took place in 1905 at France. After disagreeing with Bennett Cup organizers over regulations limiting the number of entrants, the French automobile manufacturers responded in 1906 by organizing the first French Grand Prix race held at Le Mans; the first 24 Hours of Le Mans endurance race was held in 1923. The great majority of road races were run over a lengthy circuit of closed public roads, not purpose-built racing circuits; this was true of the Le Mans circuit of the 1906 French Grand Prix, as well as the Targa Florio, the 75 miles German Kaiserpreis circuit in the Taunus mountains, the 48 miles French circuit at Dieppe, used for the 1907 Grand Prix and, the Isle of Man TT motorcycle road circuit first used in 1907.
The exceptions were the steeply banked egg-shaped near oval circuit of Brooklands in England, completed in 1906, the Indianapolis Motor Speedway, the oval, banked speedways constructed in Europe at Monza in 1922 and at Montlhéray in 1924. Road racing on public roads was banned in Great Britain in 1925 when a spectator was injured at the Kop Hill Climb event; the Royal Automobile Club and the Auto-Cycle Union stopped issuing permits for races on public roads, a policy that has not changed to this day. Donington Park was the first permanent park circuit in the United Kingdom and held its first motorcycle race in 1931; as automobile and motorcycle technology improved, racers began to achieve higher speeds that caused an increasing number of accidents on roads not designed for motorized vehicles. Public safety concerns caused the number of road racing events on public roads in Europe to decrease over the years; the Mille Miglia was a notable exception, allowed to continue until 1957. After the First World War and motorcycle road racing competitions in Europe and in North America went in different directions.
Automobile racing in the United States was oval track racing on tracks such as the Indianapolis Motor Speedway and the Milwaukee Mile track while, pre-war American motorcycle racers raced on dirt tracks using available horse racing circuits. American racing branched out into stock car racing and drag racing. Road racing traditions in Europe, South America, Great Britain and the British Commonwealth nations grew around races held on paved, public roads such as the Circuit de la Sarthe circuit near the town of Le Mans, the Spa-Francorchamps Circuit in Belgium and the Mount Panorama Circuit in Australia. Certain European race circuits were situated in mountainous regions where the topography meant that the roads featured numerous curves and elevation changes, allowing the creation of sinuous and undulating race courses such as the Nurburgring in the Eifel mountains of Germany and the Circuit de Charade in the Chaîne des Puys in the Massif Central of France; these circuits presented such a challenge that they were both respected by racers.
The 20.8 km long Nurburgring with more than 300 metres of elevation change from its lowest to highest points, was nicknamed "The Green Hell" by Jackie Stewart, due to its challenging nature. The sinuous track layout of the Charade circuit caused some drivers like Jochen Rindt in the 1969 French Grand Prix to complain of motion sickness, wore open face helmets just in case. In 1949 the FIM introduced the Grand Prix motorcycle racing world championship with the 1949 Isle of Man TT being the inaugural event. With the exception of the Monza circuit, all the Grand Prix races were held on street circuits; the Association Internationale des Automobiles Clubs Reconnus was renamed the Fédération Internationale de l’Automobile in 1946 and, plans were developed for a road racing world championship. In 1950, the FIA created the Formula One world championship, a competition of seven rounds that included the Indianapolis 500. A Formula I manufacturers' championship was begun in 1955. Auto racing was temporarily banned in several countries after the 1955 Le Mans disaster.
The tragedy highlighted the need for improved safety standards for both drivers and
The Sachsenring motorsport racing circuit is located in Hohenstein-Ernstthal near Chemnitz in Saxony, Germany. Among other events, it features the annual German motorcycle Grand Prix of the FIM Grand Prix motorcycle racing world championship; the first race was held on 26 May 1927 on an 8.7 km layout on public roads, running through the village of Hohenstein-Ernstthal itself. It was dubbed "Sachsenring" in 1937; the East German motorcycle Grand Prix was held there from 1962 to 1971. The local two stroke MZ bikes of Zschopau were competitive during this time; the quickest lap was achieved by 15 time World Champion Giacomo Agostini on a MV Agusta with a 180 km/h average. After West German Dieter Braun won in 1971 and the East German fans sang the West German National Anthem in celebration, the event was limited to East European entrants for political reasons. In 1990, with faster Western machinery now available, racing through the village became too dangerous with some fatalities. To accelerate redevelopment of eastern Germany in the new unified Germany, a 2.9 km short track berg corner was built in the 1990s to bring international motorsport to the newly freed eastern part of Germany.
In 1996, IDM motorcycle racing and the ADAC Super Tourenwagen Cup resumed racing here. The DTM raced here in 2000, with Klaus Ludwig winning at age 51, but the DTM did not return after 2002, preferring international venues. Since 1998, the German motorcycle Grand Prix moved to the Sachsenring from Nürburgring. In recent years, the track has been made longer again, with the length now being 3670m. Since 2007, the Sachsenring is part of the regular schedule of ADAC GT Masters. In 2011 the FIA GT1 World Championship held one of its race weekends at the Sachsenring. Wolfgang Hallmann: Das war der Sachsenring – Geschichte und Gegenwart einer legendären Rennstrecke.
Bridgestone Corporation is a multinational auto and truck parts manufacturer founded in 1931 by Shojiro Ishibashi in the city of Kurume, Japan. The name Bridgestone comes from a calque translation and transposition of ishibashi, meaning "stone bridge" in Japanese; as of 2017, the company is the largest manufacturer of tyres in the world, followed by Michelin, Goodyear and Pirelli. Bridgestone Group had 181 production facilities in 24 countries as of July 2018; the history of Bridgestone America dates back to the two separate companies that merged to form Bridgestone Tire company. The first one is Firestone Tire & Rubber Company, founded in August 1900 by Harvey Firestone and was headquartered in Akron, Ohio; the second one is Bridgestone Tire Company Ltd. founded in 1931 by Shojiro Ishibashi in Japan. The first Bridgestone tyre was produced on 9 April 1930, by the Japanese "Tabi" Socks Tyre Division. One year on 1 March 1931, the founder, Shojiro Ishibashi, made the "Tabi" Socks Tyre Division independent and established the Bridgestone Tyre Co. Ltd. in the city of Kurume, Fukuoka Prefecture.
"Bridgestone" was named after the name of Shojiro Ishibashi. Foregoing dependence on European and North American technology, the Bridgestone Tyre Co. Ltd. set its eyes on manufacturing tyres based on Japanese technology. The fledgling company experienced many difficulties in the areas of technology and sales in the early days. Improvements were achieved in quality and manufacturing processes which led to the business expanding in domestic and overseas markets. Wartime regulations were in effect throughout Japan, tyres came under the jurisdiction of these regulations; this resulted in nearly all of the company's output being used to satisfy military demand. 1945 saw the end of armed conflict. The Tokyo headquarters was destroyed during an aerial bombing raid, all overseas assets were lost; the plants in Kurume and Yokohama escaped unscathed, production was able to resume after the war ended. Brushing aside the problems caused by a labour union strike that lasted for forty-six days, the foundations of the company were further reinforced after this.
After World War II Bridgestone started manufacturing motorcycles, but its main income was from supplying tyres to its rival motorcycle makers such as Honda and Yamaha and it was decided to cease motorcycle manufacturing. In 1951, Bridgestone was the first company in Japan to begin selling rayon cord tyres, a five-year project to modernize production facilities was started; this year saw another Bridgestone building opened in Kyōbashi, which contained the Bridgestone Museum. Sales surpassed ten billion yen in 1953, placing Bridgestone at the top of the tyre industry in Japan, celebrations were held to commemorate the 25th anniversary of the company's foundation in Kurume; the sale of nylon tyres was started in 1959, work forged ahead with the construction of the new Tokyo plant, opened in 1960, in order to cope with the fast-expanding market for motorization. The company issued stock shares and was listed on the stock exchange in 1961. A new system of administration was ushered in by Shojiro Ishibashi as the chairman, Kanichiro Ishibashi as the president.
As part of the transition across to administrative reform, the Deming Plan in honour of W. Edwards Deming, which involves overall quality control activities, was adopted, the company was awarded the prestigious Deming Prize in 1968. Additions were built onto the Tokyo plant in 1962 to house the new Technical Centre, a progressive system of research and development was established. On the product front, 1967 saw the sale of the company's first radial tire, the RD10. Bridgestone's first overseas plant since the end of the war was opened in Singapore in 1965, production was commenced in Thailand in 1969; the 1960s for Bridgestone was an era of overseas expansion that included the establishment of Bridgestone America in the United States in 1967 to act as Bridgestone's USA representative sales branch. At the start of the period of Japan's economic stagnation, brought about by the first oil shock, the company was placing more emphasis on establishing its own technology for the manufacture of radial tires, it was at this time that further domestic plants were constructed and fitted out.
Its Super Filler Radial was placed on the market in 1978, in 1979 the company introduced the high-performance POTENZA radial tire, from an Italian word for power. The company was engaged in overseas expansion activities at this time. In addition to starting up production in Indonesia and Iran in 1976, it invested in a Taiwan tire manufacturer and purchased a tire plant and a plant for diversified products in Australia in 1980; the founder, Shojiro Ishibashi, died on 11 September 1976. On 1 March 1981, the company celebrated its 50th anniversary. At the same time, the company initiated activities to strengthen its home base that supported overseas expansion strategy with the aim of being ranked as one of the world's top three manufacturers of rubber products. New production facilities were established in Thailand, Poland, the United States and other countries; the company changed the name from Bridgestone Tyre Co. Ltd. to Bridgestone Corporation in 1984. In 1988, Bridgestone purchased the Firestone Rubber Company of Akron, Ohio.
Placing considerable financial and personnel resources into rebuilding Firestone after the purchase, Brid
