Centurion was a brand of bicycles created in 1969 by Mitchell (Mitch) M. Weiner and Junya (Cozy) Yamakoshi, who co-founded Western States Import Co. (WSI) in Canoga Park, California to design, specify, distribute and market the bicycles. The bikes themselves were manufactured initially in Japan by companies including H. Teams Company of Kobe and later in Taiwan by companies including Merida. The Centurion brand was consolidated with WSI's mountain bike brand DiamondBack in 1990. WSI ceased operations in 2000.
