The Suzuki SV1000 and the half-faired SV1000S are naked bike motorcycles made by Suzuki since 2003. The 996 cc (60.8 cu in) displacement 90° V-twin motorcycles were aimed to compete directly with the Honda VTR1000F, which was released prior to the Suzuki, and the low end Ducati one-litre V-twin engined sport bikes. The SV1000 is the larger version of the popular 650 cc SV650 motorcycle. The SV1000 shares many common parts with the SV650, including all bodywork, but the main frame, handlebars, swingarm and forks are different. The front forks and brakes are sourced from the earlier GSX-R600. The SV1000's engine is sourced from the TL1000S which, inside were over 300 changes to improve low-end and midrange performance.

The Suzuki SV650 and its variants are street motorcycles manufactured since 1999 by Suzuki. In 2009, Suzuki replaced the standard SV650 with the SFV650 Gladius. In 2016, the Gladius name was discontinued and the 2017 model was reverted to SV650.
