Vehicle Information
Yamaha WR250R Motorcycle - Dual-Sport (1991-2020)
The Yamaha WR250R is a dual-sport motorcycle renowned for its versatility and reliability, produced from 2008 to 2020. It is powered by a 249cc liquid-cooled, DOHC, single-cylinder engine with electronic fuel injection, delivering 29.5 to 31 horsepower and approximately 24 Nm of torque. Designed to excel both on and off-road, the WR250R maintained a stable mechanical platform throughout its production run. A supermoto variant, the WR250X (2007-2017), shared the same mechanical base, differing primarily in its street-oriented tires and sprockets. The model saw minor cosmetic changes, but its technical core remained consistent. Q: Is this part compatible with my Yamaha WR250R?
R: To confirm exact compatibility, please use the year and edition selector at the top of the page.
