Light, powerful and tuned for cross country competition, the YZ250X is Yamaha's ultimate two-stroke woods racer.
Based on the legendary 249cc YZ liquid-cooled reed-valve-inducted two-stroke engine, the YZ250X is focused on off-road competition featuring an 18-inch rear wheel, wide-ratio gearing - five speed in this case - standard side stand, sealed O-ring chain, reserve fuel petcock, and scraper between the fork's dust and oil seal, all adding up to exciting performance.
