At the heart of the 2022 Yamaha YZ250 cross - motocross motorcycle, Yamaha relies on a 249 cc (15.2 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 66.4 x 72.0 mm (2.6 x 2.8 inches) with a 10.6:1 compression ratio.
On the scales, the YZ250 measures 103 kg (227 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 970 mm (38.2 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,481 mm (58.3 in) wheelbase engineered for balanced agility and highway composure. The 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
