Engineered by Yamaha for the cross - motocross motorcycle segment, the 2010 Yamaha YZ250F utilizes a 250 cc (15.3 cu in) liquid-cooled single cylinder, four-stroke layout. Internal engine geometry specifies a bore and stroke of 77.0 x 53.6 mm (3.0 x 2.1 inches) with a 13.5:1 compression ratio.
On the scales, the YZ250F measures 102 kg (225 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 988 mm (38.9 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,466 mm (57.7 in) wheelbase engineered for balanced agility and highway composure. The 6.43-liter (1.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
