Built around Yamaha's allround motorcycle platform, the 2009 Yamaha WR250X relies on a 250 cc (15.3 cu in) liquid-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 77.0 x 53.6 mm (3.0 x 2.1 inches) with a 11.8:1 compression ratio.
On the scales, the WR250X measures 135.6 kg (299 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 894 mm (35.2 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,425 mm (56.1 in) wheelbase engineered for balanced agility and highway composure. The 7.57-liter (2 US gal) fuel tank paired with a rated consumption of 3.31 L/100 km provides an estimated theoretical range of roughly 229 km (142 miles) between fill-ups.
