Built around Yamaha's enduro - offroad motorcycle platform, the 2018 Yamaha XT250 pairs a 249 cc (15.2 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 74.0 x 58.0 mm (2.9 x 2.3 inches) with a 9.5:1 compression ratio.
On the scales, the XT250 measures 132 kg (291 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,359 mm (53.5 in) wheelbase engineered for quick, flickable steering geometry. The 9.84-liter (2.6 US gal) fuel tank paired with a rated consumption of 3.1 L/100 km provides an estimated theoretical range of roughly 317 km (197 miles) between fill-ups.
