At the heart of the 2020 Yamaha XT250 trial motorcycle, Yamaha 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. The 8-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 112 km/h (70 mph).
