XT250X

2011 Yamaha XT250X Technical Analysis & Specification Breakdown

Engineered by Yamaha for the super motard motorcycle segment, the 2011 Yamaha XT250X relies on a 249 cc (15.2 cu in) oil & air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 21 HP (15.3 kW) at 7,500 rpm while maximum torque reaches 21 Nm (15.5 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 84.3 HP per liter and a 1,000 rpm working window between peak torque (6,500 rpm) and peak power (7,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

On the scales, the XT250X measures 133 kg (293 lbs) dry, translating to a power-to-weight ratio of 0.16 HP/kg (6.33 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,365 mm (53.7 in) wheelbase engineered for quick, flickable steering geometry. The 11-liter (2.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
