2010 Yamaha WR250R Technical Analysis & Specification Breakdown

At the heart of the 2010 Yamaha WR250R enduro - offroad motorcycle, Yamaha utilizes a 250 cc (15.3 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 30.3 HP (22.1 kW) at 10,000 rpm while maximum torque reaches 23.7 Nm (17.5 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 121.2 HP per liter and a 2,000 rpm working window between peak torque (8,000 rpm) and peak power (10,000 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

On the scales, the WR250R measures 135.2 kg (298 lbs) wet (curb), translating to a power-to-weight ratio of 0.22 HP/kg (4.46 kg per horsepower). Rider ergonomics and chassis geometry center around a 930 mm (36.6 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,420 mm (55.9 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, while factory top speed is listed at 132 km/h (82 mph).
