Built around Yamaha's super motard motorcycle platform, the 2010 Yamaha WR 125X features a 124.7 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 14.8 HP (10.8 kW) while maximum torque reaches 12.2 Nm (9 lb-ft), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 118.7 HP per liter, 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 WR 125X measures 137 kg (302 lbs) wet (curb), translating to a power-to-weight ratio of 0.11 HP/kg (9.26 kg per horsepower). Rider ergonomics and chassis geometry center around a 920 mm (36.2 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,430 mm (56.3 in) wheelbase engineered for balanced agility and highway composure. The 8.5-liter (2.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
