Engineered by Yamaha for the enduro - offroad motorcycle segment, the 2022 Yamaha WR155R pairs a 155 cc (9.5 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 16.7 HP (12.2 kW) at 10,000 rpm while maximum torque reaches 14.3 Nm (10.5 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 107.7 HP per liter and a 3,500 rpm working window between peak torque (6,500 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 WR155R measures 134 kg (295 lbs) wet (curb), translating to a power-to-weight ratio of 0.12 HP/kg (8.02 kg per horsepower). Rider ergonomics and chassis geometry center around a 880 mm (34.6 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 8.1-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
