2021 Yamaha R1 Technical Analysis & Specification Breakdown

Positioned in Yamaha's sport motorcycle lineup, the 2021 Yamaha R1 features a 998 cc (60.9 cu in) liquid-cooled in-line four, four-stroke configuration. In factory specification, peak output is rated at 197.3 HP (144 kW) at 13,500 rpm while maximum torque reaches 113.3 Nm (83.6 lb-ft) at 11,500 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 197.7 HP per liter and a 2,000 rpm working window between peak torque (11,500 rpm) and peak power (13,500 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.

On the scales, the R1 measures 201 kg (443 lbs) wet (curb), translating to a power-to-weight ratio of 0.98 HP/kg (1.02 kg per horsepower). Rider ergonomics and chassis geometry center around a 855 mm (33.7 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,405 mm (55.3 in) wheelbase engineered for quick, flickable steering geometry. The 17-liter (4.5 US gal) fuel tank paired with a rated consumption of 7.2 L/100 km provides an estimated theoretical range of roughly 236 km (147 miles) between fill-ups.
