YZF-R1 LE

2011 Yamaha YZF-R1 LE Technical Analysis & Specification Breakdown

Engineered by Yamaha for the sport motorcycle segment, the 2011 Yamaha YZF-R1 LE relies on a 998 cc (60.9 cu in) liquid-cooled in-line four, four-stroke powerplant. In factory specification, peak output is rated at 179.6 HP (131.1 kW) at 12,500 rpm while maximum torque reaches 115 Nm (84.8 lb-ft) at 10,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 180 HP per liter and a 2,500 rpm working window between peak torque (10,000 rpm) and peak power (12,500 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.

On the scales, the YZF-R1 LE measures 205.9 kg (454 lbs) wet (curb), translating to a power-to-weight ratio of 0.87 HP/kg (1.15 kg per horsepower). Rider ergonomics and chassis geometry center around a 833 mm (32.8 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,415 mm (55.7 in) wheelbase engineered for quick, flickable steering geometry. The 18.17-liter (4.8 US gal) fuel tank paired with a rated consumption of 7.13 L/100 km provides an estimated theoretical range of roughly 255 km (158 miles) between fill-ups.
