YZF R1

2002 Yamaha YZF R1 Technical Analysis & Specification Breakdown

Positioned in Yamaha's sport motorcycle lineup, the 2002 Yamaha YZF R1 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 152 HP (110.9 kW) at 10,500 rpm while maximum torque reaches 104.9 Nm (77.4 lb-ft) at 8,500 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 152.3 HP per liter and a 2,000 rpm working window between peak torque (8,500 rpm) and peak power (10,500 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.

On the scales, the YZF R1 measures 174 kg (384 lbs) dry, translating to a power-to-weight ratio of 0.87 HP/kg (1.14 kg per horsepower). Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,395 mm (54.9 in) wheelbase engineered for quick, flickable steering geometry.
