Built around Yamaha's sport motorcycle platform, the 2002 Yamaha YZF-R6 relies on a 600 cc (36.6 cu in) liquid-cooled in-line four, four-stroke powerplant. In factory specification, peak output is rated at 120 HP (87.6 kW) at 13,000 rpm while maximum torque reaches 68.1 Nm (50.2 lb-ft) at 11,500 rpm. With a specific output of 200 HP per liter and a 1,500 rpm working window between peak torque (11,500 rpm) and peak power (13,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the YZF-R6 measures 168 kg (370 lbs) dry, translating to a power-to-weight ratio of 0.71 HP/kg (1.4 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 1,380 mm (54.3 in) wheelbase engineered for quick, flickable steering geometry.

Compare engine output with similar motorcycles if acceleration, highway use or two-up riding matters.
Torque
Torque is useful for judging real-world pull, especially for touring, commuting and loaded riding.
Seat Height
Check the seat height against your inseam and riding posture before choosing a motorcycle.
Weight
Compare weight carefully because it affects low-speed handling, parking and confidence.
Brakes
Brake setup is worth comparing if you ride in traffic, mountains or with a passenger.
