Built around Yamaha's sport motorcycle platform, the 2006 Yamaha YZF-R6 features a 599 cc (36.6 cu in) liquid-cooled in-line four, four-stroke configuration. In factory specification, peak output is rated at 131.2 HP (95.7 kW) at 14,500 rpm while maximum torque reaches 68 Nm (50.2 lb-ft) at 6,930 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 219 HP per liter and a 7,570 rpm working window between peak torque (6,930 rpm) and peak power (14,500 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 161 kg (355 lbs) dry, translating to a power-to-weight ratio of 0.81 HP/kg (1.23 kg per horsepower). Rider ergonomics and chassis geometry center around a 850 mm (33.5 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. The 17.5-liter (4.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
