2006 Yamaha YZF-R1SP Technical Analysis & Specification Breakdown

Built around Yamaha's sport motorcycle platform, the 2006 Yamaha YZF-R1SP features a 998 cc (60.9 cu in) liquid-cooled in-line four, four-stroke configuration. In factory specification, peak output is rated at 172.6 HP (126 kW) at 12,500 rpm while maximum torque reaches 106.6 Nm (78.6 lb-ft) at 10,900 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 172.9 HP per liter and a 1,600 rpm working window between peak torque (10,900 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-R1SP measures 174 kg (384 lbs) dry, translating to a power-to-weight ratio of 0.99 HP/kg (1.01 kg per horsepower). Rider ergonomics and chassis geometry center around a 835 mm (32.9 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-liter (4.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
