Technical Overview
1998 Bimota YB9 SR Technical Analysis & Specification Breakdown
Engineered by Bimota for the sport motorcycle segment, the 1998 Bimota YB9 SR features a 599 cc (36.6 cu in) liquid-cooled in-line four, four-stroke configuration. In factory specification, peak output is rated at 100 HP (73 kW) at 12,500 rpm while maximum torque reaches 65 Nm (47.9 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 166.9 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 YB9 SR measures 173 kg (381 lbs) dry, translating to a power-to-weight ratio of 0.58 HP/kg (1.73 kg per horsepower). Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance.
