1997 Bimota YB11 Technical Analysis & Specification Breakdown

At the heart of the 1997 Bimota YB11 sport motorcycle, Bimota relies on a 1002 cc (61.1 cu in) liquid-cooled in-line four, four-stroke powerplant. In factory specification, peak output is rated at 145 HP (105.8 kW) at 10,000 rpm while maximum torque reaches 110 Nm (81.1 lb-ft) at 8,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 144.7 HP per liter and a 1,500 rpm working window between peak torque (8,500 rpm) and peak power (10,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.

On the scales, the YB11 measures 183 kg (403 lbs) dry, translating to a power-to-weight ratio of 0.79 HP/kg (1.26 kg per horsepower). Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance.
