1999 Bimota Supermono Biposto Technical Analysis & Specification Breakdown

At the heart of the 1999 Bimota Supermono Biposto sport motorcycle, Bimota relies on a 652 cc (39.8 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 48 HP (35 kW) at 6,500 rpm while maximum torque reaches 60 Nm (44.3 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 73.6 HP per liter and a 500 rpm working window between peak torque (6,000 rpm) and peak power (6,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

On the scales, the Supermono Biposto measures 176 kg (388 lbs) wet (curb), translating to a power-to-weight ratio of 0.27 HP/kg (3.67 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, combined with a 1,340 mm (52.8 in) wheelbase engineered for quick, flickable steering geometry. The 16-liter (4.2 US gal) fuel tank paired with a rated consumption of 6.1 L/100 km provides an estimated theoretical range of roughly 262 km (163 miles) between fill-ups, while factory top speed is listed at 183 km/h (114 mph).
