2022 Bimota KB4 Technical Analysis & Specification Breakdown

At the heart of the 2022 Bimota KB4 sport motorcycle, Bimota utilizes a 1043 cc (63.6 cu in) liquid-cooled in-line four, four-stroke layout. In factory specification, peak output is rated at 140.1 HP (102.3 kW) at 10,000 rpm while maximum torque reaches 111 Nm (81.9 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 134.3 HP per liter and a 2,000 rpm working window between peak torque (8,000 rpm) and peak power (10,000 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

On the scales, the KB4 measures 194 kg (428 lbs) wet (curb), translating to a power-to-weight ratio of 0.72 HP/kg (1.38 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 1,390 mm (54.7 in) wheelbase engineered for quick, flickable steering geometry. The 19-liter (5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
