2001 MBS 656 Technical Analysis & Specification Breakdown

Engineered by MBS for the sport motorcycle segment, the 2001 MBS 656 utilizes a 656 cc (40 cu in) in-line four, four-stroke layout. In factory specification, peak output is rated at 125 HP (91.2 kW) at 12,500 rpm while maximum torque reaches 75 Nm (55.3 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 190.5 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 656 measures 155 kg (342 lbs) dry, translating to a power-to-weight ratio of 0.81 HP/kg (1.24 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 1,380 mm (54.3 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, while factory top speed is listed at 250 km/h (155 mph).
