2009 Roehr 1250sc Technical Analysis & Specification Breakdown

Engineered by Roehr for the sport motorcycle segment, the 2009 Roehr 1250sc features a 1250 cc (76.3 cu in) liquid-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 180 HP (131.4 kW) at 9,100 rpm while maximum torque reaches 155.9 Nm (115 lb-ft) at 7,600 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 144 HP per liter and a 1,500 rpm working window between peak torque (7,600 rpm) and peak power (9,100 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.

On the scales, the 1250sc measures 196 kg (432 lbs) dry, translating to a power-to-weight ratio of 0.92 HP/kg (1.09 kg per horsepower). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,422 mm (56 in) wheelbase engineered for balanced agility and highway composure. The 14.38-liter (3.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
