2008 BucciMoto BR1R SM 140 Technical Analysis & Specification Breakdown
At the heart of the 2008 BucciMoto BR1R SM 140 super motard motorcycle, BucciMoto features a 140 cc (8.5 cu in) oil & air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 11 HP (8 kW) at 11,000 rpm, transferring power to the rear wheel through a 4-speed gearbox. With a specific output of 78.6 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the BR1R SM 140 measures 67 kg (148 lbs) dry, translating to a power-to-weight ratio of 0.16 HP/kg (6.09 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,150 mm (45.3 in) wheelbase engineered for quick, flickable steering geometry. The 3.5-liter (0.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
