Engineered by BucciMoto for the cross - motocross motorcycle segment, the 2009 BucciMoto BR1-F4 Cross 10-12 pairs a 150 cc (9.2 cu in) oil & air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 11 HP (8 kW) at 11,000 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 73.3 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 BR1-F4 Cross 10-12 measures 62 kg (137 lbs) dry, translating to a power-to-weight ratio of 0.18 HP/kg (5.64 kg per horsepower). Rider ergonomics and chassis geometry center around a 830 mm (32.7 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, 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.
