At the heart of the 2010 Boss Hoss BHC-9 LS3 Trike custom - cruiser motorcycle, Boss Hoss features a 6200 cc (378.3 cu in) liquid-cooled v8, four-stroke configuration. In factory specification, peak output is rated at 445 HP (324.8 kW) at 5,750 rpm while maximum torque reaches 603.4 Nm (445.1 lb-ft) at 4,750 rpm, transferring power to the rear wheel through belt final drive. With a specific output of 71.8 HP per liter and a 1,000 rpm working window between peak torque (4,750 rpm) and peak power (5,750 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the BHC-9 LS3 Trike measures 660 kg (1455 lbs) dry, translating to a power-to-weight ratio of 0.67 HP/kg (1.48 kg per horsepower). Rider ergonomics and chassis geometry center around a 737 mm (29 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops.
