Built around Boss Hoss's custom - cruiser motorcycle platform, the 2009 Boss Hoss BHC-9 LS2 Trike relies on a 6000 cc (366.1 cu in) liquid-cooled v8, four-stroke powerplant. In factory specification, peak output is rated at 425 HP (310.2 kW) at 5,250 rpm while maximum torque reaches 576.3 Nm (425.1 lb-ft) at 5,250 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 70.8 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 BHC-9 LS2 Trike measures 528.4 kg (1165 lbs) dry, translating to a power-to-weight ratio of 0.8 HP/kg (1.24 kg per horsepower). Rider ergonomics and chassis geometry center around a 635 mm (25 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,956 mm (77 in) wheelbase engineered for planted straight-line stability. The 32.17-liter (8.5 US gal) fuel tank paired with a rated consumption of 10 L/100 km provides an estimated theoretical range of roughly 322 km (200 miles) between fill-ups.
