2017 Boss Hoss BHC-3 LS3 SS Technical Analysis & Specification Breakdown
At the heart of the 2017 Boss Hoss BHC-3 LS3 SS custom - cruiser motorcycle, Boss Hoss pairs a 6200 cc (378.3 cu in) liquid-cooled v8, four-stroke architecture with road-focused gearing. 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 a automatic gearbox and 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-3 LS3 SS measures 483.1 kg (1065 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 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 9.8 L/100 km provides an estimated theoretical range of roughly 328 km (204 miles) between fill-ups.
