Built around Boss Hoss's custom - cruiser motorcycle platform, the 2019 Boss Hoss 57 Chevy Trike 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) 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 shaft drive (cardan) final drive. With a specific output of 71.8 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 57 Chevy Trike measures 680.4 kg (1500 lbs) dry, translating to a power-to-weight ratio of 0.65 HP/kg (1.53 kg per horsepower). Rider ergonomics and chassis geometry center around a 749 mm (29.5 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 2,159 mm (85 in) wheelbase engineered for planted straight-line stability. The 32.17-liter (8.5 US gal) fuel tank paired with a rated consumption of 8.55 L/100 km provides an estimated theoretical range of roughly 376 km (234 miles) between fill-ups.
