Technical Overview
2023 Boss Hoss Dragon Technical Analysis & Specification Breakdown
At the heart of the 2023 Boss Hoss Dragon custom - cruiser motorcycle, Boss features a 6300 cc (384.4 cu in) liquid-cooled v8, four-stroke configuration. In factory specification, peak output is rated at 430 HP (313.9 kW) while maximum torque reaches 610.2 Nm (450.1 lb-ft) at 3,800 rpm, transferring power to the rear wheel through a automatic gearbox and shaft drive (cardan) final drive. With a specific output of 68.3 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
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.
