At the heart of the 2010 Leonhardt Gunbus 410 sport motorcycle, Leonhardt features a 6719.1 cc (410 cu in) v2, four-stroke configuration. In factory specification, maximum torque reaches 710 Nm (523.7 lb-ft) at 1,900 rpm, transferring power to the rear wheel through a 3-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 176.0 x 156.0 mm (6.9 x 6.1 inches) with a 8.7:1 compression ratio.
On the scales, the Gunbus 410 measures 650 kg (1433 lbs) dry. Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 2,410 mm (94.9 in) wheelbase engineered for planted straight-line stability.
