In factory specification, peak output is rated at 45.3 HP (33.1 kW) at 6,750 rpm while maximum torque reaches 53 Nm (39.1 lb-ft) at 6,750 rpm, transferring power to the rear wheel through belt final drive. With a specific output of 85.5 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 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 1,575 mm (62 in) wheelbase engineered for planted straight-line stability.
