In factory specification, peak output is rated at 49.6 HP (36.2 kW) at 7,000 rpm while maximum torque reaches 56 Nm (41.3 lb-ft) at 5,500 rpm. With a specific output of 73.5 HP per liter and a 1,500 rpm working window between peak torque (5,500 rpm) and peak power (7,000 rpm), 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 1,455 mm (57.3 in) wheelbase engineered for balanced agility and highway composure.
