In factory specification, peak output is rated at 24.7 HP (18 kW), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 99 HP per liter, the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

Rider ergonomics and chassis geometry center around a 1,320 mm (52 in) wheelbase engineered for quick, flickable steering geometry.
