Performance Upgrades and Features
-
Significant Horsepower Boost: Increases maximum power from the stock factory baseline of approximately 11.5 PS up to a potent 13 PS. Experience a noticeable increase in acceleration and pulling power throughout the entire RPM range.
-
Linear and Efficient Power Delivery: Provides a smoother, more stable power curve that eliminates the high-speed power fade common with OEM setups. This achieves the perfect balance between aggressive low-end acceleration and efficient long-distance cruising.
-
Extended Top Speed Limit: Paired with the included +5mm extended CVT belt, this kit safely pushes the top speed ceiling from the factory limit of 118 km/h (approx. 73 mph) up to an incredible 140 km/h (approx. 87 mph).
Important Configuration Notes
-
Specialized Setup: The optimized top speed and acceleration curves are engineered specifically to work in tandem with the included +5mm extended belt. Utilizing standard-length or third-party belts will alter the performance profile and require separate transmission adjustments.
-
Straight-Groove Driver: For maximum efficiency and performance longevity, the secondary sliding sheave is designed with a straight-groove configuration to deliver optimal back-shift response.
