NARAKU sports variator for 2-stroke CPI, Keeway, Generic models, as well as all Chinese Minarelli-based replica engines. When calibrated, this variator provides good acceleration at higher top speeds. The restriction of the original variator is lifted giving a greater top end. The set comes with 5.7g Variator weights 15x12mm. These weights are suitable for scooters in original condition. If tuning components (e.g. exhaust system or counter pressure spring) are installed, we recommend that you re-calibrate the weights. We offer various kits and 15x12 weights.
