variator / vario kit Naraku sport for Morini NK900.92

NARAKU sports variator for Morini 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 8g Variator weights 16x13mm. 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 16x13 weights.
