variator / vario kit Naraku sport for Piaggio (98-) NK900.94 fitting for Aprilia SR Street 50 TEA00 2007, 3,7 PS, 2,7 kw

NARAKU sports variator for Piaggio engines from1998 on. 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.
