Stage6 Sport Pro MKII variator kit for Piaggio/ Vespa 50cc 4-stroke scooters.

This is the updated version of the Sport Pro variator, adjusted to meet the new technical standards of the Stage6 R&D department. This MKII variator has been optimised for use with 4-stroke engines with benefits noticeable throughout. The Sport Pro leads to smooth starts making the riding experience particularly pleasant. Optimized shifting and an increased power level improve acceleration and allow the possibility for higher top speeds. The Stage6 vairator ensures smooth shifting and greater mechanical smoothness even at high speeds, this system offers consistent performance that a standard scooter cannot offer. Stage6 claim this to be the most efficient tuning part at extracting the most power from the standard 4-stroke engines.

Stage6 recommend combining the Stage6 Sport Pro MKII variator with a Stage6 Sport Pro clutch, Stage6 clutch bell & new drive belt. A Stage6 rollers box set will make adjusting the variator easier.

Included: variator, spacers, 6x 19x15.5mm 9.0g rollers & soft torque spring.
