Polini Performance Variator Kit; Yamaha Zuma 50

This Polini Performance Variator Kit is THE standard for upgrading the variator on your Yamaha Zuma. Widely accepted as the best variator on the market, this Polini version adds performance across the entire power band from take-off to top speed. Don't believe us? Google it. 

Benefits:

• The new and improved design allows the pulley face to sit closer to and extend farther away from the ramp plate, resulting in bumped up power on the low end.
• The drive belt now rides higher up on the pulley face, allowing for higher top speeds.
• The higher the drive belt rides on the pulley face, the lower your engine revs at full throttle, saving you gas and engine wear.

Adding the NCY Performance CDI will get your GET engine over 45MPH comfortably.
