POLINI VARIATOR YAMAHA Zuma 125cc
The Variator is a small, but very important tuning part in the scooter - the heart of each automatic scooter motor. That‘s why renowned firms like POLINI use all their technical know how to produce optimal products that leave serial products far behind them. Our recommendation - variator installation as a must for all 2 & 4 stroke riders who want the very best for and out of their vehicles. THE ROLLERS THAT COME IN THE KIT ARE 20X17 9gm
Getting a second set of rollers in a different weight will give the advantage of "tuning" for your riding preferences.
Also Check the belt...it is probably worn out...a good belt insures you get maximum performance from the variator.
Adding the NCY fan also is a performance addition!
