Polini have released a new variator specifically aimed at increasing the performance of Yamaha/Minarelli 50cc engines.
Fitting an aftermarket variator is one of the easiest ways to change the characteristics of an automatic engine. Acceleration and top speed can both be improved.
This Polini Hi Speed Evolution R02 variator includes n6 rollers, an 8% stronger spring and comes complete with an Evo slider, anti-torsion system for the spring and a larger diameter chrome pin to reduce friction and durability.
Polini are also promising lower maintenance costs due to improved lubrication of the bush and pin, polishing of the ramps and improved quality of the roller material to increase resistance to wear.
It costs £76 plus VAT, has the part number: 241.731, is compatible with electric start Yamaha/Minarelli engines and is available from your local Polini dealer, or visit Polini for the full range of tuning products.
