Front Pulley (fixed) Polini Evolution Yamaha Tmax 530cc

Polini Front Pulley Air Speed (fixed) Evolution Yamaha T-Max 530cc. Designed to go with Polini’s variator ” Maxi Hi Speed”, but you can also use it as a replacement part for your original or other variator.

The pulley / fanwheel has large fins meaning that the variator is cooled more efficiently and that the belt has improved grip; improved grip means reduced loss of power which translates into more power on the rear wheel.
