Polini Variator Maxi Hi-Speed Evolution Yamaha T-Max 530cc after 2017

Scooter tuning made in Italy: Polini Variator Maxi Hi Speed Evolution for Yamaha T-Max 530cc (after 2017).

The Hi-Speed CVT is a genuine technological masterpiece. Its stand-out feature is the internal lubrication system with two-in-built o-rings that reduces frictional power losses and increases reliability and life expectancy. A big internal pocket contains the grease, and a special spring allows for continuous lube distribution even under exreme conditions.

Running surface, angles and polished roller tracks were redesigned and optimized for increased acceleration and improved top speed. The variator sleeve is made from chromed nickel with DLC carbon treatment (used in racing and aircraft applications) to further reduce friction and abrasive wear.

The CVT comes with a reinforced torque spring and two matching sets of 25x15mm roller weights (12g + 14g).

The roller coating is a new mixture of nylon and aramidic fibers. In combination with the polished roller tracks friction is minimized which in turn leads to smoother shifting properties and better acceleration.
