Variator Polini Maxi Hi-Speed for Yamaha X-Max 125i 21- E5 (SEH3/ B9Y)

Description

Polini Maxi Hi-Speed ​​variator is one of the most powerful in the maxi scooter range. Attention was paid to the design of the polished roller tracks, which make more optimal use of the existing engine power band than the original variator. This means that the variator ratio changes in a torque-friendly rpm range. This results in increased acceleration and a slightly higher final speed.

Polini variator is also notable for its quality of workmanship and reliability. The sealed plain bearing with a cleanly machined bearing sleeve significantly reduces friction values ​​and dirt load when sliding. Perfect switching behavior and long service life due to reduced wear!

Compared to the original spring, the 18% stiffer counter-pressure spring ensures a higher engine speed when starting.

The included variator rollers 19×17 mm – 8.2 g have a coating of nylon and aramid fibers.

Instructions are also included.
