Polini 6.5 – 9 Gram Roller Tuning Kit 19 x 15.5mm
Includes weight: 6.5-7.0-8.0-9.0g
Scooter tuning can often be won or lost in the transmission. This clever kit allows you to exchange the weight component of the roller from the outer plastic shell, giving you a huge array of combinations for fine tuning of your transmission. The kit includes 6 rollers of each weight of 6.5, 7, 8 and 9 gram weight inserts – and remember, you can run combinations in between that of 3 x 3, giving you am incredible amount of tunability. The outer plastic shells can also be purchased separately when they wear out!
Another relevant factor, is both the Malossi Multivar 2000 and the Malossi MHR Team variator for Piaggio hiper2 motor (found in almost all 2T 50cc Aprilia, Piaggio and Vespa models) both use the same 19×15.5mm roller size – so if you upgrade your variator in the future, you’ll still be able to use this roller kit with it!
