Spacer shim 0.1-0.5mm Yamaha 16mm CVT

This shim is for adjusting the distance between variator halves (fixed, driven face and variator sheave).

Add these for more acceleration and lower top speed, or use one of these thin ones in place of a thicker factory one for less acceleration and higher top speed.

To suit Yamaha 50cc - 90cc engines with 16mm cranks, some Taiwanese and European Minarelli engines, some Chinese horizontal 2 strokes may include Urban, Vmoto etc (check first)

Inside diameter is 16mm

Please choose required thickness from the drop down menu.
