Aprilia SR50 (Piaggio Engine)
s23 10/12mm axle shim kit reducer
I've ran into the issue myself many times, and this should have been done long ago. If you have 12mm legs, this allows you to run a 10mm axle. CNC alum, installs in seconds. Great for the guys looking to run japan wheels/10mm axle on taiwan style legs. Simply slide these into the legs before installing the axle. Easy peasy. 1 order comes with 2 shims.
