Re-restricting an Aprilia RS50

I have bought an Aprilia RS 50 for my son to ride when he is 16 in march. I need to re restrict it but dont have a clue other than that I may need to change the exhaust. Any help would be appreciated.

Aprilia RS 50 Year?Model?

Hi Fredallen

Restricted ones will do 30mph and unrestricted ones do about 60mph,think the only restriction on a restricted model is a washer in the head of the exhaust port ie start of the expansion box(exhaust pipe.Give any main Aprilia dealer a bell they should be able to tell you exactly and advice you on how to re-restrict it and sell you the part.Good Luck
