We stock over 10 Racetour pistons 68-72.5mm
MRB were one of the first scooter tuners to really get into the use of Japanese quality pistons. This lead to a lot of cylinder machining and crankshaft alterations to make them fit the Lambretta configuration. We have therefore launched our racetour pistons which are made to Lambretta type dimensions so they will go straight into cylinders and use a crankshaft with a 107mm conrod.
