1975 RM125S vs M Pistons
« on: December 02, 2017, 04:54:43 AM »
Can someone post the part numbers of Suzuki Pistons and Rings for the '75 RM125S Model Please.
I can only find Part numbers for the M model.
I have a stock piston here that has thinner rings and I'm wondering if the S model came that way.

Yeah S piston rings were very thin to reduce friction but they also wear a lot faster.I've got some spare std size S rings and a .5 over S piston though no rings
