Does anyone know a website where I can find the year differneces of the Rm250's? I have a RM on my microsprint and I'm trying to find out th exact year. The book I got is from a 92 but the piston shows one ring, while mine has two. Thanks

 

Your Suzuki dealers should be able to pin point your engine year/model if you give him the engine crankcase numbers.

one ring / two ring deal ? several Rm models use oem pistons that are one ring, is the piston in there a Wiseco or some other aftermarket and by chance is a two ring ?
