I have a bike, a rm 125 and not sure what year it is. Anyone know how I can find that out using the serial number? I am in need of a cylinder with exhaust valves or just the exhaust valves. I think it is a 1992 but not sure. Any info would be great. If it is a 92 will a 93 or 94 cylinder work? Thanx.

Can you tell me what your tenth digit is? thats the letter that determines year, for suzukis and yamahas at least. Z is an 82, lower letters are earlier years.
