[mad_max]

I just bought a go-kart with a RMX250 motor in it and it needs a new piston. but to get a new piston I need to know what year it is

The engine number is J113-103215

I dont know how to find out the year from this

Cheers

Doesn't answer your question completely but gives you an understanding of what the numbers mean. (1/2 way down the page)

Looking at this page suggests it is post 1994, but not by much.

most older rmx 250s were jap imports so ring your local suzuki dealer and give them this number and they should be able to contact japan to give you al etails on this bike
