KTM Piston question?

JW · Nov 6, 2002

Okay, I spoke with Eric Gorr and he told me to go with OEM for my top end so I punched in my part # 55530007000 and got back part #
55530007000/I
55530007000/II
What is the difference in these two. This is my first KTM and I am a little cofused by these two #s. :think: Any suggestions.
This is for a 1987 KTM 350
Tkanks guys :thumb:

Look on top of your old piston it should have a 1 or 2 printed in their. This means whether your bike was in production run 1 or production run 2 usually there a bee's d$%k worth of difference in some of the tolerances for the two production runs, hence two pistons based on which production run your bike came from.
