Ordering piston rings

[desmodromic]

I measured my piston and it has a 69mm diameter. Is that stock size or oversize?

 

[CDNTX650]

there is numbers on the top of the piston crowns. i forget the stock number though.

Measure again, that's 5 or 6mm too small. Stock size is just under 75mm.

Ok, will do. I doubt I am off by that much

So I measured something of a Ducati I was working on and I wrote it down on my xs 650 yellow pad. It was my mistake, you were right the piston is in the 75mm range. Thanks for the help
