Good day to all of you. I am currently wondering if these two Yamaha parts are interchangable: 3LN-11610-20 (fzx250zeal, fzr250r) & 50M-11610-20 (xv250virago). They are 0.5mm O/S piston rings. As you can see they only differ in the first 3 characters which designate the model that the part was FIRST used on. I got no answer from further studying Yamaha part number theory. Please post what you think!

Going by the last 7 digits I would think there were the same however, the Virago is a twin and the FZR is a 4 so the displacement per piston is different unless the stroke on the Virago about twice as long.

I'm assuming your looking at the Virago pistons as you found some cheap.;-)

I'm only guessing myself though so its your choice.
