KZ900 NOS Ring set on ebay

I found these ring sets on ebay, price is OK.
They are 2nd over, 67mm, just like I have on my bike.
Are they worth anything?
NOS mean that they are old but new, is it?
Is there any chance that rings would broke from oldness?
It said that they are same rings for KZ900 and for KZ200!?

Yes, the ring set is rare. The price, at this time, is reasonable...and NOS (=New Old Stock) is fine, age will not affect the rings. Are you considering buying the set?

Yes, but I am waiting answer from seller, I need 4 sets, and I dont know how many of them he has got.

The only thing to be aware of is the possibility of corrosion on the rings. If they are rusty and you have to sand them down some that might not be good. But as McDroid said, age won't affect them other then corrosion. Good luck.

It looks like somebody else swooped on 'em.:S


I wouldn't worry to much though, because the way I read the auction details (and since pic is of only one ring set), you'd be searching forever trying to find another three ring sets in the same size to be able to do a complete rebore.

Yes that is what seller said. Only 1 set. I dont need them
for now. Maybe if I find whole set for 4 pistons I would buy them.
