47X 1KT Yamaha TZR250 RZV500 piston rings

Yamaha TZR250 + RD500 + RZV500 - new Yamaha piston ring sets x2. These are standard size (i.e. not over size or re-bored). Yes you can buy cheaper after market piston ring kits, but this is genuine Yamaha. Aimed at those who want the best for their bike and are prepared to pay a bit more. Price is each (i.e. a set = both rings for one piston), so you need 4 sets for an engine.
