WISECO - PK1018 - Piston Kit with Gaskets - 83.00 mm - Yamaha
Engine rebuilds are only as good as the parts that go back in, and when it comes to the piston — the component under more sustained thermal and mechanical stress than anything else in the top end — there is no room for compromise. The WISECO PK1018 is a precision-engineered piston kit with gaskets for 83.00 mm / Yamaha engines, built to hold dimensional tolerances across thousands of heat cycles. Complete piston kit includes pistons, rings, wrist pins, circlips and top-end gasket kit for one complete engine, giving you the kind of fit-from-day-one accuracy that prevents premature wear on the cylinder wall, wrist pin, and rings. Wiseco ring types are not interchangeable (i.e., CD is not interchangeable with LC). Type: Top End. Whether you are overboring for more displacement or simply replacing what age and hours have worn out, the PK1018 gives you a forged foundation you can trust.
