WISECO - 868M05400 - Piston Kit - 54.00 mm - Beta | Gas Gas | Husaberg | Husqvarna | KTM
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 868M05400 is a precision-engineered piston kit for 54.00 mm / Beta | Gas Gas | Husaberg | Husqvarna | KTM engines, built to hold dimensional tolerances across thousands of heat cycles. Endurance and high rpm, giving you the kind of fit-from-day-one accuracy that prevents premature wear on the cylinder wall, wrist pin, and rings. Each piston is electra-coated on the dome, ring groove, and pin bore, for maximum wear resistance and protection from micro-welding, galling and detonation. Model: GP Series. Whether you are overboring for more displacement or simply replacing what age and hours have worn out, the 868M05400 gives you a forged foundation you can trust.
