When performing a top-end refresh, always inspect your cam chain for wear and ensure your cylinder walls are free of deep vertical scoring. Using a new top-end gasket kit and fresh synthetic oil is essential to protect your new high-compression forged piston during the critical first hours of operation.\u003c\/p\u003e\n\n\u003ch3\u003eFitment List\u003c\/h3\u003e\n\u003ctable border=\"1\" cellpadding=\"8\" style=\"width: 100%; border-collapse: collapse;\"\u003e\n    \u003cthead\u003e\n        \u003ctr\u003e\n            \u003cth\u003eYear Range\u003c\/th\u003e\n            \u003cth\u003eVehicle Brand\u003c\/th\u003e\n            \u003cth\u003eVehicle Model\u003c\/th\u003e\n        \u003c\/tr\u003e\n    \u003c\/thead\u003e\n    \u003ctbody\u003e\n        \u003ctr\u003e\n            \u003ctd\u003e2013-2014\u003c\/td\u003e\n            \u003ctd\u003eKawasaki\u003c\/td\u003e\n            \u003ctd\u003eKX450F\u003c\/td\u003e\n        \u003c\/tr\u003e\n    \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eQ: Is this a Standard Size piston?\u003c\/b\u003e\u003cbr\u003e\nA: Yes, this is the 95.96mm piston designed for the standard 96.00mm bore. It is the correct choice for cylinders that are within factory service limits and do not require boring.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003eQ: Does this kit include the gaskets?\u003c\/b\u003e\u003cbr\u003e\nA: No, the kit includes the forged piston, rings, wrist pin, and locks.
