Because of the specialized coatings, we recommend a heat-cycle break-in process. Allow the engine to reach operating temperature, then let it cool completely before repeating. Avoid sustained high-RPM operation for the first tank of fuel.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this a standard compression piston?\u003c\/strong\u003e\u003cbr\u003eA: Yes, this RE904M05400 kit is designed to OEM specifications for bore and compression ratio, making it an ideal drop-in performance replacement for your 125cc engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e When installing a new piston, never skip measuring your ring end gap. Even with premium pistons, checking the clearance ensures your rings won't butt together when the engine reaches racing temperatures. It takes two minutes and can save you from a catastrophic top-end failure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/ktm-125-sx-and-150-sx-performance-upgrades-engine-mods-and-accessories-moto-house-mx\"\u003eKTM 125 SX Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/husqvarna-tc-125-performance-parts-and-accessories-moto-house-mx\"\u003eHusqvarna TC 125 Performance Parts\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/gas-gas-mc-125-performance-parts-and-accessories-moto-house-mx\"\u003eGas Gas MC 125 Performance Parts\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
