To maximize the lifespan of your new sprocket and protect your engine's countershaft seals, always inspect your chain tension frequently and swap out your drive chain if it shows signs of stretching or stiff links.\u003c\/p\u003e\n\n\u003ch3\u003eRecommended Pairings:\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/search?q=KTM+50+SX+Parts\"\u003eShop KTM 50 SX Parts \u0026amp; Upgrades\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/search?q=420+Drive+Chain\"\u003eShop Premium 420 Motocross Drive Chains\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/search?q=Chain+Lube\"\u003eShop Premium High-Adhesion Chain Lubricants\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003ci\u003eMoto-House MX – Choice of Champions – Clermont \/ Montverde, FL.
