Precision CNC-machined from case-hardened and core-refined 655M13 nickel-chromium steel, this sprocket offers the perfect balance of strength and longevity to withstand the rigors of competitive motocross.\u003c\/p\u003e\n\u003cp\u003eWhat sets this sprocket apart is its advanced \u003cstrong\u003eself-cleaning mud groove\u003c\/strong\u003e design. By machining these grooves at the base of each tooth, Renthal effectively prevents mud and debris buildup, which significantly increases the wear resistance of both your chain and sprocket. The ultralight design delivers a 10-15% weight savings compared to stock components, reducing rotating mass for improved acceleration.\u003c\/p\u003e\n\u003ch3\u003eTop Features: Renthal Grooved Front Sprocket\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCNC-machined from high-strength 655M13 nickel-chromium steel\u003c\/li\u003e\n\u003cli\u003eFeatures self-cleaning mud grooves to reduce debris buildup and increase lifespan\u003c\/li\u003e\n\u003cli\u003eUltralight design reduces rotating mass by 10-15% for better performance\u003c\/li\u003e\n\u003cli\u003eCase-hardened and core-refined for maximum wear resistance\u003c\/li\u003e\n\u003cli\u003eEngineered specifically for the KTM 65 SX 420 chain drive system\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003ePlease review the detailed compatibility data below to ensure an exact fitment match for your motorcycle before finalizing your purchase.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch2\u003eFitment List\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; border: 1px solid #e0e0e0; margin-top: 15px; margin-bottom: 15px;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #f7f7f7;\"\u003e\n\u003cth style=\"border: 1px solid #e0e0e0; padding: 12px; text-align: left; font-weight: bold; color: #333333;\"\u003eYear Range\u003c\/th\u003e\n\u003cth style=\"border: 1px solid #e0e0e0; padding: 12px; text-align: left; font-weight: bold; color: #333333;\"\u003eVehicle Brand\u003c\/th\u003e\n\u003cth style=\"border: 1px solid #e0e0e0; padding: 12px; text-align: left; font-weight: bold; color: #333333;\"\u003eVehicle Model \u0026amp; Sub-Model\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e1998-2009\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKTM\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e65 SX\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why choose a grooved sprocket over a standard one?\u003c\/strong\u003e\u003cbr\u003eA: The grooves are engineered to evacuate mud and dirt from the root of the tooth. In wet or muddy conditions, a standard sprocket can get packed with debris, causing the chain to \"climb\" the teeth and wear out prematurely. The Renthal GP design keeps your drive system clean and efficient.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does the lighter weight really make a difference?\u003c\/strong\u003e\u003cbr\u003eA: Absolutely. Reducing rotating mass at the countershaft sprocket helps the engine spin up faster, giving you better throttle response and improved acceleration off the starting gate.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e Never install a new sprocket with a worn, stretched chain. Doing so will cause the new sprocket teeth to hook and wear out within just a few hours of riding. Always replace your chain and sprockets as a complete set to ensure maximum life and smooth power transfer to the rear wheel.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/ktm-65-sx-performance-upgrades-engine-mods-accessories-moto-house-mx\"\u003eKTM 65 SX Performance Parts\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/mx-off-road-chains\"\u003eHigh-Performance MX Chains\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/mx-off-road-motorcycle-tools\"\u003eBrake \u0026amp; Drivetrain Service Tools\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
