Description
A worn or damaged front sprocket directly impacts your bike’s acceleration, chain wear, and overall drivetrain efficiency. The Renthal Front Grooved 13-Tooth 428 Chain Sprocket delivers the durability and lightweight performance needed to maintain consistent power delivery while reducing unsprung weight that affects handling. If you’re running hard off-road or pushing your bike to its limits, this CNC-machined component ensures your countershaft stays reliable across demanding terrain.
Renthal engineered this sprocket with 655M13 nickel chromium steel—a case-hardened, core-refined material that resists tooth wear and fatigue better than standard steel. The self-cleaning mud grooves machined into each tooth prevent debris buildup, a critical feature in off-road conditions where mud, sand, and rocks can accelerate wear. Combined with a 10-15% weight savings over conventional designs, this sprocket improves both throttle response and handling characteristics without sacrificing strength.
Installation is straightforward on compatible Gas Gas, Husqvarna, and KTM platforms—simply verify fitment against your specific model before ordering. Manufactured to tight tolerances, this component integrates seamlessly with your existing 428 chain for optimal meshing and longevity.
