MOOSE RACING Front Sprocket - 15 Tooth - Yamaha 26-4163-15CRMO

A worn or undersized front sprocket directly impacts your bike's acceleration, chain engagement, and overall drivetrain efficiency. The MOOSE RACING 15-tooth front sprocket replaces inferior OEM components with precision-engineered chromoly steel that resists wear and deformation under aggressive riding conditions. If you're running stock gearing or experiencing chain slippage, this upgrade delivers the durability and performance your bike demands.

Built to strict OEM specifications and validated with computer measurement equipment, this sprocket features broached inner splines for perfect countershaft contact—eliminating play that compromises power delivery. The heat-treated, nickel-coated finish resists corrosion and provides superior lubricity, extending drivetrain life in wet or abrasive off-road environments. Bolt-on installation requires no fabrication, making it an ideal upgrade for riders seeking reliable gearing without complexity.
