Moose Racing 12-Tooth Front Sprocket for Yamaha (D26-4168-12CRMO)

Upgrade your Yamaha drivetrain with the Moose Offroad D26-4168-12CRMO 12-tooth front sprocket, engineered for dependable performance in demanding two-wheel dirt, adventure, and ATV applications. The sprocket is machined from high-tensile-strength chromoly steel that resists impact, wear, and deformation, helping maintain reliable engagement under heavy driveline loads.
The inner splines are broached for precise fitment and maximum contact with the countershaft. This design distributes driveline forces across a broad surface area, supporting smooth power transfer and reducing concentrated stress on the mating components. The sprocket is heat-treated for added strength and durability, then finished with a nickel coating that helps resist corrosion while providing lubricity during operation.
Every Moose Offroad D26-4168-12CRMO sprocket is quality checked using a Computer Measurement Machine (CMM) to closely match OEM design specifications. This attention to manufacturing accuracy helps provide consistent fit and dependable service when replacing a worn or damaged front sprocket. The 12-tooth configuration can also affect gearing and chain clearance, so verify your Yamaha application and inspect surrounding components before installation.
Designed for select Yamaha dirt bike, ADV, and ATV applications, this front sprocket is a practical replacement for riders who need durable drivetrain components for off-road use. When ordering a sprocket larger than the stock size, be sure to check for adequate clearance around the chain, case, and related components. Confirm vehicle fitment, chain compatibility, and gearing requirements before purchase.
