MOOSE RACING Front Sprocket - 12 Tooth - KX450F/X D26-2153-12CRMO

A worn or undersized front sprocket directly impacts acceleration response and overall drivetrain efficiency on your KX450F/X. The MOOSE RACING 12-tooth front sprocket delivers precise engagement with your countershaft while resisting the impact loads that come with aggressive riding and racing. This is a critical wear item that demands OEM-level quality and dimensional accuracy—exactly what you get here.

Engineered from high-tensile chromoly steel, this sprocket is built to withstand the punishment of competitive riding while maintaining consistent performance across hundreds of hours of use. The broached inner splines distribute driveline forces across the maximum contact area, reducing stress concentration and extending service life. With a nickel coating for corrosion resistance and factory-verified CMM inspection, you're getting the same precision MOOSE Racing delivers to professional race teams.
