Vortex 420 Front Sprocket for Honda Grom

Upgrade or change the gearing on your Honda Grom with a Vortex 420 steel front sprocket.

Vortex front sprockets are induction-hardened steel with corrosion-resistant plating and are manufactured for consistent chain engagement.

Fitment: Honda Grom / MSX125 applications using the 420 drivetrain. Available in 14T, 15T and 16T gearing options. Confirm model-year fitment before ordering.

Gearing: A smaller front sprocket generally increases acceleration while a larger front sprocket generally lowers cruising RPM.
