Vortex 420 Aluminum Rear Sprocket for Honda Grom

Fine-tune your Honda Grom gearing with a lightweight Vortex 420 aluminum rear sprocket.

These sprockets are a strong choice for Grom riders looking for replacement gearing or a performance-oriented drivetrain setup.

Options: 33T, 34T, 35T, 36T and 37T. Confirm your Grom model year, chain pitch and desired gearing before ordering.

Gearing: More rear teeth generally increases acceleration; fewer rear teeth generally reduces engine RPM at a given road speed.
