Description

The ETM RTR 63T Rear Sprocket is a direct OEM replacement sprocket for the ETM RTR 420 chain drivetrain. It maintains factory gearing for smooth, predictable power delivery across everyday riding and routine maintenance. The correct tooth count and chain compatibility mean no drivetrain modifications required.

Fitment:

  • ETM RTR XL

NOTE: This will work on Sport and Lite models using the Alpha motor and 420 chain system. You will need a different length chain from stock.

Rear sprockets wear down over time as they mesh with the chain under load. This 63-tooth replacement restores proper chain engagement, reduces unnecessary drivetrain wear, and brings back efficient power transfer to the rear wheel. Matching the original tooth count preserves the bike's intended gearing characteristics, keeping acceleration, throttle response, and overall ride feel consistent with factory spec. Whether you're replacing a damaged sprocket or performing scheduled drivetrain maintenance, this part delivers the correct fit without guesswork.
