Product Info

The Electro & Co ETM RTR 420 Chain 55T Rear Sprocket is a direct OEM replacement built for 420 chain drivetrains. It covers routine drivetrain maintenance and worn sprocket swaps across ETM RTR models. Factory tooth count and OEM-spec fitment mean no tuning changes, no guesswork, and clean chain engagement from the first ride.

Fitment:

  • ETM RTR

This 55-tooth rear sprocket is precision-matched to the ETM RTR's original gearing setup. The factory tooth count keeps acceleration predictable and power delivery consistent, so you're not chasing drivetrain behavior after a maintenance swap. Built to OEM spec, it seats correctly and engages cleanly without requiring any modifications. Whether you're refreshing a high-mileage drivetrain or keeping a spare on hand before a long riding season, this sprocket restores your bike's drivetrain to the way it was designed to run.
