E-Ride Pro - Pro S / SS 2.0 - OEM Drive Sprocket

SHE7888 is E Ride Pro’s factory 55-tooth rear sprocket for the 420 chain drivetrain on the Pro S and SS 2.0. The rear sprocket is where the chain turns the wheel. As it wears, the teeth hook over and thin out at the tips, which chews up the chain, causes skipping under hard throttle, and makes the drivetrain noisier. That’s why riders usually replace the sprocket and chain together. A worn sprocket will wear out a new chain quickly, and a stretched chain does the same to a new sprocket. The 55-tooth count is also a useful gearing tool. Going up in teeth from a smaller sprocket gives more pull out of corners and up climbs, while going down from a larger one adds top speed. This sprocket uses the factory bolt pattern and 420 pitch, so it runs on the stock 112-link chain. It’s not for the SS 3.0 or SR, which use 428 chain.
