Frequently Asked Questions
Which bikes does this fit?
This OEM 420 front sprocket fits the ETM RTR Sport, ETM RTR Alpha and ETM RTR XL.
Will it work on an RTR that uses #35 chain?
No. This is a 420 sprocket for the RTR Sport, Alpha and XL 420 drivetrain.
Is this the front or rear sprocket?
This is the front sprocket that mounts on the motor. For rear sprockets, see ETM RTR 420 Sprockets.
Should I replace the chain at the same time?
It is a good idea, since chains and sprockets wear together. The ETM RTR 420 Replacement Chain and Sprocket Kit includes front and rear sprockets plus chain.
How many teeth does this sprocket have?
It is an 8 tooth (8T) 420 sprocket, the same front sprocket used in the ETM RTR 420 Replacement Chain and Sprocket Kit.
