Description
Get your electric scooter or mini-chopper back in motion with the Universal Parts 11-Tooth Front Motor Sprocket. Designed for MY1016/MY1020-style small electric motors, this sprocket features a "Double-D" bore with two flat sides for a non-slip, keyed fit on the motor shaft. Precision-cut teeth ensure smooth #25 chain engagement and quiet, reliable power transfer.
Key Features
- Double-D Bore: Two flat sides (8.6mm apart) lock onto the motor shaft, preventing free-spinning under load.

- #25 / #25H Chain Compatible: Fits the most common drive chain size used in electric powersports.
- Heat-Treated Steel: Resists tooth hooking and wear even with frequent stop-and-go use.
