Sprocket Locks
Sprocket locks help secure the front or rear sprocket to the engine output shaft or hub, preventing unwanted movement during riding. This category includes lock plates, retaining tabs, and fastening hardware used on ATVs, dirt bikes, pit bikes, scooters, and go-karts—especially models from TaoTao, Roketa, Coolster, and similar small-engine brands. A worn or missing sprocket lock can cause the sprocket to loosen, leading to poor power transfer or drivetrain damage. Replacing it ensures safer, more reliable operation.
