A drum stopper is a small but crucial component in the gear shift mechanism of many motorcycles, particularly older models and some modern classic-style bikes. It plays a vital role in ensuring smooth and accurate gear changes.
Here's a breakdown of the drum stopper's applications in motorcycles:
The drum stopper, also known as a shift drum detent or pawl, sits within the engine's gear shift drum. It acts like a small lock, engaging with notches on the drum to hold the selected gear in place. This prevents the gear lever from accidentally jumping out of position due to vibrations or rider input.
