Speedway Bike Explained:

CLUTCH ADJUSTMENT

The clutch is activated by a cable attached to clutch handle on the left side of the handlebars.

The cable is directly linked to the clutch mechanism with a spring load arm that releases the clutch plates upon final drive.

A cover is placed over this to reduce dust and contamination during racing.

The importance of this adjustment is cructial to getting the optimum start. Many wins are lost due to these bad starts.
