Good To Know
Q: How is the thumb throttle control lever installed? A: Remove the old lever assembly and mounting hardware, then position the replacement lever against the handlebar and secure it before connecting the throttle cable.
Q: Why does my thumb throttle lever feel stiff? A: A stiff thumb throttle control lever can result from a worn return spring or a cable needing lubrication. Check the cable and pivot before installing a replacement lever.
