ABSTRACT:
A finger throttle for motorized vehicles having thumb throttles with thumb operated levers. The finger throttle includes a housing, a linkage assembly, and a finger operated lever. The housing is configured to mount on the thumb throttle housing and the linkage assembly is configured to engage the thumb throttle linkage assembly. The finger operated lever is linked to the linkage assembly such that moving the finger operated lever moves the linkage assembly, which in turn moves the thumb throttle linkage assembly. The operator can use the finger operated lever or the thumb operated lever to control the engine speed or can use both levers concurrently to do so.
