Abstract
A throttle control lever for a vehicle, and in particular for a recreational vehicle such as a snowmobile, has a two-stage lever action. In the first stage, which includes throttle openings corresponding to normal cruising speeds of the vehicle, the throttle lever turns about a first pivot axis wherein the mechanical advantage of the manual actuating force is relatively high. In a second range the throttle lever pivots about a second pivot axis wherein the mechanical advantage of the manual actuating force is relatively much smaller. Operator fatigue is reduced because of the reduction in force required at normal cruising speeds of the vehicle.
