A handlegrip cruise assist device is formed of a single piece of stiff resilient material, having a circular segment which is shaped circularly so as to grip the outer end of the throttle handlegrip, and a lever segment which extends beneath the heel of the palm and adjoining wrist of the operator with his hand in the normal operating position on the throttle handlegrip. The application of downward pressure on the lever segment from the palm and the adjoining wrist of the throttle hand neutralizes the return force of the carburetor return-to-idle springs, permitting the operator to maintain a constant throttle opening without having to grasp the throttle handlegrip. The circular segment is of a diameter slightly less than the diameter of a complete circle. When mounted, the application of downward pressure on the lever segment of the device contracts the diameter of the circular segment to increase its grip upon the throttle handlegrip and assure that the relative rotational positions of the cruise control device and the throttle handlegrip remain the same. However, when upward pressure is applied to the lever segment, the diameter of the circular segment expands so as to loosen the grasp of the device on the throttle handlegrip, thereby permitting the relative position of the cruise control device and the throttle handlegrip to be rotated for release or adjustment of cruising position.
