Does your throttle hand get tired on longer rides? This two-piece throttle-assist set adds a broad palm-contact paddle over the motorcycle’s twist throttle, so the rider can apply pressure with the heel of the hand instead of gripping as tightly. Product photos show the textured pieces fitted around a throttle grip.

It is a throttle aid, not cruise control: it does not hold a set speed or replace active throttle control. Check that the piece fits your grip and does not obstruct the brake lever or prevent the throttle from returning freely before riding.
