Kuryakyn 6315 XL Universal Throttle Boss provides a wider palm rest than the original 6251 Throttle Boss. Simply wrap this soft rubber hand-rest device around any twist throttle grip, position it for the right cruising speed and enjoy a cramp-free ride on those long stretches of road.
Throttle Boss is made from a soft and durable synthetic rubber. Taking it off or placing it on the grip takes seconds.
Fits any size twist throttle grip.
