Sena SC-A0354 Universal Helmet Clamp Kit for 50S 20S EVO 30K

SENA Universal Mount – Purpose Purchasing a new or additional mount is a good idea if the original mount is defective (for example, if the helmet fell and landed on the rack), or if you want to equip a second helmet with an additional mount. If you have multiple helmets with a built-in mount, the Bluetooth unit can be easily and conveniently swapped from helmet to helmet without having to constantly reassemble everything. Simply attach the Bluetooth unit to the desired helmet equipped with a mount and ride off.
