This Trunk Base is required for the installation of an accessory Quick Release Touring Trunk or Quick Release Low Profile Trunk on a Challenger model. This base mounts directly on the trunk and features Quick Release technology so riders can quickly remove or add their trunk in seconds without tools. Quick Release technology makes it easy to change the look and function of your motorcycle - leave your trunk at home for a day trip or add your trunk when you need more luggage capacity. This trunk base is made from durable steel, and it’s available in either chrome or black to perfectly match your motorcycle.
