The 312XL leather solo bag is specifically designed to fit the swing arm on many motorcycles, custom motorcycles and choppers. It is made to attach to the swing arm or the sideways V that comes off the axle nut with the provided leather belts. It comes with quick release buckles. The 312XL leather solo bag was designed for the left side of motorcycles unless there is a left side mounted license plate. It may also work on the right side if the pipes do not extend into the wheel well. If when you corner you tend to hit foot pegs, you will hit and damage this bag. The bag is customizable with our custom options. Please check the fitment guide before ordering.
