The sporty sack is the perfect bag for every Sportster. Its nice to have somewhere to store some tools, your paperwork, and a small jacket, whatever it may be. The design of this bag is big enough for storage but small enough to maintain the look of the bike. The sporty sack can be mounted in 2 ways, you can use the adjustable leather straps to attach around the fender strut or the stationary straps with grommets attached to the fender strut bolts. The bag will fit 1957-Up Sportster applications. We have left, and right side available to order.
