Willie & Max Black Jack Swingarm Bag 4.0 L – Black Buckle – Dual Shock

$101.99-15% OFF

Finally, a blacked-out, compact left side solo bag made specifically for sportster-style bikes with a smaller profile! We designed the Willie & Max Black Jack 4.0L Swingarm bag with bikes like the Honda Rebel in mind. The Black Jack 4.0L Swingarm Bag measures a trim 9.5in x 11.5in — these compact dimensions are ideal fit for smaller cruisers and sportster-style bikes like the Honda Rebel 500 or 300 or the Harley-Davidson Forty Eight, with plenty of capacity for wallet, keys, gloves, or sunglasses.

The all-black synthetic leather is UV-protectant and water resistant. Plastic backing and interior support keeps the bag in shape for miles and miles. The bag is a cinch to install with the included leather mounting straps.
Our matte black buckles are a perfect match for bikes with blacked out engine and frames. But don’t worry… the bag flap conceals quick-access buckles to get your stuff stowed fast. Additional side flaps help keep everything secure while you are out there putting on miles.
Like all of our Willie & Max Swingarm Bags, this model is designed and made right here in Manitowoc, Wisconsin, USA by our talented team of craftspeople.
