20L Modular Motorcycle Tail Bag & Backpack with Waterproof Liner

The Rhinowalk MT21620 20L modular motorcycle tail bag is one compact rear-seat bag that converts to a shoulder bag or backpack. Its removable welded inner liner protects contents from rain, while external buckles allow it to connect with compatible bags from the same modular family.

Fit and safety

Use a seat or rack that supports the bag footprint and provides stable anchor points. Keep every strap clear of the exhaust, wheel, chain and suspension, follow the vehicle or rack load limit and recheck tension during travel.
