Thank you for viewing. This is a BMW MOTORRAD Adventure Collection seat bag. The capacity is 37ℓ, expandable to 45ℓ with a zipper. It's made of durable ballistic nylon. Includes straps, rain cover, and installation instructions. Although it's new, it was only test-fitted once on an R1200RS and has not been used for actual riding. The zipper area and bottom are also in good condition, but please understand that it is a used item and may have minor scratches due to the test fitting and storage. I am selling it because I am changing motorcycles. - Brand: BMW MOTORRAD - Color: Olive - Type: Seat bag - Included items: 6 straps in total, instruction manual
