【Limited Time Sale】 Thank you for viewing. The size is probably around 30ℓ or so. I used it to store a size L SHOEI helmet (X14). The helmet fits perfectly in the L size capacity. All accessories that came with the purchase are included. Everything in the photos will be sent. I have kept the items as they were when attached, so basically, you should be able to attach it to most carriers as is. - Brand: GIVI - Color: Black - Type: Top case - Design: Streamlined design - Features: Transparent front cover Thank you for viewing.
