This is the SHAD tank bag E03CL. It uses a click system, making it easy and convenient to attach and detach from your motorcycle. Also, it's a key-lock type, which is effective against theft of the tank bag itself. Please see the SHAD official page for details. Please refer to the images for the product condition. Thank you. I am also selling this item elsewhere. If the item is out of stock due to my being asleep or away, and I am unaware, I may have to cancel the transaction. Thank you for your understanding.
