This is a superb bag, my Inazuma 250 has a SHAD top box but unless I'm off for an ultralight tour or fully expecting to need waterproofs I'd rather not use it. This bag can take my tubeless repair kit, disc lock, waterproof inners for my Weise Hydra jacket and trousers and it is just the right size, looks like a single seat hump when on, stays in place and looks decent.
