OK I think I have come to the decision that I want the single seat with rack setup for my Scrambler. My question is this. I want to be able to have a hard storage box that attaches to the rack, but I want it to me easily removable and quickly. I use the bike for various purposes but don't always need or want the hard box attached. I want the box to be able to be put on and taken off quickly and frequently. Is there some kind of quick release bracket system for a hard box that will fit on the single seat with rack for the Scrambler? Any help would be appreciated. Thanks.
Any of the Givi Monolock range of cases will do what you want. They all include an adapter plate to add to an existing luggage rack. I have mine on a Renntec rack, but it should work for the solo seat rack as well.
here it is on ebay
It's a roomy case, oughta hold two helmets. It has a quick release, and a monokey system. The plate stays on the rack. The tank bag is a Joe Rocket Manta.
