I'm not sure there is such a thing but you can set a chair up on a bike with bolt on mounting points (as opposed to welded on mounting points). There would then be nothing stopping you from leaving these on the bike and just unbolting the connecting arms from them along with a connector for the electrics.
You could then remove the mounting points when wanting to sell the bike on as a solo. Bear in mind though that, depending on the bike and size of the chair it's not unheard of to bend the bike frame slightly.
It wouldn't be a 5 minute job but not toooooo much hassle
Go to Scotia Sidecar website and look at their chairs by Tripteq for the GS and a few others. These are quickly added or removed but are not easy to store.
The biggest problem with this is setting up the chair properly. Each time you reattach it you'll need to readjust everything. Small adjustments can make big differences in the way the outfit rides.
This has been discussed in great detail in the hacks section of ADV rider site. Ask some questions here there are many guys who can give you much fuller answers.
The Tripteq is very popular in Europe,especially Germany and Netherlands. You could ask on this forum. Google will translate! http://forum.motorrad-gespanne.de/
