The lack of space under the seat is my one complaint with the Tenere. I have an Autocom unit and Kenwood radio just sat in my garage doing nothing because I can't find enough room to fit it.

One option I am toying with is to look at mounting the comms stuff into a waterproof box on the back of the bike, possibly then mounting peatbog's excellent rack onto the top of that - this may be a pants idea though and may come to nothing. Will post if I ever get around to it being more than just an idea.
