That's right Dave, but I'm not taking it off the bike. For years, one of the things that's really annoyed me on long trips is stopping for a toilet break every couple of hours, so my new project will be building a toilet seat for a bike so that you can "do one's and two's, as you cruise".
I'm still at the "concept" phase, but considering that I'll be riding a water cooled bike, I'm sure I can modify the cooling system to allow a nice warm flush, and maybe a lovely jet of warm water to clean my privates? I'm guessing I can hide the cistern in the top box, and maybe convert those large panniers into water tanks, then just plumb the cooling hoses thru it to warm the water?
Oooer, I can just imagine it now, a combination of 2 of my favourite things, riding my bike, and taking a dump. Heaven........
