mmmmmmmmm got me thinking too....
buy a cast iron ass cover.
I almost have all the bits I need.I cut the seat into sections to make shaping the foam a lot easier.I'm going to have 2 adjustable air pockets under the rider seat and gel pads front and back. Then a 1" section of foam over the top and reshape it back to how I want it.
take the train or a plane.
one of they wee hairy sheepskin covers.....i toured around france on my speed triple with not one sore arse....without the cover...ride about 20 mile...sore arse
