My 2 cents on this seat thing? I think the manufacturers are catching up with Corbin and that the Busa seat is one of the best OE sport bike seats yet. It takes a lot of lessons from Corbin. It's flat, wide, soft-padded, shaped to human anatomy in the plan view (it could use a little cupping like Corbin does), and is covered with rough material so you don't slide around unwillingly.
I don't believe the Corbin seat's going to prove to be much an improvement over this one, if any.
And Corbin still wants the same old prices as he did in 1990!
To me, Corbin seats and their phony vinyl pressed pattern and piping look like old technology...more at home on a V-Max than a Busa.
Corbin seats were outstandingly better than OE in their time, and he's now making (or at least selling) ground-breaking luggage in his Beetle Bags (check his site).
I'd like to see him put his creative design and engineering skills to use on some new, more improveable aspects of bikes...like wind screens, bars, pegs, passenger rests, lighting packages....
Am I talking sacrilege here?
