two words memory foam, I have had bad expierence with memory foam, (two Words) fat bastard.
I was looking on the Sargents seats website, I have had one of there seats on an Z1000SX and it was a fantastic product. I think they are taking the piss now though for the seats for the FZ1 Main &Pillion £350.00 bugger that. I do know people who have used Tony Archer for seat mods, never heard a bad word said about him or his workmanship.
