I dont care for the spiked tank pads, they hurt. They were reccommended to me at the rally in May and I tried a Gixxer with them and even through my leathers they really messed with my inner thighs and hurt. Add to that I can see them tearing up your leathers over time pretty easy.
What I saw that Kelly was talking about was a hard plastic pad that sticks on the gas tank, right where the crease is on the upper portion of the 1098 tank, you can lock your knee up against it. I have read a few people love them, really give a good place to hook your leg on the tank. BUT, I havn't found a place to buy it yet, or who makes it. Everybody who has it got it from a friend, at a track, some random shop in the middle of oklahoma that doesnt have a phone number or before the internet was created
As far as the butt scratcher thing you be looking for, use some high density seat foam. If you look hard enough, you can find it a few inches thick and trim to your needs.
