Actually as your body is bent in the seated position it is in mostly a straight line...British customs just responded to me on a Saturday and tells me the seat will fit a 2009 and with high quality leather so I just ordered one and it will take 4 to 5 weeks to build...I spent many miles in a seat shaped just like this and the back support was incredible for me...I am hoping this seat feels like that...after spending all the money we do on exhaust and other non rider comfort items, whats 600 for rider comfort...I will post a good review with photos after receiving my seat and my butt can't wait : ) ride safe!
