For someone who already has a Seat Concepts padding and cover setup, would you please measure the distance from the seam at the rear of the rider's section to the nose of the seat. I measured the oem seat at 13.5", and I tried a Sargent seat but felt cramped-I measured the Sargent at 13". FWIW I removed about 1" of foam from the front of the humpon the oem seat so I can slide my butt back, but I can already see that the stitching in the seam will not last very long w/o coming apart, so I am considering alternatives, but I will not accept being pushed forward into the gas tank. Second question: How slippery is the Seat Concepts cover? The Sargent was a little bit worse than the oem seat, not too bad with jeans, worse with riding overpants. The Corbin that the PO had on the bike when I bought it was like greased lightning.
