I just listed an RXL on ebay, I rode it twice, I really liked the dent area, but the seat is flat and does not flex at all to me. It really puts you into a position and supports very well in the seat, I just like to be able to move around a little more. It is very close to the SSM glamour when you compare the two. The RXL seemed a little more padded than the glamour. If it had a little more of that scooped seat that the glamour has I would have kept it forever.
