Got my Seat Concepts on today. Installed at a local upholstery shop, $20, 20 minutes, ride in with stock seat, ride out with "new" seat. So far, so good with only a couple of 30-minute commutes. Now my seat is a little wider than my butt and the annoying forward slope is gone. I had the stock seat tilt modified, still wasn't "level" enough. The Seat Concepts seat is mounted as OEM and I don't feel the need to tilt it up in the front. The standard perforated seat top material is not as grippy as stock. I'm neither here nor there about that. The foam feels harder, not too hard and I expect it will soften as it heats on longer rides, in warmer temperatures, and/or breaks in. I weigh about 185 dressed to ride.
