Installation is easy: remove your seat (5 minutes), remove the staples holding on your old cover, insert the foam and re-cover with the new ESR cover, then reinstall the seat (a complete installation video can be found on PowerMadd's website). The rider-forward design of the Rev was a great leap forward, but - as we all know - the seat level is just a little low which puts an unnecessary strain on your knees and back. The additional height eliminates knee and back fatigue and improves control by allowing you to stand more comfortably for powder or bad trails. The ESR (Ergonomic Seat Riser) kit takes you to the next level of comfort and control. Kits combines 1.5" of additional pre-cut foam with a gripper-style seat cover.
