I got new seat foam (softer--my butt still hurts from the last enduro) and a new seat cover from E.E. My question is: any trick to installing the new foam and cover on the seat pan? Several friends have replaced their KTM seats, but have had upholstery shops put 'em together. It's not that I'm cheap (I am), I just think it looks like something less than rocket science to do this, and it will give my riding buddies something (else) to razz me about if I screw it up.
