I took the basic steps fom shortyR6 on this forum and adapted them to fit. Someone on the thread suggested that, instead of shaving from the top of the seat, we could try shaving from the bottom of the foam in order to preserve the stock seat look. I'm 5'6" and ended up lowering my seating position about 1" or so.
Tools required:
Staple gun with 1/4" staples, 3M Super 77 spray adhesive, needle-nosed pliers, small flathead screwdriver, hex wrench (in tool kit), box cutter, and sharpie:
Pull back at the rear of the seat and uncover the two hex bolts keeping the seat in place. Remove with hex wrench.
Looking at the bottom of the seat, you'll see that the fabric covering the foam and plastic is kept in place with staples. I used a sharpie to mark the fabric and plastic for re-alignment purposes.
Take your small screwdrievr and gently ply under each staple to loosen it, taking care not to rip the fabric.
Use the needle-nosed pliers to grab each staple and pull them free.
Once you get all the staples, your seat will be cold and naked:
Gently pry the foam apart from the plastic tray... it is held in place by dried spray adhesive all around the edge of the plastic.
At this point, I put the seat back on the bike and used the sharpie to outline the area I wanted lowered.
I used the box cutter, with the blade at full extension, and cut around the outline I made, scoring peelable chunks as I went along. The first pass yielded chunks about 1" thick.
Test fitting the foam and plastic back on the bike, I felt that it was still too tall and the area around my thighs could stand some thinning, so I scored and peeled a little more until it felt right.
Take the 3M Super 77 and spray the plastic tray with a thin coat of adhesive.
Carefully fit the plastic tray on top of the backside of your foam seat... the stuff is super-tacky, so work accurately... it'll peel off if you make a mistake, but do it right the first time and you'll be better off.
Fit the cover back on (it should fit exactly as you took it off... no stretching necessary). Use your sharpie marks to keep things aligned correctly and staple the fabric back into place.
Finished seat:
Shaved seat reinstalled:
The seat looks stock and the only way you can tell that anything was done is when you sit on it. There is still at least 1" of foam left where it counts and still pretty cushy for me.
