well almost dirt bike posture. I put foam under eat skin, isnt  quite right yet but mroe confortable than stock and I sit higher which I wanted. Stil have to lower the pegs a bit. I also have bar risers, they put bar up and back maybe 1.5 inches. I rotated bars so they are high.

I sit high on what feels like a narrow bike now with those wide OEM handlebars up high. Its is very confortable, kind of wierd though. Probably get superbars during snow season and the seat foam is interesting process..

You could look in the wiki for that mod with the gsxr pegs from ebay. They're easy to install and drop the peg height about an inch. You don't loose any peg clearance either because the pegs aren't any lower than stock, they're just MUCH thinner.

I don't know much about the dirtbike posture, never really been on one. My first bike was an 83 dual sport, so I remember that bike, but I don't know how much like a dirtbike I really was. I do however remember feeling like I was going to die the first time I went 85mph. I wish I had kept that bike. I sold it for $200 to my cousin.

I love riding the dirt bikeposition.  learned on little honda 50 and learned clutched bikes on a xr80.  I got some universal dirt bars on my 97' 500E, put em in the stock risers and love em. The grips are only foward about an inch and a half more which i thought they would have me leaning foward alot more than that so its great that im not. And the added width and less angle feels so much better than stock. For a dirt bike lover anyway.  never even thought about adding to the seat to make it higher. sounds like something id wanna try. but i dont wanna tear my seat vinal off then not be able to put it back on cleanly.  I might find something to put on top of it though.  Do you have any pics of your seat and bars though?

Recovering a seat is pretty straightforward if you have a staple gun and some patience. Probably easier with new cover material (if it's good stretchy stuff) than old sunbaked material. You can get about 3 GS seat covers from a yard of 54 inch wide "all-sport" 4-way stretch upholstery. Two if you are sloppy.

I added 2 inches (less when I sit on it, of course, despite claiming to be "extra-firm") to my seat when I replaced the ripped cover that came on it. Helps quite a bit for my preferences. I also extended either 1/2 inch or an inch (using 1/2 inch foam, don't remember if it was one or two layers back there) over the pillon area. Forgot my camera that day, decided to get the job done rather than worry about making more pictures of a process that's pretty well documented on the web in general. I did start with recovering a bicycle seat, which was much more of a pain than doing the GS seat was, so that made it "easier"  - and now they match (well, the seats do - perhaps the paint will one day, too).

Its not ready for photos i.e. its not right yet. I will snap some anyway next time up in the NH mountains where bike sits. Had nice ride last Sunday. Roads deserted, half warm day, sunny and pretty.

Seat foam on extra seat went easy first try, bought the golds gym mat at Wally World, applied a few layers to the extra seat after removing the cover, the foam had been cut down for short leg rider, all looked fine until I put cover back on. It revels lack of perfect surface on layers of mat.

I smoothed with belt sander, as each layer went on one at a time and it has lumpy ugly appearance once the cover is on. Cover is very revealing of flaws in the foam application.

I will redo, and put on many layers at once, then cut to butt form once with belt sander, it should come out smoother.

The golds gym mat is kind of firm. Not sure its perfect. It feels a lot better though.

Basic Arrow stapler will put 1/4 inch staples though the cover material and seat base if held firm against the base. Any misalignment / slop and it wont go through, it just bounces and misfires.

Electric Stapler might be better but spring loaded suffices.

The bars are boring mod, just back and up. It is more comfortable for the mild riding I do. They are high and back enough thats its slightly unstable at low speeds with tight turns over bumpy ground or tight unpaved down or uphill driveway turns.
