    GS850L seat de-hump before and after

    I've always disliked the seat on my L and after searching the forum, it seems that I'm not alone. There are plenty of threads asking about flattening the L seat, but not too many photos of modified seats.

    I picked up an extra seat on ebay that had a rusted pan, so I had a foam core to carve up. A kitchen bread knife and some 80 grit sand paper did the trick.

    A local upholstery shop sewed and installed vinyl cover, which came out nicely in my opinion. I can actually sit a little farther back on the bike now (I'm 6'4"). Glad I worked through this one.

                Good job! You made an "L" seat look just like a "non-L" seat....and it's more comfortable. Imagine that

                  With those bars and that seat mod, I would guess that even Tkent might give this L a thumbs up!

                  Well Done!

                      I did yesterday, guess I forgot to hit send or something. Nice DeLification!

                      Life is too short to ride an L.
