I have a 2005 GS with ABS. I bought it used and have had it almost two years. The integrated ABS feels great except that the rear brake pedal feels squishy. It has always felt squishy. I can push the pedal all the way down and the servo sometimes shuts off. I know that I cannot lock up the tire using the rear brake pedal because of the ABS. On dirt it feels extremely bad like it is locking up and releasing if I hit it hard. I feel that when stopping on dirt, this is probably normal on the GS. Since I do a lot of off-roading, I would prefer to have ABS on the front wheel and no ABS on the rear wheel. Does anyone know if the squishiness is a normal feel? The only other GS I have ridden was a 2007 with non-servo-assist ABS so I have nothing similar to compare it to. If it isn't normal, do you think I can eliminate the ABS from the rear wheel and run it direct like a run-of-the-mill bike? Maybe it might be just a loose screw that I haven't found that I could tighten up.
