In stock form, the suspension is set really tight and needed some tweaking to get the comfort level up a bit. Also with such a stiff setup in the first ride of the morning it was hard to keep the front of this machine on the ground. After talking with a couple other riders we decided to adjust the suspension on one machine while leaving the others stock and each of us took turns feeling how our changes helped or hurt the ride. It was apparent that after taking 4. 5 rounds of preload out of the rear shock and almost all the preload out of the front that we were getting somewhere. We then tweaked 1. 5 rounds of rebound out of the rear shock and with the fronts already being a one click away from the softest setting we took half of that away as well.
