The spring preload setting of the shock absorber in the RX3 produces a very harsh ride. Fortunately, adjusting the spring preload allows this shock to perform much better.

Remove both saddles from the bike, and remove the black plastic panel which covers the battery on the right side of the bike.

To adjust the shock spring preload, you must raise the rear wheel from the ground to remove the bike's weight from the shock absorber. If you have a center stand, lift the bike onto it, and weight the front of the bike to raise the rear wheel from the ground.

I don't have a center stand. Therefore, I place the side stand of my RX3 on a brick, which almost raises the bike to a vertical position. I then turn the front wheel to the left, and place my Husky 3-Ton jack under the center stand support on the right side of the motorcycle. Pumping the jack lever raises the rear wheel off the ground, and places the bike in a very solid, secure position.
