Some riders have the ability to go fast on any motorcycle, regardless of how the chassis is set up. For us mere mortals, this is one area that will require some work. I could write a whole book on this and some have already. This is a quick guide with general measurements to prepare you for the track. First you want to set the front and rear sag. This is the amount the suspension settles with the bike at rest and the rider and gear in place. Both front and rear sag should be anywhere from 7/8-inch to 1 1/8-inch. (22.2mm to 28.5mm) There are different ways to measure sag, but for first time purposes this will get you started.

Assemble three people (the rider and two helpers) and top out the rear suspension by lifting the rear of the bike until the shock is extended. Take a measurement from two fixed points, usually the rear axle and a mark on the tail section. Now have the rider, fully outfitted in the gear, sit on the bike in the racing position with one person holding the front of the bike. Bounce the suspension several times and take the measurement again. The difference between the two is the sag measurement. Adjust spring preload until you get the desired amount. Repeat the same steps at the front-end with the person holding the bike standing in the rear. Settings for the rebound damping and compression will vary on track conditions and rider preference.

Suspension setup is something that you just need to play with to understand. If you desire to learn about suspension, and don’t like to read like me, I suggest that you get the DVD called “suspension for mortals” You can order the DVD through Traxxion Dynamics. Just go to www.traxxion.com and place your order because you are not going to regret it.
