UNDERSTANDING THE SUSPENSION GENERAL
Quick acceleration and the ability to go through the turns with power are the most important handling qualitiesThis section explains how the skid frame functions to provide these two important handling qualitiesBefore proceeding, however, note these termsWeight Transfer shift in the center of gravity in any direction depends on the force appliedTrack Tension The amount of tightness or looseness of the track when correctly mounted in the chassisSpring Tension The amount of force exerted on the spring by either fork tension adjustment or eyebolt adjustmentSki Pressure The amount of force exerted downward on the skisGood weight transfer characteristics are needed for fast acceleration (shift of weight from skis to track) and for cornering (shift of weight back to skis to hold the front end in turns)Effective weight transfer depends on suspension tension, position of rider, and the position of the front arm limiterTo understand how the suspension system works, think of the entire system in terms of three points; the skid frame rear axle center, the skid frame front arm, and the ski saddle centerAssume that the front arm functions as stationary pivot point between the rear axle center and the ski saddle centerAlso assume that the ski saddle center is the same height off the ground as the rear axle centerThis produces the standard position arrangement0728-181 0728-180
