UNDERSTANDING THE SUSPENSION

GENERAL

Quick acceleration and the ability to go through the

turns with power are the most important handling

qualities. This section explains how the skid frame

functions to provide these two important handling

qualities. Before proceeding, however, note these

terms.

Weight Transfer — A shift in the center of gravity

in any direction depends on the force applied.

Track Tension — The amount of tightness or loose-

ness of the track when correctly mounted in the

chassis.

Spring Tension — The amount of force exerted on

the spring by either fork tension adjustment or eye-

bolt adjustment.

Ski Pressure — The amount of force exerted down-

ward on the skis.

Good 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 trans-

fer depends on suspension tension, position of rider,

and the position of the front arm limiter.

To 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 center.

Assume that the front arm functions as a stationary

pivot point between the rear axle center and the ski

saddle center. Also assume that the ski saddle center

is the same height off the ground as the rear axle

center. This produces the standard position arrange-

ment.

0728-180

Under acceleration when the center of gravity is

transferred to the rear of the machine, the rear sus-

pension collapses slightly. This brings the rear arm

point downward and with the front arm stationary,

the teeter-totter effect reduces the pressure on the

skis, position A.

However, for controlled cornering, more pressure is

needed on the skis. So when the driver decelerates

coming into a corner, the center of gravity is trans-

ferred forward, putting the required pressure onto

the skis and reducing the pressure on the rear sus-

pension, position C.

0728-181

This is essentially what weight transfer is all about

— the shift of weight to the rear of the machine for

positive traction and good acceleration or to the

front of the machine for positive handling and cor-

nering control.
