Rear Shock Adjustment
Spring Adjustment:
Obtaining the correct rear spring preload is critical for
proper handling. The spring preload must be set to
match the weight of the rider. The spring is preloaded
for an 82 kg (180 lb) rider. This puts the rear tire 1/3
of the way through its vertical travel. Heavier riders
require stiffer spring rates. A good approximation of
your rear spring requirements can be found by
measuring the rear suspension’s sag. This
measurement will quickly determine if your rear
spring is approximately correct for your weight. This
adjustment is a recommended guideline; personal
riding preference may vary from the specifications
given.

Checking Sag
1. Support your motorcycle on a stand
with the rear wheel off the ground.
2. Measure vertically from the rear axle to
the rear fender. Mark this spot as it will
be used for other measurements.
3. Record this measurement, this will be
measurement M1.
4. Remove the motorcycle from the stand.
5. Wearing your normal riding apparel, sit
on the motorcycle.
6. Have an assistant hold the motorcycle
up, your feet should be on both pegs.
7. Bounce the suspension a couple of
times.
