MEASURE DISTANCE BETWEEN REAR WHEEL CENTER AND REAR FENDER IN
DRIVING CONDITION
The measurement procedure is as follows:
1. The driver rides the motorcycle (the engine does not
start)
2. Up right the motorcycle so that the centre surface of
the tire is perpendicular to the ground
3. Measure the distance from the centre of the rear
wheel axle of the motorcycle to "point 1" and record it
as "A3".
4. The driver uses a single stand to support the vehicle
and leave the seat
Calculate the difference between "A1" and "A2" and
denote it as "D2".
The factory default value of "D2":
D2
GPX 50
～
100mm
If "D2" measured by the customer is lower
than the
factory value, you should decrease the spring preload
appropriately; Conversely, increase the spring preload.
If "D2" is far less than the factory value, replace the
spring with a softer one; Conversely, replace the spring
preload with a harder one.
ADJUSTING THE SPRING PRELOAD OF REAR SHOCK ABSORBER
adjuster
You can adjust the spring preload by adjuster.
Turn clockwise to increase spring preload,
Turn counter clockwise to decrease spring preload.
CHECK FOR THE SETTING OF FRONT SHOCK ABSORBER
The inspection procedure is as follows:
1. Place the whole motorcycle on the ground
2. Up right the vehicle
3. Hold the handlebars with both hands and press down on the front shock absorber
4. Observe the effect of pressure and rebound of front shock absorber
If it is difficult to press the front shock absorber, decrease the compression damping appropriately.
