REAR SUSPENSION REGULATION
The rear suspension, is equipped with a swingarm and a central shock absorber
pneumatic, adjustable in load and preload, and with hydraulic regulation.
Preload
The regulation of the shock preload is made by combining the pressures of the upper
chamber, of the main pressure and of the lower chamber, of negative pressure.
Taking into account that the increase of the pressure in the upper chamber will
increase the hardness of the shock absorber. And that the increase in pressure in
the lower chamber increases the preload of the shock absorber.
The pressure variations of both chambers must always be combined. The recommended
reference values are the following:
User weight (kg)
Upper chamber (bar)
Lower chamber (bar)
50
6,2
3,5
60
7,2
3,5
70
8,3
3,8
80
9,3
4,5
90
10,3
4,8
100
11,4
5,2
To determine the correct pressure settings, it must be taken into
account that in no case should the rear shock absorber stop at its
end of travel.
Hydraulic
The regulation of the hydraulics is endow of a double control, located in the upper
part of the shock absorber.
The blue knob has three positions; open, medium and blocking. This command is of
macro-regulation. The blocking position is only used when the user is driving through
terrain without irregularities.
The red knob only acts in the intermediate position. Turning the knob clockwise
decreases the speed of return of the suspension, closing the hydraulic passage.
