24 Ranger - OWNER‘S MANUAL
3 Pull and hold the brake lever firmly for the caliper to get centered with the brake disc
and re-tighten the caliper fixing bolts (9,5 - 10,5 Nm), then release the brake lever.
4 Test the brake by pulling hard on the lever a number of times.
5 If the wheel does not spin freely with the brake lever released, the caliper position
itself needs to be fine adjusted again repeating the steps 1 to 3. Remember that the
new brake pads are thicker and need to break-in first.
Brake squeal
Dirt and humidity can cause noisy or squealing brakes. These are normally temporary and
should gradually disappear with regular use. Repair is not required. If you hear a metallic
“screeching” sound you might need to replace the brake pads. Visit your KUBERG dealer to
replace the brake pads.
Adjusting the suspension
The KUBERG Ranger features both front and rear suspension.
Front suspension
The front suspension on your KUBERG Ranger is adjustable, the RST KILLAH front fork
has settings for damping.

Set up notes
Recommended air pressure 50–90 psi [3.4–6.2 Bar]
Max pressure not to exceed 110 psi [7.58 Bar]
The fork should be unweighted when
adjusting air pressure
Static Sag should be 25–35 % of travel
See owners manual for sag measurement procedure
All damper adjustment positions are taken from full-
closed/clockwise (Position 0 = Maximum damping)

Tuning tips
For best performance it’s im-
portant to balance the rebound
damping in the front fork and
rear shock; front and rear wheels
should return at the same speed.
If fork is losing travel in repeated
impact situation eg. (rocky
terrain) reduce the rebound
damping)
Controls the speed at which wheel
returns to sagged position after
compression event.

Tuning tips
Turning the High Speed adjuster
knob will not change the TPC+
Adjustment. Although it follows the
rotation of the HS knob, the TPC+
Adjuster must be turned inde-
pendently from High-Speed Adjust-
er to change the TPC+ setting.
If fork is losing travel with repeated
impacts, increase the High-Speed
Damping.
If the fork is still diving with the High
Speed adjuster fully closed, the
TPC+ adjuster may be increased to
compensate.
Controls the damping force for short
travel unsprung wheel movement;
roots, rocks, braking bumps, etc.

Tuning tips
If fork is bottoming frequently,
try increasing TPC+ Damping
before diverting from recom-
mended air spring pressure.
If fork is “spiking” mid-travel,
decrease TPC+ Damping, or
increase High-Speed Damping
to smooth the transition.
Controls the damping force
for deep travel sprung chassis
movement; jumps, drops, etc.
