For example, if you want the medium power mode, hold the control button for two
beeps and release. The motorcycle will confirm your selection with a double beep.

The power mode is now set. If you want to set a different power mode level, repeat
the process from step 1.
CAUTION!
Sport and Race modes should only be used by experienced riders!
Drivetrain
Your KUBERG Challenger features a traditional chain and sprockets. It has a direct drive
with no gears. The chain does not need to be adjusted on a regular basis, especially
when the motorcycle is new.
However, it is important to check the chain before every ride and adjust it when
necessary. There should be only a very little slack in the chain.
Adjusting chain tension
Follow these steps to adjust the chain tension:
1
Ensure the power is turned OFF.
2
Lift the motorcycle onto a block or stand so that both wheels are off the ground.
3
Using the Allen wrench #10 and the open wrench #24 loosen the rear axle nut.
4
Turn the adjustment eccentres evenly on both sides. Very small movements make a
big difference. Do not tighten the chain too much so that there is no slack at all. It
should be ‘taught’, not ‘tight’.
5
Tighten the rear axle nut (78 - 80 Nm), check the sprocket and chain tensioner for
tightness and ensure all bolts are tight.
6
When turning the rear wheel by hand, lubricate the chain with the off-road
motorcycle chain lube spray.
7
Spin the rear wheel by hand at least 10 times more around and wait a few minutes for
a spray to dry off.
8
Remove the excess lubricant using a cloth. If the wheel does not spin freely,
go to
page 21
and follow the brake adjustment instructions.
9
Check once more the rear wheel for alignment and the chain for tension.
WARNING!
Failure to maintain and adjust the chain and align the wheel correctly could result in
the chain jumping off the sprockets, causing a potentially dangerous and damaging
situation.
Motor performance
The KUBERG Challenger has multiple sensors and control software to prevent the
batteries, the motor and the controller from overheating. Once the temperature of
batteries, motor or controller reaches a high temperature, the motorcycle power will be
