A WORD ABOUT THIS SAFETY MANUAL
DEAR KUBERG CUSTOMER,
Congratulations on your purchase of a KUBERG X-Force Pro 50. You now own a state of the art
electric motorcycle that will give you endless thrills if you maintain it properly. We welcome you
to the community of KUBERG riders.
Your KUBERG X-Force Pro 50 is a performance motorcycle that should be treated with caution
and used in safe environments. As the owner of this motorcycle, it is your responsibility for
the safety of the rider at all times. If you defer this task to another adult, you need to pass this
owner’s manual and all relevant information to whoever will take on this role, and ensure without
question that the rider is controlled and taught in a safe manner.
Your KUBERG motorcycle is highly adjustable and can be set up specically for the rider.
Please do not allow the bike to be used or adjusted by other operators.
Your KUBERG motorcycle is driven by a powerful electric motor, which requires experience and
careful handling. The speed and torque settings MUST be set to suit the abilities of the rider.
Please remember that even when the torque setting is set to a slow setting, the torque on these
motors is virtually instant. This means that opening the throttle will propel the motorcycle to
a rapid speed almost instantly. For developing good riding skills this is a wonderful feature, as it
will teach riders throttle control gradually with lower power. If the maximum power and torque
is set too aggressively, the rider may accelerate to a speed he/she is not comfortable with. Your
X-Force Pro 50 has great capabilities, and can grow with the skills of the rider to very high levels
of performance, but it is IMPERATIVE that the responsible adult controls the entire learning
process and pays full attention at all times. You need to foresee all potential situations and
manage the riding environment and the rider accordingly.
KUBERG motorcycles are designed for o-road use only and must not be used on public roads
or sidewalks. Please check and obey all local and state laws. KUBERG motorcycles should only be
ridden in safe areas where all laws are being followed and all required permissions are given.
KUBERG motorcycles are amazingly capable, and can be used from the earliest stages of learning
to ride all the way through to veteran riders. The secret of learning to ride well is being able to
ride a lot, and KUBERG motorcycles make this learning process very gratifying.
Thanks again for purchasing a KUBERG motorcycle, and we hope you enjoy the ride!

OWNER’S MANUAL 2017
SAFETY ADVICE
WARNING!
Failure to obey all of the warnings and instructions contained in this manual may result in serious
injury or death and/or permanent damage to your KUBERG motorcycle.
SPEED & TORQUE SETTINGS
Your KUBERG X-Force Pro 50 features a power and torque control button that must be set for the
abilities of the rider. This must be set by the responsible supervising adult before each and every
ride. Instructing and practicing in a controlled situation will allow the rider to learn how to operate
the motorcycle safely. Go to page 16 to nd detailed instructions how to set up the dierent
speed and torque modes.
WARNING: ADULT SUPERVISION REQUIRED
This vehicle must be used in the presence of adult supervision to ensure that safe riding practices
are established and followed. A parent should supervise their child’s operation of this vehicle at all
times. Parents should permit continued use of this vehicle only if they determine that their child
has the ability and judgment to operate the vehicle safely.
WARNING: OFF-ROAD USE ONLY
KUBERG motorcycles are designed primarily for OFF-ROAD use. Please check your local, state and
national regulations as to whether single–track, motorized electric vehicles are legal for road use
in your area. KUBERG X-Force Pro 50 is not approved for road use in the European Union.
ELECTRIC DRIVETRAIN
The fully electric drivetrain of this motorcycle diers from gasoline motorcycles, in that:
1There is very little engine braking and no engine noise.
2When going into corners or coming to a stop the rider will be fully dependent on the bike’s
brakes.
3Passers-by may not hear you approaching, so extra caution should be taken. Make yourself
conspicuous to reduce the chance of others being unaware of your presence.
4Be aware that your motorcycle is still ON when stopped and while at an ‘idle’. Accidentally
twisting the throttle can cause serious harm.
SAFE RIDING PRACTICES
1OPERATOR ONLY! No passengers!
2Long hair, loose clothing or items worn by the rider must be covered to prevent entangle-
ment in moving parts of the vehicle or the surroundings whilst riding.
3 Do not exceed the weight limit. Heavier riders may signicantly reduce performance and/or
render the vehicle unstable and/or over-tax the brakes and other control devices. Heavier
riders may cause structural damage not covered by the warranty.

7
4Do not touch any moving or hot parts.
5DO NOT RIDE AT NIGHT OR UNDER LOW VISIBILITY CONDITIONS. The KUBERG X-Force Pro
50 is not equipped with lights.
6Do not immerse this vehicle in water.
7Do not ride on steep or uneven surfaces. Steep or uneven surfaces greatly increase the
likelihood of loss-of-control.
8Do not ride faster than the conditions permit for safe operation. Excess speed greatly
increases the likelihood of loss-of-control.
9The rider should be securely seated on the vehicle ready to ride before turning the power
switch ON.
Although this bike is designed for professional racing, it is still important to ride where others can
see you. Avoid riding in another motorist’s blind spot. Know your skills and limits. Stay within your
limits in order to avoid an accident.
NOTE:
Many motorcycle accidents are caused by rider error. A typical error made by motorcycle riders is
veering wide on a turn due to EXCESSIVE SPEED or under cornering due to insucient lean angle for the
given speed.
WARNING!
Maintain a proper posture while riding. The posture of rider is important for proper control of the
motorcycle. The rider should keep both hands on the handlebars and both feet on the footrests
during operation in order to maintain control of the motorcycle. Never ride under the inuence
of alcohol or other drugs. Go to page 23 to nd detailed instructions concerning proper riding
technique.
ONE RIDER ONLY
Your bike was engineered to carry one rider and no (0) passengers. Carrying a passenger would
overload the motorcycle and alter the handling. Do not allow this to happen.
DO NOT OVERLOAD THE BIKE
Exceeding the weight limitations will adversely aect the handling of the motorcycle, and poten-
tially cause damage.
OBEY ALL LAWS
Obey all laws. KUBERG bikes are for OFF-ROAD USE ONLY. KUBERG bikes cannot be used on
public roads or sidewalks. The purchaser, owner, and/or riders of this motorcycle are directly
responsible for ensuring that they obey all local, state, and federal laws regarding the riding and
use of this motorcycle.

OWNER’S MANUAL 2017
BEFORE FIRST RIDE
NOTE:
If you purchased your KUBERG motorcycle at a local dealer your motorcycle may be fully adjusted
and ready to ride. If you purchased your KUBERG still in the original packing, please carefully follow
the instructions below and any supplemental instructions in order to complete the assembly and
adjustment of your KUBERG motorcycle.
Video instructions are available on our website at: www.kuberg.com/video-manuals
UNPACKING AND ASSEMBLY
WARNING:
Failure to properly assemble and adjust your bike prior to use may result in an accident, resulting
in damage to property, serious injury and/or death. If you are uncertain about any aspect of the
assembly and adjustment of your bike, seek help from a qualied mechanic or KUBERG Customer
Service.
1Remove your KUBERG X-Force Pro 50 from the box.
2Place the motorcycle on a solid and level surface.
3Remove all the packing materials.
4Using the supplied Allen wrench (Allen Key), make sure the steering stem is in the
forward-facing position and tighten the top and side bolts securely and evenly. Secure the
handlebars tightly in the steering stem. Double check tightness and alignment.
5Adjust the brake lever positions to suit the rider.
FIRST SETUP
1 Check the tire pressure of both tires and conrm that they are properly inated. The
optimal tire pressure for the KUBERG X-Force Pro 50 is 35 – 50 PSI (2.4 – 3.4 bar) for general
use and should never exceed 50 PSI (3.4 bar).
2Unpack the charger from its box and charge the batteries, being sure to follow the correct
charging procedure. Go to page 20 to nd detailed charging instructions.
3The X-Force Pro 50 contains both a hand brake lever and foot brake. The hand brake lever
should not compress completely to the handlebar. Each individual brake should hold
the bike securely when you push the motorcycle against the brake. If your brake needs
adjustment, follow the instructions on page 23. For novice riders, adjust the front brake so
it will not lock the front wheel easily. All riders should be aware which lever operates which
brake.
4Check the chain for tightness and lubrication.
5Set the power and torque settings to an adequate level for the rider’s experience and riding
skills. Go to page 16 to nd detailed instructions concerning how to set speed limits and
dierent riding modes.

13
WARNING!
There are no user serviceable elements incorporated into the motor, motor controller, batteries,
battery charger, throttle, or wiring harness of your KUBERG electric bike. DO NOT ATTEMPT TO
DISASSEMBLE OR ADJUST ANY OF THESE COMPONENTS. Doing so may cause extensive damage
to these components, will void your warranty, and may result in danger to persons and/or
property. If you cannot resolve any problem using this owner’s manual, contact your KUBERG
authorized dealer, or call the KUBERG Customer Service for assistance.
BREAK-IN PERIOD
To assure future reliability and top-notch performance of your KUBERG X-Force Pro 50, please,
pay extra attention during your rst 50 km/30 miles (three full-charge cycles).
Avoid full-throttle starts and accelerate gradually.
Avoid hard braking. New brakes need some time to break in with moderate use for the rst
50 km/30 miles or three full charges.
Chain tension might need adjusting after the break-in period.
MOTORCYCLE CONTROLS
MAGNETIC KILL SWITCH
The magnetic kill switch is located on the left-hand side of the handlebars. Always put the lanyard
on the left wrist of the rider and fasten it properly before each ride. Make sure that the rider has
this lanyard on his/her wrist whenever he/she is on his bike. Make sure that the rider always
wears a certied helmet and goggles. Always switch the bike into the OFF position when stopped
or parked.
The KUBERG X-Force Pro 50 also includes a Safety Kill Switch located underneath the seat panel.
If during a race, or at any other time that the bike needs to be turned o instantly, simply pull on
the red string. This will disengage the secondary magnetic kill switch.
NOTE:
To reset the Safety Kill Switch, you will need to remove the seat and re-attach the magnet.
WARNING!
If the power is turned on and the throttle is open, the bike will accelerate immediately. This is
potentially very dangerous. The rider’s right hand should be used to switch the power on, with no
hands on the throttle.

14
OWNER’S MANUAL 2017
SPEED & TORQUE CONTROL BUTTON
The speed & torque control button allows a responsible adult to set bike’s maximum power
and torque. There are three distinct power & torque modes. Go to page 16 to read detailed
instructions concerning how to set the various power & torque modes. Do not attempt to guess
these settings. Always check them before allowing the rider back on the bike.
CHARGER PORT
When it’s time to recharge the bike, the battery charger connector attaches to this port. Before
attaching, ensure that the power is switched to the OFF position. Please refer to the battery and
charging section (page 20) of this manual for more information.
WARNING!
The power on the motorcycle must be switched OFF before attaching and plugging in the charger.

15
CHARGE INDICATOR
The LED battery charge indicator is located on a plastic cover between the seat and the handle-
bars.
The LED illuminates green when the bike is fully charged, yellow when the charge reaches 65%
and red when the battery charge reaches 30%. The red light will start blinking when the battery
charge is very low. From this point, the bike will start losing power and will be able to travel
roughly 2-3 km (1-2 miles) before the motorcycle shuts down completely.
SETTING UP YOUR KUBERG
X-FORCE PRO 50 FOR RIDING
There are several ways to set up your KUBERG motorcycle for riding. You can adjust
the settings for:
1Maximum power and torque
2Top speed limit
3Braking power
WARNING!
Improper set-up is dangerous! It is your responsibility to set the motorcycle to the ability of the
rider. Failure to do so, may result in injury or death, and damage to your motorcycle.
NOTE:
A responsible adult must ensure that the KUBERG X-Force Pro 50 and its rider are prepared for every
ride. The motorcycle must be set to the abilities of the rider, and the rider and the bike must ALWAYS be
supervised. Novice riders can lose concentration quickly, and be easily distracted. If the speed is set too
high or the brakes too severe an accident could occur. RIDE SAFE!

16
OWNER’S MANUAL 2017
SETTING POWER & TORQUE MODES
Follow these steps to limit the maximum power and torque on your KUBERG X-Force Pro 50:
1With the bike OFF, press and hold the control button.
2Continue to hold the button and turn the bike ON (using the magnetic switch) wait a short
time (whilst still holding the button) and the bike will beep one, two or three times to
indicate the desired power mode. One beep indicates Beginner Mode (low-power), two
beeps indicate Intermediate Mode and three beeps indicate Race Mode (maximum-power).
Let go of the control button after the number of beeps corresponding to your desired
power mode. For example, if you want the Intermediate Mode, hold the control button
for two beeps and release. On the X-Force Pro 50, the control button is located on the top
plastic cover between the seat and the steering column.
CAUTION!
Sport and Race modes should only be used by experienced riders!
SETTING UP THE BRAKES
The brakes on KUBERG motorcycles are adjustable. Novice riders should have the front brake
‘backed o’ somewhat so it does not bite too suddenly. As the rider gets better, the brake can be
tightened up for a quicker reaction and a stronger braking force.
DRIVE TRAIN
Your KUBERG motorcycle features a traditional chain and sprockets. It is direct drive with no
gears. The chain should not need to be adjusted on a regular basis, especially when the bike is
new. However, it is important to check the chain before every ride and adjust it when necessary.
There should be very little slack in the chain.
ADJUSTING CHAIN TENSION
Follow these steps to adjust the chain tension:
1Ensure the power is turned OFF.

17
2Remove the chain tensioner by removing the mount bolt.
3Loosen the axle nuts and band brake mount bolt.
4Turn the adjustment nuts evenly on both sides. Very small movements make a big
dierence. Do not tighten so much that there is no slack at all. It should be ‘taught’ not
‘tight’.
5 While the chain guard is o, lubricate the chain and check the sprocket bolts for tightness.
6Repeat the above procedure, ensuring all bolts are tight.
7Check the wheel for alignment, and the chain for tension.
WARNING: ALWAYS RIDE WITH CHAIN COVER
The chain cover helps to prevent accidental injuries from the chain. Never ride your motorcycle
when the chain cover is not in place. Operating your motorcycle without the chain cover may
result in serious injury.
WARNING!
Failure to maintain and adjust the chain and align the wheel correctly could result in the chain
jumping o the sprockets, causing a potentially dangerous and damaging situation.
MOTOR PERFORMANCE
The KUBERG X-Force Pro 50 has multiple sensors and control software to prevent the batteries,
motor and the controller from overheating. Once the temperature of batteries, motor or
controller reaches a high temperature, the bike’s power will be limited to 70% until the
components are able to cool down. If the bike continues to overheat, the controller will shut o
the bike until the components have cooled. This takes approximately 15 to 30 minutes.
Thermal shutdown of the motor can occur when riding in situations that stress the motor for long
periods of time, such as long up-hills or continuous full throttle operation with no rest period for
the motor.
WEATHER EFFECTS ON PERFORMANCE
Very cold weather is hard on the motorcycle’s batteries and, as a result, the battery charge will not
last as long as in warm weather. This is normal and does not require maintenance or servicing.

18
OWNER’S MANUAL 2017
MAINTENANCE
KUBERG motorcycles generally require signicantly less maintenance compared to traditional
gas bikes due to their having very few moving parts, no engine, and no exhaust. Our authorized
dealers have extensive experience and know KUBERG bikes inside and out, so they can provide
high-quality service for your motorcycle. However, service at a dealer is not required to maintain
your warranty.
WARNING: PROPER MAINTENANCE OF THIS VEHICLE IS REQUIRED
Failure to maintain this vehicle in proper operating condition may lead to an accident resulting in
serious injury or death, and/or damage to property. If you have any questions about the proper
care and maintenance of this vehicle, consult your selling dealer/distributor or contact KUBERG
Customer Service ([email protected], [phone]).
BEFORE EACH RIDE
Before each ride, make sure that all bolts and nuts are fastened securely and that the tires are
properly inated. Before each ride, check that the throttle and brake controls are operating freely.
Adjust and lubricate the drive chain as necessary. This vehicle should be returned for periodic
maintenance to your selling dealer AT LEAST once per year, but more frequently if used under
severe or heavy use conditions.
DAILY MAINTENANCE AND CLEANING
Keep your KUBERG X-Force Pro 50 clean and dry. Regularly check all components for tightness
and adjustment, including handlebars, levers, axles, chain, and brakes. Check the settings for
torque and maximum speed. Check the tires for damage and for proper ination.
CLEANING
Cleaning and maintaining your KUBERG correctly will provide a more enjoyable ownership
and riding experience. By hand cleaning the bike, you can simultaneously inspect all of the
components. When cleaning the motorcycle, make sure that the charger port is closed before
washing. You are free to wash your X-Force Pro 50 with a water hose or a power wash. Even
though the bike’s components are waterproof, be careful when washing the bike around the
electrical components, especially the controller.
WARNING!
Do not operate your KUBERG if any damage is apparent. Immediately contact your local retailer/
distributor or KUBERG Customer Service.
WARNING!
There are no user serviceable elements incorporated into the motor, motor controller, batteries,
battery charger, throttle, or wiring harness of your KUBERG electric bike. DO NOT ATTEMPT TO

FRONT AND REAR BRAKES
The KUBERG X-Force Pro 50 uses the MiniCross brake system designed for racing use. Its smaller
size and use of light weight alloys combine to provide strong stopping power.
For technical specications and video tutorials you can visit the MiniCross product site at:
www.rideformula.com/products/moto-brakes/minicross/
WARNING: KUBERG BRAKES ARE ADJUSTABLE
Novice riders should have the front brake ‘backed o’ somewhat so it does not bite too suddenly.
As the rider gets better, the brake can be tightened up for a quicker and stronger response from
the brake lever.

20
OWNER’S MANUAL 2017
BRAKE SQUEAL
Dirt and humidity can cause noisy or squealing brakes. These are usually 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.
FRONT & REAR SUSPENSION
Our front and rear suspension is made by DNM. The DNM UDS-8S front end suspension and the
DNM Burner RCP-3 rear shock are highly adjustable to provide a comfortable riding experience.
Use the air valve to add or remove air depending on the weight of the rider. You can also adjust
the compression and rebound by turning the adjustment dials.
