Important Safety Information

A mini bike can provide many years of service and pleasure, provided you take responsibility for
safety, properly maintain your mini bike and understand the challenges you may encounter while
riding.

This mini bike has been designed for younger riders. However, not all youngsters meet the
physical and emotional levels that are needed for riding. Before parents allow any children to ride this
mini bike, we strongly recommend that both of you read this entire manual so you are fully informed
before deciding if your children are ready to ride. Listed below are some of the most important safety
measures one should take when riding.

Never Ride Without a Helmet The following statement is a proven fact:
``Helmets signicantly reduce the number and severity of head injuries.” Never ride your mini bike
without a helmet. Even a crash at slow speed can result in a fatal head injury if you are not wearing
a helmet. Monster Moto recommends wearing helmets that have been certied for safety by helmet
testing organizations whom are independent from the helmet manufacturer. We also recommend
that you wear eye protection, boots, gloves, and other protective gear such as o-road riding pants.

Never Carry a Passenger This mini bike has been designed for ONE rider only.
There are no passenger pegs, footrests, handles or seat room for a passenger. Riding with a passenger
can interfere with your ability to operate and/or control the mini bike and may result in serious injury
or death.

Ride O-Road Only This mini bike has been designed and manufactured for
o-road use only. The mini bike is not equipped with lights, turn signals, horn and other features
required to drive a mini bike on public roads. The tires are not designed for pavement and will make
the mini bike unstable if it is ridden on pavement. If you have to cross a paved road, dismount and
walk the mini bike across the road.

Ride Within Your Limits Never attempt to ride your mini bike in a manner that is
beyond your skill level. It takes time to learn o-road riding skills. Learn to ride your mini bike step by
step. Start by practicing on safe terrain at slow speeds and gradually build your skill level. Instruction
from an experienced rider(s) is highly recommended. Alcohol, drug use, and fatigue will reduce your
ability to make good decisions and ride safely. Monster Moto does not recommend minibike usage
when inuenced by alcohol or drug use or when fatigued.

Be Alert for Hazards The terrain in which you ride can present many hazards.
Always “scan” the terrain ahead of you continually. Watch for unexpected turns, drop-os, ditches,
rocks and other hazards. Always maintain a speed slow enough to allow you enough time to see and
react to hazards.

Do Not Drink and Ride Even one drink can impair your ability to ride a
mini bike safely. Each drink afterward will make the impairment worse. Do not drink and ride. Do
not let your friend’s drink and ride. Remember, in most states throughout the United States, you can
be arrested and charged with Driving Under the Inuence (DUI) if you are riding a mini bike while
intoxicated. This applies to o-road mini bikes as well.

Important Safety Information for Parents

As a parent, your child’s safety is your rst priority. Riding an o-road mini bike is very fun.
However, just like riding a bicycle, bad decisions can result in injury. As a parent, you can prevent
accidents by making informed decisions about if, when and how your child will ride. Always
supervise your child when he/she is riding.

Before you allow your child to ride, you need to decide if he/she is capable of riding. Riding readiness
can vary tremendously from one person to another. Age and size are not the only factors that help
determine one’s riding readiness. There are three other factors that you should also consider before
deciding if your child is ready to ride.

First, consider physical ability of your child. Riders must be able to hold the mini bike up, get on,
and sit comfortably with both feet on the ground. The rider must also be able to reach all of the
controls on the handlebars and work the brakes. Second, consider your child’s athletic ability. Your
child should be good at riding a bicycle before riding a mini bike. Determine if your child can judge
speeds and distances while riding a bicycle and react with the proper hand and foot actions. Any
person who does not have good coordination, balance, and agility should not ride this mini bike.

Finally, determine your child’s level of mental and emotional maturity. It is imperative that you are
honest with yourself when you ask yourself the following questions: Does your child think through
problems and come to logical conclusions? Does your child obey your rules when they ride their
bicycle? If your child makes bad judgements, takes unwarranted risks and/or does not obey your
rules, they should not ride this mini bike.

If you have decided that your child is ready to ride, please remember the following points and never
let your child ride without a helmet. It is up to you (parent) to ensure your child’s safety, even if they
learn to ride from another experienced adult. Never push your child to try things faster than they are
willing or capable of doing. Always supervise your child when they are riding and regularly remind
them about safety rules. As a parent it is your responsibility to be sure that the mini bike is properly
maintained and kept in safe operating condition.

Modifying this mini bike or using parts not manufactured by Monster Moto can make your
mini bike unsafe. Before you consider making any modications or adding an accessory, please read
the following information carefully.

Improper accessories or modications can cause a crash in which you can be
seriously hurt or killed. Follow all instructions in this owner’s manual regarding modications and
accessories.

Monster Moto strongly recommends that you do not remove any original equipment or
modify your mini bike in any way that may alter the design and/or operation. Such a change could
drastically impair the stability, handling, acceleration, and braking capabilities of the mini bike and
cause a crash. We also strongly suggest that you do not make any modications to the exhaust
system components.

Operating Controls and Component Locations

When you ride a mini bike o-road, you need to be able to operate the throttle, brakes,
and other controls without stopping to look at them. Please read this section carefully
before you ride your mini bike. This section of the manual will describe the function,
location, and operation of all the basic controls of your mini bike.

Your Monster Moto MMB80 is shipped with

Operating Controls

Fuel Valve

Choke Lever

Engine Stop

The two way fuel valve is used to control the ow of fuel
from the gas tank to the carburetor. The valve is located
under the gas tank. Turning the fuel valve to the “ON” posi­tion before starting the engine allows fuel to ow from the
tank to the carburetor. Turning the fuel valve to the “OFF”
position after shutting o the engine stops the ow of
fuel from the gas tank to the carburetor. Always keep the
fuel valve in the “OFF” position when you are not using the
mini bike.

The choke lever is used for starting the engine when it is
cold or when you live in a cold weather climate. It is located
above the air lter on the back of the engine. The choke
lever increases the amount of fuel in the air/fuel mixture
that is delivered to the engine. See the photo to the right.
“Start” - Choke Fully ON “Run” - Choke Fully OFF

The engine stop switch is used to turn o the engine.
When the switch is in the “OFF” position it will remove the
spark from the ignition system. To start and ride the mini
bike, push the small red button (top). This is the “RUN”
position. To shut o the engine, push the large red button
(bottom). This is the “OFF” position.

Throttle

The throttle controls the speed of the engine. To increase
engine speed, twist the throttle grip toward you. To re­duce engine speed, twist the throttle grip away from you.
The throttle is spring loaded and will return to the closed
position (engine idle) when you remove your hand.

Operating Controls

Rear Brake Lever

The brake lever is used to apply the brake to the rear wheel
and will slow or stop the mini bike. When you pull back on
the lever, brake uid is forced into the brake caliper causing
the caliper to close on the brake disc. The amount of force
that you use when pulling the brake lever will determine
how much braking power is applied. To release the rear
brake, release the brake lever.

Pull Starter Cord

Air Filter

The air lter is used to keep dirt and large objects out
of the engine’s air supply. It is located at the rear of the
engine under the air lter cover. Examine the lter before
each ride to be sure it is not dirty and/or full of debris. You may
also use air lter oil (usually in spray cans) to keep the lter
owing properly.

The Pull Starter Cord is used to start the engine and has a
recoil mechanism to retract the cord after the engine has
been started. It is located on the right side of the mini-bike,
directly below the front of the seat.

Spark Plug

The spark plug is used to produce the spark that res the
engine. You should never touch the spark plug when the
engine is running or you will be shocked. Please refer to the
Basic Maintenance Procedures section of this manual for
detailed instructions on cleaning and replacing a spark
plug.

Operating Controls

Kick Stand

The kick stand is used to support the mini bike when it is
parked. To operate, use your foot to lower the stand. Always
raise the stand before riding.

Brake Mechanism

The MMB80 mini bike is equipped with a rear disc brake.
It provides power to safely bring the mini bike to a stop. It
will also hold the mini bike at a stop if the engine is running.
Refer to the Basic Maintenance Procedures section for brake
adjustment instructions.

Chain Tensioner

The Chain Tensioner is located on the frame, near the rear
wheel on the frame. It is used to maintain proper chain
tension. The adjustment screw will increase or decrease
the slack on the chain. Please see Basic Maintenance
Procedures to understand how to determine proper
chain tension and for instructions to make adjustments to
maintain proper tension.

Before Riding

Before you ride, you must be absolutely sure that you and your mini bike are ready to ride. To help
you get prepared, this section of the manual will discuss how to evaluate your riding readiness and
how to preform our recommended pre-ride inspection of your mini bike. If you are a parent, please
be sure you have read the section Important Message to Parents on page 4.

Are you Ready to Ride?

Before you ride your mini bike for the rst time, we strongly recommend the following:

1. Completely read this manual.

2. Be sure you have read and understand all of the safety messages and labels.

3. You know how to operate all of the mini bike’s controls.

Before each ride, we also strongly recommend that you:

1. Are in good physical and mental condition.

2. Are free of alcohol and other drugs.

3. Are wearing an approved mini bike helmet with a tight chin strap, eye protection and other
protective clothing.

Protective Gear & Apparel

For your safety, we strongly recommend that you always wear an approved helmet, eye protection,
boots, gloves, long pants and a long sleeved jersey , shirt or jacket whenever you ride. Although
complete protection is not possible, wearing the proper gear can reduce the chance of and severity
of injuries when you ride.

Not wearing a helmet increases the chance of serious injury or death in a crash. Be
sure you always wear your helmet and other protective apparel when you ride.

Helmets and Eye Protection - Your helmet is your most important piece of riding gear because
it oers the best protection against head injuries. A good helmet will be approved by a testing
organization independent of the helmet manufacturer and will have a chin strap that can be tight­ened securely. Open-face helmets oer some protection, but a full-face helmet oers the most
protection. When purchasing a helmet, regardless of style, look for a DOT (Department Of Transporta­tion) sticker (USA only). If the helmet has been tested by an independent organization such as the
Snell Institute, you will usually nd their logo on a tag inside the padding of the helmet

Additional Riding Gear - In addition to your helmet and eye protection, we also recommend:

1. Sturdy o-road riding boots to help protect your feet, ankles and lower legs.

2. O-Road riding gloves to protect your hands.
3 Riding pants with knee and hip pads, a riding jersey with elbow pads and a chest/shoulder
protector.
