This section presents some of the most important information and recommendations to help you ride your motorcycle safely.
Please take a few moments to read these pages. This section also includes a special message for parents and location information for the safety labels on your
motorcycle. Your motorcycle can provide many years of service and pleasure—if you take responsibility for your own safety and understand the challenges you can
meet while riding.
This motorcycle has been designed for younger riders. However, not all younger riders are physically or emotionally ready to ride. Therefore before any parents allow
any youngster to ride this motorcycle, we urge them to read the Important Message to Parents beginning and the Parents, Youngsters and O-Road Motorcycles booklet.
There is much you can do to protect yourself when you ride. You’ll nd many helpful recommendations throughout this manual. The following are a few that we
consider most important.
Ride O-Road Only. Your motorcycle is designed and manufactured for o-road use only. The tires are not made for pavement, and the motorcycle does not have turn
signals and other features required for use on public roads. If you need to cross a paved or public road, get o and walk your motorcycle across.
TAKE TIME TO LEARN AND PRACTICE
Developing o-road riding skills is a gradual, step-by-step process. Start by practicing at low speeds in a safe area and slowly build your skills. Personal instruction
from an experienced rider can also be valuable.
ALWAYS WEAR A HELMET
It's a proven fact: helmets signicantly reduce the number and severity of head injuries. It is required to wear an Australian Motorcycle Standard Helmet when
riding a motor bike. So always wear an approved motorcycle helmet. We also recommend that you wear eye protection, sturdy boots, gloves, and other protective gear.
NEVER CARRY A PASSENGER
Your motorcycle is designed for one person only. There are no handholds, footrests, or seat for a second person—so never carry a passenger. A passenger could
interfere with your ability to move around to maintain your balance and control of the motorcycle.
BE ALERT FOR HAZARDS
The terrain can present a variety of challenges when you ride o-road. Continually "read" the terrain, for unexpected turns, drop-os, rocks, ruts, and other hazards.
Always keep your speed low enough to allow time to see and react to hazards.
RIDE WITHIN YOUR LIMITS
Pushing limits is another major cause of motorcycle accidents. Never ride beyond your personal abilities or faster than conditions warrant. Remember that alcohol,
drugs, fatigue, and inattention can signicantly reduce your ability to make good judgments and ride safety.
IMPORTANT SAFETY INFORMATION
DON’T DRINK AND RIDE
Alcohol and riding don't mix. Even one drink can reduce your ability to respond to changing conditions, and your reaction time gets worse with every additional drink.
So don't drink and ride, and don't let your friends drink and ride either.
KEEP YOUR DIRT BIKE IN A SAFE CONDITION
It's important to keep your motorcycle properly maintained and in safe riding condition.
Having a breakdown can be dicult, especially if you are stranded o-road far from your base. To help avoid problems, inspect your motorcycle before every ride and
perform all recommended maintenance.
That's why we urge you to read this message before you let any young person ride this motorcycle. O-road riding can be fun. But, as with riding a bicycle, bad judgment
can result in injury, and we don't want that to happen! As a parent, you can help prevent accidents by making good decisions about if, when, and how your youngster
rides this motorcycle.
RIDING READINESS
The rst decision you'll need to make is whether your youngster is ready to ride. Riding readiness varies widely from one person to another, and age and size are not
the only factors. For example, riders must be big enough to hold the motorcycle up, get on, and comfortably sit on the seat with both feet touching the ground.
They should also be able to easily reach and work the brakes, throttle, and all other controls. ATHLETIC ABILITY is necessary for riding a motorcycle. Generally speaking,
your youngster should be good at riding a bicycle before getting on a motorcycle. Can your youngster judge speeds and distances while riding a bicycle and react with
proper hand and foot actions? Anyone who does not have good coordination, balance, and agility is not ready to ride this motorcycle.
To help your youngster build condence as they're learning to ride, this bike was delivered with a speed restrictor that limits top speed. We recommend that all beginning
riders start o with the speed restrictor may be adjusted to gradually increase maximum speed as the beginner becomes more familiar with riding their bike/motorcycle.
INSTRUCTION AND SUPERVISION
If you decide that your youngster is ready to safely operate this motorcycle, make sure both of you carefully read and understand the owner's manual before riding.
Also be sure that your youngster has a helmet and other appropriate riding equipment and always wears it when operating the vehicle or sitting it.
SUPERVISION is another important obligation of parents. Even after youngsters have become skilled o-road riders, they should always ride with adult supervision.
It helps to regularly remind young riders of basic safety rules and precautions. And remember, it's your responsibility to see that the motorcycle is properly maintained
and kept in safe operating condition
SAFE AND RESPONSIBLE RIDING must be an on-going commitment—by you and your youngster. When you both put safety rst, you can enjoy more peace of mind, and
your youngster can enjoy more hours of safe o¬ road riding.
For your convenience, this DIRT BIKE comes with an ignition switch and key. Remove the key when the motorcycle is parked to help prevent unauthorized use.
Your Dirt Bike was designed as a rider-only motorcycle. It was not designed to carry a passenger or cargo. A passenger or cargo could interfere with your ability to move
around to maintain your balance and control of the motorcycle.
In addition, exceeding the weight limits or carrying an unbalanced load can seriously aect your motorcycle's handling, braking, and stability. Adding accessories or
making modications that change this motorcycle's design and performance can also make it unsafe. Also, the weight of any accessories will reduce the maximum load
the motorcycle can carry.
LOAD LIMITS
Following are the load limits for your motorcycle:
Maximum weight capacity = 50 KG’s
Includes the weight of the rider and any accessories.
CHECK ALL LOOSE PARTS - Check and secure all nuts and bolts BEFORE EVERY RIDE. Make sure the handle bars and their clamp are tight to unsure no movement

engine mechanic or hobby shop technician.
BRAKE CHECK - Check the brakes for correct functioning. When you apply pressure to the hand brake you should have a positive braking action. If not adjust the brake
accordingly. When you apply the brake with the accelerator on the brake cut-o switch will stop the motor.
FRAME, FORK AND HANDLEBARS - Check for cracks in the frame or broken connections. A broken frame is very rare but in some cases when aggressive riders run into
a gutter can break a frame. Make sure the check is done regularly.

MAINTENANCE SAFETY
The maintenance section includes instructions on how to perform some important maintenance tasks. Some of the most important safety precautions
follow. However, we cannot warn you of every conceivable hazard that can arise in performing maintenance. Only you can decide whether or not you
should perform a given task.
Read the instructions, before you begin, and make sure you have the tools and skills required.
To help prevent the motorcycle from falling over, park it on a rm, level surface, using the side stand or a maintenance stand to provide support.
To reduce the possibility of a re or explosion, be careful when working around gasoline. Use only a non-ammable (high ash point) solvent such as
kerosene—not gasoline— to clean parts. Keep cigarettes, sparks, and ames away from all fuel- related parts.
IMPORTANT SAFETY PRECAUTIONS
Make sure the engine is o before you begin any maintenance or repairs.
This will help eliminate several potential hazards:
- Carbon monoxide poisoning from engine exhaust. Be sure there is adequate ventilation whenever you operate the engine.
- Burns from hot motorcycle parts. Let the engine and exhaust system cool before touching
- Injury from moving parts. Do not run the engine unless instructed to do so.
