WARNING:

This operator’s manual contains important safety and 

maintenance information. Read it carefully and make sure 

you understand all included information before riding. 

Failing to follow the warnings contained in this manual 

could result in SERIOUS INJURY or DEATH.

NOTICE TO PARENTS

This dirt bike is built for use by persons age 16 and older. 

Never allow anyone under the age of 16 to operate the dirt 

bike. 
Children differ in skills, physical abilities, and judgement. 

Some children may not be able to operate a dirt bike safely. 

Parents should supervise their child’s use of the dirt bike at 

all times. Parents should permit continued use only if they 

determine that the child has the ability to operate the dirt 

bike safely.

It is very important that every person who rides the dirt bike 

complete a training course.

READ ALL INSTRUCTIONS

It is important that this manual remain with the vehicle when 

you transfer or loan it to another user or owner.

All information, illustrations, photographs and specifications 

contained in this manual are based on the latest product 

information available at the time of publication. Due to im-

provements or other changes, there may be some discrep-

ancies in this manual. We reserve the right to make product 

changes at any time, without notice and without incurring 

any obligation to make the same or similar changes to the 

vehicle previously built or sold.

  Carefully read and understand this manual and all labels 

and follow the operating procedures described.

  Never operate a dirt bike without proper instruction. Take 

a training course. Beginners should receive training from a 

certified instructor. Contact an authorized dirt bike dealer 

or call Motorcycle Safety Foundation at 1-800-446-9227 

to find out about the training courses nearest you.

  Never carry a passenger or cargo on a dirt bike.

  Do  not  operate  the  engine  in  a  confined  space  where 

dangerous carbon monoxide fumes can collect. Carbon 

monoxide, a colorless, odorless, and extremely dangerous 

gas, can cause unconsciousness or death.

  Never consume drugs or alcohol before or while operating 

this dirt bike.

  Never operate a dirt bike on any paved surfaces, including 

sidewalks, driveways, parking lots, and streets.

  Never operate a dirt bike on any public street, road, or 

highway, even a dirt or gravel one.

  Never operate the dirt bike at night. Night is defined as 

the period of time 30 minutes before sunset to 30 minutes 

after sunrise.

  Never operate a dirt bike without wearing a DOT or Snell-

approved motorcycle helmet that fits properly. You should 

also wear eye protection with side shields (goggles) marked 

to comply with ANSI Z87.1, gloves, over the ankle boots, 

long-sleeved shirt or jacket, and long pants.

  Never operate this dirt bike at excessive speeds. Always 

ride  at  a  speed  that  is  proper  for  the  terrain,  visibility, 

operating conditions, and your experience.

  Always keep both hands on the handlebars and both feet 

on the foot rests of the dirt bike during operation.

  Always be careful when skidding or sliding. Learn to safely 

control skidding or sliding by practicing at low speeds and 

on level, smooth terrain. On extremely slippery surfaces 

such as ice, go slowly and be very cautious in order to 

reduce the chance of skidding or sliding out of control.

  Never operate the dirt bike on hills too steep for the dirt 

bike or for your abilities. Practice on smaller hills before 

attempting larger hills.

  Check the terrain carefully before you start up any hill. 

Never climb hills with excessively slippery or loose sur-

faces. Shift your weight forward. Never open the throttle 

suddenly. Never go over the top of any hill at high speed.

  Never attempt wheelies, jumps, or other stunts.

  Never operate a dirt bike in water.

  Always inspect your dirt bike each time you use it to make 

sure it is in safe operating condition. Always follow the 

inspection and maintenance procedures and schedules 

described in this manual.

  Never modify a dirt bike through improper installation or 

use of accessories.

  Always use the size and type tires specified in this manual. 

Always maintain proper tire pressure as described in this 

manual.

  Check the terrain carefully before you start down any hill. 

Shift your weight backward. Never go down a hill at high 

speed. 

  Never exceed the stated load capacity of 130 lbs. (59 kg).

  Never ride alone. This dirt bike can go 34 miles (55 km) 

in an hour, which may be farther than you can walk back 

in the event of a problem with the dirt bike.

  We believe in conservation and protection of the earth’s 

natural  resources.  We  encourage  every  vehicle  owner 

and operator to do the same by obeying posted signs and 

riding only in areas designated and approved for off-road 

recreational use.
