OPERATION

WARNING:

Always wear appropriate protective clothing and acces-

sories: a properly fitting helmet, eye protection (goggles) 

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

boots, long-sleeved shirt or jacket, chest protector, and 

long pants.

WARNING:

Always wear eye protection with side shields (goggles)

 

marked to comply with ANSI Z87.1. Failure to do so could 

result in objects being thrown into your eyes, resulting in 

possible serious injury.

WARNING:

Do not allow familiarity with product to make you care

-

less. Remember that a careless fraction of a second is 

sufficient to inflict serious injury.

SAFETY GEAR

A  DOT  or  Snell-approved  motorcycle  helmet  is  the  most 

important part of your safety gear because it can help pre

-

vent a serious head injury. Choose a helmet that fits snugly. 

Retailers can help in selecting a good quality helmet which 

fits properly.

Always wear eye protection when you ride. If a rock or 

branch hit your eyes, you could be severely injured. Wear 

shatterproof goggles.

BREAK-IN

CAUTION:

Carefully and correctly follow the break-in procedures. 

Failure to follow the break-in procedures can significantly 

shorten the life of your dirt bike by causing excessive wear 

and damaging the engine.

The first month is the most important in the life of your vehicle. 

Proper operating during this break-in period will be helpful for 

assuring maximum life and performance of your new dirt bike. 

The following guidelines explain proper break-in procedures.

Vary the engine rotating speed. 

Vary the engine rotating 

speed during the break-in period. This allows the parts to 

“load” and then “unload” (allowing the parts to cool). Although 

it is essential to place some stress on the engine components 

during break-in, you must be careful not to load the engine 

too much.

Avoid constant low or high rotating speed.

 Operating the 

engine at constant low rotating speed (light load) can cause 

parts to glaze and not seal properly. Operating the engine 

at a constant high rotating speed can cause excessive heat, 

which can damage internal components. Allow the engine 

to accelerate freely without exceeding the maximum throttle 

limit.

EYE 

PROTECTION 

(GOGGLES)

HELMET

LONG-SLEEVED 

SHIRT

LONG PANTS

GLOVES

BOOTS

Allow the engine lubricant to circulate before riding.

 Allow 

enough idling time after warm or cold engine starting. This 

allows the lubricant to reach all critical engine components.

Observe and document your initial and most critical ser-

vice. 

The initial service (break-in maintenance) is the most 

important service that your vehicle will receive. Observing a 

proper break-in operating, will help engine components seal 

properly. Maintenance required as part of the initial service 

includes proper adjustments, tightening of all bolts and nuts, 

and replacement of dirty oil. Timely performance of this ser

-

vice will help you get the best service life and performance 

of the engine.

WARNING:

Always inspect your dirt bike according to the pre-ride 

inspection checklist each time before riding and make 

sure it is in a safe operating condition. Failure to inspect 

the dirt bike before operating could increase the chance 

of an accident, resulting in serious personal injury or 

equipment damage.
