AN IMPORTANT SAFETY MESSAGE:
Read this manual, the “PARENTS, YOUNGSTERS AND OFF-HIGHWAY MO-
TORCYCLES” booklet, and the “TIPS AND PRACTICE GUIDE FOR THE OFF
HIGHWAY MOTORCYCLIST” booklet carefully and completely before oper-
ating this motorcycle. Make sure you understand all instructions.
Pay close attention to the warning and notice labels on the motorcycle.
Never operate a motorcycle without proper training or instruction.
Weight of the rider should not exceed 25 kg (55 lb).
AN IMPORTANT NOTE TO PARENTS:
This motorcycle is not a toy. Before you let your child ride this motorcycle, you
should understand the instructions and warnings in this Owner’s Manual. Then be
sure your child understands and will follow them. Also read the “PARENTS,
YOUNGSTERS AND OFF-HIGHWAY MOTORCYCLES” and the “TIPS AND
PRACTICE GUIDE FOR THE OFF HIGHWAY MOTORCYCLIST” booklets sup-
plied with this motorcycle when new or available from your Yamaha dealer. Chil-
dren differ in skills, physical abilities, and judgment. Some children may not be
able to operate a motorcycle safely. Parents should supervise their child’s use of
the motorcycle at all times. Parents should permit continued use only if they de-
termine that the child has the ability to operate the motorcycle safely.
Your motorcycle is equipped with an adjustable speed limiter and power reduc-
tion plate. Yamaha recommends that all beginners start off with the speed limiter
adjusting screw turned in and the power reduction plate installed in the exhaust
manifold to limit the power available while they learn. The limiter screw may be
gradually turned out to increase maximum speed as the beginner becomes more
familiar with operating the motorcycle. Parents should decide when to adjust the
motorcycle for more power as their youngster’s riding skills improve. Once the rid-
er can operate with skill at the top speed permitted by adjusting the speed limiter
alone, the power reduction plate can be removed. Since removal of this plate will
result in a significant increase in power, turn the speed limiter back in again; adjust
it out in stages as you did before.
