Introduction
safely. Parents should supervise their child's use of the motorcycle at all times.
Parents should permit continued use only if they determine that the child has the
ability to operate the motorcycle safely.
Your motorcycle is equipped with an adjustable speed limiter and a 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.
Motorcycles are single track vehicles. Their safe use and operation are de-
pendent upon the use of proper riding techniques as well as the expertise of
the operator. Every operator should know the following requirements before
riding this motorcycle.
He or she should:
 Obtain thorough instructions from a competent source on all aspects of mo-
torcycle operation.
 Observe the warnings and maintenance requirements in this Owner's Manu-
al.
 Obtain qualified training in safe and proper riding techniques.
 Obtain professional technical service as indicated in this Owner's Manual
and/or when made necessary by mechanical conditions.
