INTRODUCTIONAN IMPORTANT NOTE TO PARENTS:
This motorcycle is not a toy. Before you let your child ride this motorcycle, you should understand the instructions and warn-
ings in this Owner’s Manual. Then be sure your child understands and will follow them. Children differ in skills, physical abil-
ities, 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 determine that the child has the ability to
operate the motorcycle safely.
Your motorcycle is equipped with a removable power reduction plate. Yamaha recommends that all beginners start off with
the power reduction plate installed to limit the engine power available while they learn. Parents should decide when to re-
move the power reduction plate from the motorcycle for more power as their youngster’s riding skills improve. Once the rider
can operate with skill at the top speed permitted by power reduction plate installed, the power reduction plate can be re-
moved.
Motorcycles are single track vehicles. Their safe use and operation are dependent 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 motorcycle operation.


Observe the warnings and maintenance requirements in this Owner’s Manual.


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.
