INTRODUCTION
EBU17203
Congratulations on your purchase of the Yamaha YFZ05YYXJ. This ATV represents the result of many
years of Yamaha experience in the production of fine sporting, touring, and pacesetting racing machines.
With the purchase of this Yamaha, you can now appreciate the high degree of craftsmanship and reliability
that have made Yamaha a leader in these fields.
This manual will provide you with a good basic understanding of the features and operation of this ATV.
This manual includes important safety information. It provides information about special techni-
ques and skills necessary to ride the ATV. It also includes basic maintenance and inspection proce-
dures. If you have any questions regarding the operation or maintenance of your ATV, please consult a
Yamaha dealer.
AN IMPORTANT SAFETY MESSAGE:
Read this manual completely before operating your ATV. Make sure you understand all instructions.
Pay close attention to the warning and notice labels on the ATV.
This ATV should not be operated by a child under 6 years of age.
AN IMPORTANT NOTE TO PARENTS:
This ATV is not a toy. Before you let your child ride this ATV, you should understand the instructions and
warnings in this Owner’s Manual. Then be sure your child understands and will follow them. Children differ
in skills, physical abilities and judgment. Some children may not be able to operate an ATV safely. Parents
should supervise their child’s use of the ATV at all times. Parents should permit continued use only if they
determine that the child has the ability to operate the ATV safely.
UBW461E0.book Page 1 Tuesday, January 31, 2017 5:13 PM

Your ATV was delivered with an adjustable speed limiter. Yamaha recommends that all beginners start off
to limit the amount of speed available while they learn. The adjusting screw may be gradually turned out
as the beginner becomes more familiar with operating the ATV. Parents should decide when to adjust the
ATV for more power as their youngster’s riding skills improve. Once the ATV rider can operate with skill at
the top speed permitted by adjusting the vehicle speed limiter alone, the engine speed limiter plate can be
removed. Since removal of this limiter will result in a significant increase in power, turn the vehicle speed
limiter adjusting screw completely back in again; adjust it out in stages as done previously.
If your child is a beginner or is inexperienced, he or she should take a training course.
