OWNER’S MANUAL

INTRODUCTION
EAU41070
Congratulations on your purchase of the Yamaha PW50(X). This model is the result of Yamaha’s vast experience in the pro-
duction of fine sporting, touring, and pacesetting racing machines. It represents the high degree of craftsmanship and reli-
ability that have made Yamaha a leader in these fields.
This manual will give you an understanding of the operation, inspection, and basic maintenance of this motorcycle. If you
have any questions concerning the operation or maintenance of your motorcycle, please consult a Yamaha dealer.
The design and manufacture of this Yamaha motorcycle fully comply with the emissions standards for clean air applicable
at the date of manufacture. Yamaha has met these standards without reducing the performance or economy of operation of
the motorcycle. To maintain these high standards, it is important that you and your Yamaha dealer pay close attention to the
recommended maintenance schedules and operating instructions contained within this manual.
AN IMPORTANT SAFETY MESSAGE:

READ THIS MANUAL CAREFULLY AND COMPLETELY BEFORE OPERATING THIS MOTORCYCLE. MAKE SURE
YOU UNDERSTAND ALL INSTRUCTIONS.

PAY CLOSE ATTENTION TO THE WARNING AND CAUTION 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 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.

INTRODUCTION
Your motorcycle was delivered with an adjustable speed limiter and power reduction 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 man-
ifold 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 rider 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 sig-
nificant 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 DEPENDENT UPON
THE USE OF PROPER RIDING TECHNIQUES AS WELL AS THE EXPERTISE OF THE OPERATOR. EVERY OPERA-
TOR 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 THE OWNER’S MANUAL.

OBTAIN QUALIFIED TRAINING IN SAFE AND PROPER RIDING TECHNIQUES.

OBTAIN PROFESSIONAL TECHNICAL SERVICE AS INDICATED BY THE OWNER’S MANUAL AND/OR WHEN
MADE NECESSARY BY MECHANICAL CONDITIONS.
