Motorcycles are fascinating vehicles, which can give you an unsurpassed feeling of power and freedom. However, they also impose certain limits, which you must accept; even the best motorcycle does not ignore the laws of
1
physics.
Regular care and maintenance are essential for preserving value and operating condition of your motorcycle.
Moreover, what is true for the motorcycle is also true for the rider: good performance depends on being in good
shape. Riding under the influence of medication, drugs and alcohol is, of course, out of the question. Motorcycle
riders––more than car drivers––must always be at their mental and physical best. Under the influence of even
small amounts of alcohol, there is a tendency to take dangerous risks.
Protective clothing is as essential for the motorcycle rider as seat belts are for car drivers and passengers. Always
wear a complete motorcycle suit (whether made of leather or tear-resistant synthetic materials with protectors),
sturdy boots, motorcycle gloves and a properly fitting helmet. Optimum protective wear, however, should not encourage carelessness. Although full-coverage helmets and suits, in particular, create an illusion of total safety and
protection, motorcyclists will always be vulnerable. Riders who lack critical self-control run the risk of going too fast
and are apt to take chances. This is even more dangerous in wet weather. The good motorcyclist rides safely, predictably and defensively––avoiding all dangers, including those caused by others.
Enjoy your ride!

INSTRUMENT AND CONTROL FUNCTIONS
NOTE:
Depending on the market where the
motorcycle is sold, the speedometer can
be set to either mph or km/h. When the
speedometer is set to mph, the odometer
counts in miles (1 mile = 1.61 km).
Odometer and tripmeter modes
Pushing the “SET” button switches the display between the odometer mode “ODO”
and the tripmeter modes “TRIP 1” and
“TRIP 2” in the following order: ODO 6
TRIP 1 6 TRIP 2 6 ODO
When the fuel warning light comes on, the
display will automatically change to the fuel reserve tripmeter mode “TRIP F” and
start counting the distance traveled from
that point. In that case, pushing the “SET”
button switches the display between the
various tripmeter and odometer modes in
the following order: TRIP F 6 TRIP 1 6
TRIP 2 6 ODO 6 TRIP F
To reset a tripmeter, select it by pushing
the “SET” button, and then push the “RE-
SET” button for at least one second. If you
do not reset the fuel reserve tripmeter
manually, it will reset itself automatically
and the display will return to the prior
mode after refueling and traveling several
kilometers.
Oil change indicator
At the initial 1,000 km (620 mi) and every
10,000 km (6,200 mi) thereafter, the message “OIL CHANGE” appears in the display for a few seconds when the key is
turned to “ON”, to indicate that the engine
oil should be changed.
After changing the engine oil, reset the oil
change indicator.
If the engine oil is changed before the oil
change indicator appears in the display
(i.e. before the periodic oil change interval
has been reached), the indicator must be
reset after the oil change for the next periodic oil change to be indicated at the correct time.
NOTE:
When the message “OIL CHANGE”
appears in the display, be sure to change
the engine oil as soon as possible. In addition to these kilometer-based oil changes,
be sure to have a Yamaha dealer perform
the annual checks specified in the periodic maintenance and lubrication chart on
page 6-2.
