Speedometer unit The speedometer unit is equipped
with a speedometer, an odometer
and a tripmeter. The speedometer
shows riding speed. The odometer
shows the total distance traveled.
The tripmeter shows the distance
traveled since it was last set to zero
with the reset knob. The tripmeter
can be used to estimate the distance
that can be traveled with a full tank of
fuel. This information will enable you
to plan future fuel stops.
NOTE:
Only for the German model equipped
with a speed limiter:
The speed limiter prevents the motor-
cycle from exceeding a riding speed
of 80 km/h.

PRE-OPERATION CHECKS

NOTE:
Pre-operation checks should be made each time the motorcycle is used. Such an inspection can be accomplished in a
very short time; and the added safety it assures is more than worth the time involved.
EWA00033
wIf any item in the Pre-operation check list is not working properly, have it inspected and repaired before operat-
ing the motorcycle.Chassis fasteners•Make sure that all nuts, bolts and screws are properly tightened.
•Tighten if necessary.—
Instruments, lights, signals
and switches•Check operation.
•Correct if necessary.3-1–3-3, 6-34–6-37

OPERATION AND IMPORTANT RIDING POINTS

EAU00424
Tips for reducing fuel
consumptionFuel consumption depends largely on
your riding style. Consider the follow-
ing tips to reduce fuel consumption:
8Thoroughly warm up the engine.
8Turn the starter (choke) off as
soon as possible.
8Shift up swiftly, and avoid high
engine speeds during accelera-
tion.
8Do not rev the engine while shift-
ing down, and avoid high engine
speeds with no load on the
engine.
8Turn the engine off instead of let-
ting it idle for an extended length
of time (e.g., in traffic jams, at
traffic lights or at railroad cross-
ings).
EAU00436
Engine break-inThere is never a more important peri-
od in the life of your engine than the
period between 0 and 1,000 km. For
this reason, you should read the fol-
lowing material carefully.
Since the engine is brand new, do
not put an excessive load on it for the
first 1,000 km. The various parts in
the engine wear and polish them-
selves to the correct operating clear-
ances. During this period, prolonged
full-throttle operation or any condition
that might result in engine overheat-
ing must be avoided.
EAU04390
0–500 km
Avoid prolonged operation above 1/3
throttle.
500–1,000 km
Avoid prolonged operation above 1/2
throttle.
ECA00118
cCAfter 1,000 km of operation, the
engine oil must be changed, and
the oil filter element and the oil
strainer cleaned.1,000 km and beyond
The vehicle can now be operated
normally.
EC000049
cCIf any engine trouble should occur
during the engine break-in period,
immediately have a Yamaha dealer
check the vehicle.
