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.

Your Yamaha engine has been
designed to use regular unleaded
gasoline with a research octane num-
ber of 91 or higher. If knocking (or
pinging) occurs, use a gasoline of a
different brand or premium unleaded
fuel. Use of unleaded fuel will extend
spark plug life and reduce mainte-
nance costs.

Catalytic converter(for Switzerland and Austria)
This motorcycle is equipped with a
catalytic converter in the exhaust
chamber.
EW000128
