Even with the transmission in
the neutral position, do not
coast for long periods of time
with the engine off, and do not
tow the motorcycle for long
distances. The transmission is
properly lubricated only when
the engine is running. Inade-
quate lubrication may damage
the transmission.
Always use the clutch while
changing gears to avoid dama-
ging the engine, transmission,
and drive train, which are not
designed to withstand the
shock of forced shifting.

Tips for reducing fuel
consumption
Fuel consumption depends largely on
your riding style. Consider the follo-
wing tips to reduce fuel consumption:
Shift up swiftly, and avoid high
engine speeds during accelera-
tion.
Do not rev the engine while shif-
ting down, and avoid high engine
speeds with no load on the engi-
ne.
Turn 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 cros-
sings).
EAU16841
Engine break-in
There is never a more important
period in the life of your engine than
the period between 0 and 1600 km
(1000 mi). For this reason, you should
read the following material carefully.
Since the engine is brand new, do not
put an excessive load on it for the first
1600 km (1000 mi). The various parts
in the engine wear and polish them-
selves to the correct operating clea-
rances. During this period, prolonged
full-throttle operation or any condition
that might result in engine overhea-
ting must be avoided.
EAU17101
0–1000 km (0–600 mi)
Avoid prolonged operation above
4500 r/min. NOTICE: After 1000
km (600 mi) of operation, the
engine oil must be changed,
and the oil filter element repla-
ced.
