There is never a more important period
in the life of your motorcycle than the
period between zero and 1,600 km. For
this reason we ask that you carefully
read the following material. Because
the engine is brand new, you must not
put an excessive load on it for the first
1,600 km. The various parts in the en-
gine wear and polish themselves to the
correct operating clearances. During
this period, prolonged full throttle oper-
ation, or any condition which might re-
sult in excessive heating of the engine,
must be avoided.
EAU013290 ~ 1,000 km
Avoid operation above 5,500 r/min.
1,000 ~ 1,600 km
Avoid cruising speeds in excess of
7,000 r/min.
EC000052
CAUTION:
After 1,000 km of operation, be sure
to replace the engine oil and oil fil-
ter.
1,600 km and beyond
Proceed with normal riding.

cur during the break-in period,

diately.
