The first 1,000km(600miles) are the most
important in the life of your motorcycle .
Proper break-in operation during this time will
help ensure maximum life and performance
from your new motorcycle.
 parts are manufactured of high quality
materials, and manufactured parts are finished
to close tolerances. Proper break-in operation
allows the machined surfaces to polish each
other and mate smoothly.
Motorcycle reliability and performance depend
on special care and restraint exercised during
the break-in period. It is especially important
that you avoid operating the engine in a man-
ner which could expose the engine parts to
excessive heat.
Please refer to the BREAK-IN section for spe-
cific break-in recommendations.
NOTE: This provides special information to
make maintenance easier or important instruc-
tions clearer.
