IMPORTANT
BREAK-IN INFORMATION FOR
YOUR MOTORCYCLE
The first 1000km(600miles) are the most impor-
tant in the life of your motorcycle .
Proper break-in operation during this time will
help ensure maximum life and performance
from your new motorcycle.
Hyosung 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.
