FRONT FORK
EC556010
HANDLING NOTE
NOTE:
• With the 97 or later models, the dampar rod
diameter is 12.5 mm (0.49 in). If the dimen-
sion a of your dampar rod holders is 12 mm
(0.47 in), drill it to expand its diameter to 14
mm (0.55 in).
• The front fork requires careful attention. So it
is recommended that the front fork be main-
tained at the dealers.
C C CAUTION:
To prevent an accidental explosion of air,
the following instructions should be
observed:
• The front fork with a built-in piston rod has
a very sophisticated internal construction
and is particularly sensitive to foreign
material.
Use enough care not to allow any foreign
material to come in when the oil is
replaced or when the front fork is disas-
sembled and reassembled.
• Before removing the cap bolts or front
forks, be sure to extract the air from the air
chamber completely.
