Slow compression damping
Minimum (soft)
20 click(s) in direction "b"*
Standard
13 click(s) in direction "b"*
Maximum (hard)
0 click(s) in direction "b"*
* With the adjusting screw fully turned in di-
rection "a"
TIP
Although the total number of clicks of a damping
force adjusting mechanism may not exactly
match the above specifications due to small dif-
ferences in production, the actual number of
clicks always represents the entire adjusting
range. To obtain a precise adjustment, it would
be advisable to check the number of clicks of
each damping force adjusting mechanism and
to modify the specifications as necessary.

CHECKING THE TIRES

1. Measure:
• Tire pressure
Out of specification  Regulate.
Tire air pressure (measured on
cold tires)
Front
100 kPa (1.00 kgf/cm², 15 psi)
Rear
100 kPa (1.00 kgf/cm², 15 psi)
TIP
• Check the tire while it is cold.
• Because if the bead stopper tightening nut is
loose when the tire pressure is low, the tire
could slip off the rim, thus be sure to check and
tighten the bead stopper tightening nut "a".
• If the tire valve stem "b" is found tilted, the tire
is considered to be slipping off its position. Cor-
rect the tire position.
