Slow compression damping
Minimum (soft)
20 click(s) in direction "b"*
Standard
9 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.
• Loose bead stoppers allow the tire to slip off its
position on the rim when the tire pressure is
low.
• If the tire valve stem is found tilted, the tire is
considered to be slipping off its position. Cor-
rect the tire position.
