When installing oil seals, apply a light coating
of lightweight lithium base grease to the seal
lips. Oil bearings liberally when installing, if
appropriate.

NOTE:
• The annual checks must be performed every year, except if a kilometer-based maintenance is per-
formed instead.
• From 50,000 km, repeat the maintenance intervals starting from 10,000 km.
• The air filter needs more frequent service if you are riding in unusually wet or dusty areas.
• Hydraulic brake system:
• Check the brake fluid level regularly and fill as required.
• Replace the oil seals on the inner parts of the master cylinder and caliper cylinder every two years.
• Replace the brake hoses every four years or if cracked or damaged.

REAR SHOCK ABSORBER ADJUSTMENT

REAR SHOCK ABSORBER ADJUSTMENT
WARNING
This shock absorber contains highly pressur-
ized nitrogen gas. For proper handling, read
and understand the following information
before handling the shock absorber. The man-
ufacturer cannot be held responsible for prop-
erty damage or personal injury that may result
from improper handling.
•Do not tamper with or attempt to open the
gas cylinder.
•Do not subject the shock absorber to an
open flame or other high heat sources,
otherwise it may explode due to excessive
gas pressure.
•Do not deform or damage the gas cylinder
in any way, as this will result in poor damp-
ing performance.
This shock absorber assembly is equipped with a
spring preload adjusting nut.
Never attempt to turn an adjusting mecha-
nism beyond the maximum or minimum set-
tings.
Adjust the spring preload as follows.
1. Loosen the locknut.
2. To increase the spring preload and thereby
harden the suspension, turn the adjusting nut
in direction a. To decrease the spring preload
and thereby soften the suspension, turn the
adjusting nut in direction b.
CAUTION:

REAR SHOCK ABSORBER ADJUSTMENT
3-39
NOTE:
•Use the special wrench included in the
owner's tool kit to make the adjustment.
•The spring preload setting is determined by
measuring distance A, shown in the illustra-
tion. The longer distance A is, the lower the
spring preload; the shorter distance A is, the
higher the spring preload. With each com-
plete turn of the adjusting nut, distance A
changes by 1.5 mm.
Spring preload:
Minimum (soft):
Distance A = 217 mm
Standard:
Distance A = 211 mm
Maximum (hard):
Distance A = 205 mm
2. Tighten the locknut to the specified torque.
Always tighten the locknut against the adjust-
ing nut, and then tighten the locknut to the
specified torque.
CAUTION:Locknut:
45 Nm (4.5 m·kgf)
