ADJUSTING THE REAR BRAKE

ADJUSTING THE REAR BRAKE
1. Check:
•Brake pedal position
(distance afrom the top of the rider
footrest to the top of the brake pedal)
Out of specification ➔Adjust.
2. Adjust:
•Brake pedal position
•Tighten lock nut.
After adjusting the brake pedal position, make
sure the brake doesn't oppose resistance.
CAUTION:
•Loosen lock nut (1).
•Turn the adjuster (2) either way to obtain the
correct pedal height.
WARNING
If the brake brake pedal has a soft or slack
feel, this means that there is air in the brake
system. It should be bled away before using
the motorcycle. Air in the system seriously
affects the effectiveness of braking and may
cause loss of control of the motorcycle.

CHECKING THE BRAKE FLUID LEVEL
3-32
INSP
ADJ
CHECKING THE BRAKE FLUID LEVEL
1. Stand the motorcycle on a level surface.
NOTE:
•Place the motorcycle on a suitable stand.
•Make sure that the motorcycle is upright.
2. Check:
•Brake fluid level
Below the minimum level mark a➔Add
the recommended brake fluid to the prop-
er level.
[A] Front brake
[B] Rear brake
WARNING
•Use only the designated brake fluid. Other
brake fluids may cause the rubber seals to
deteriorate, causing leakage and poor
brake performance.
•Refill with the same type of brake fluid that
is already in the system. Mixing brake flu-
ids may result in a harmful chemical reac-
tion, leading to poor brake performance.
•When refilling, be careful that water does
not enter the reservoir. Water will signifi-
cantly lower the boiling point of the brake
fluid and could cause vapor lock.
Brake fluid may damage painted surfaces and
plastic parts. Therefore, always clean up any
spilt brake fluid immediately.
NOTE:
In order to ensure a correct reading of the brake
fluid level, make sure that the top of the reservoir
is horizontal.
CAUTION:
Recommended brake fluid:

DRIVE CHAIN SLACK INSPECTION AND ADJUSTMENT/
DRIVE CHAIN LUBRICATION
3-36
INSP
ADJ
Rear wheel axle nut:
115 Nm (11.5 mkg)
•Turn each adjusting bolt exactly the same
amount to maintain correct axle alignment.
There are marks on each side of the
swingarm. Use these marks to align the rear
wheel.
DRIVE CHAIN LUBRICATION
The chain consists of many parts which work with
each other. If the chain is not maintained properly,
it will wear out quickly. Therefore, the chain must
be serviced regularly. This service is especially
necessary when riding in dusty areas. This motor-
cycle has a drive chain with small rubber O-Rings
between the chain plates. Steam cleaning, high-
pressure washing and certain solvents can dam-
age these O-Rings. Use only kerosene to clean
the drive chain. Wipe it dry, and thoroughly lubri-
cate it with SAE 80 ~ 90W motor oil or special lu-
bricant for O-Ring chains. Do not use any other lu-
bricants on the drive chain. They may contain sol-
vents that could damage the O-Rings.
Recommended lubricant:
SAE 80W/90 engine oil or
special lubricant for
O-Ring chains.
(1) O-Rings
•Loosen the axle nut (1).
•Loosen the locknuts (2) on each side. To tight-
en the chain, turn the chain adjusting bolts (3)
in direction (a). Loosen the locknuts on each
side. To loosen the chain, turn the chain
adjusting bolts in direction (b) and push the
wheel forward.
•After adjusting, tighten the locknuts (2). Then
tighten the axle nut (1) to the specified torque.

INSP
ADJ
 



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.

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)
