Adjusting the front fork This front fork is equipped with air
valves for adjusting the spring rate.
EW000035
WARNING
@ Always adjust both fork legs equal-
ly, otherwise poor handling and loss
of stability may result. @
Adjust the spring rate as follows.
1. Elevate the front wheel by placing
the motorcycle on the centerstand.NOTE:@ When checking and adjusting the air
pressure, there should be no weight on
the front end of the motorcycle. @2. Remove the air valve cap from
each fork leg.3. Check the air pressure in each
fork leg with an air pressure
gauge.
NOTE:@ An optional air pressure gauge is avail-
able at a Yamaha dealer. @4. To increase the spring rate and
thereby harden the suspension,
increase the air pressure with an
air pump or compressed air. To
decrease the spring rate and
thereby soften the suspension, de-
crease the air pressure by pushing
each valve stem down.

WARNING
@ Because loading has an enormous
impact on the handling, braking, per-
formance and safety characteristics
of your motorcycle, you should keep
the following precautions in mind. l
NEVER OVERLOAD THE
MOTORCYCLE! Operation of an
overloaded motorcycle may re-
sult in tire damage, loss of con-
trol, or severe injury. Make sure
that the total weight of rider, pas-
senger, cargo, and accessories
does not exceed the specified
maximum load for the vehicle.
l
Do not carry along loosely
packed items, which can shift
during a ride.
l
Securely pack the heaviest
items close to the center of the
motorcycle and distribute the
weight evenly on both sides.
l
Adjust the suspension and tire
air pressure with regard to the
load.
l
Check the tire condition and air
pressure before each ride.
@
Tire inspection
The tires must be checked before each
ride. If the center tread depth reaches
the specified limit, if the tire has a nail
or glass fragments in it, or if the side-
wall is cracked, have a Yamaha dealer
replace the tire immediately.CE-08ENOTE:@ The tire tread depth limits may differ
from country to country. Always comply
with the local regulations. @

Lubricating the rear
suspension The pivoting points of the rear suspen-
sion must be lubricated at the intervals
specified in the periodic maintenance
and lubrication chart.
EAU02939
Checking the front fork The condition and operation of the front
fork must be checked as follows at the
intervals specified in the periodic main-
tenance and lubrication chart.
To check the condition
EW000115
WARNING
@ Securely support the motorcycle so
that there is no danger of it falling
over. @Check the inner tubes for scratches,
damage and excessive oil leakage.To check the operation
1. Place the motorcycle on a level
surface and hold it in an upright
position.
2. While applying the front brake,
push down hard on the handle-
bars several times to check if the
front fork compresses and re-
bounds smoothly.
EC000098
CAUTION:@ If any damage is found or the front
fork does not operate smoothly,
have a Yamaha dealer check or re-
pair it. @
Recommended lubricant:
Lithium-soap-based grease
(all-purpose grease)
