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. Place the motorcycle on the side-
stand.NOTE:_ When checking and adjusting the air
pressure, there should be no weight on
the motorcycle. _
2. Remove the air valve cap from
each fork leg.
3. Check the air pressure in each
fork leg with the air pressure
gauge included in the owner’s tool
kit.
4. To increase the spring rate and
thereby harden the suspension,
increase the air pressure with an
air pump. To decrease the spring
rate and thereby soften the sus-
pension, decrease the air pres-
sure by pushing each valve stem
down.
EC000012
CAUTION:_ Never exceed the maximum air pres-
sure, otherwise the front fork oil
seals may become damaged. _5. Securely install the air valve caps.

5-PRE-OPERATION CHECKSThe condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or loss
of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual inspec-
tion, to check the following points before each ride.
EAU03439
