Lubricating the front and rear
brake leversZAUM00**ZAUM00**
The pivoting points of the front and
rear brake levers must be lubricated
at the intervals specifi ed in the period-
ic maintenance and lubrication chart.
EAU23095
Checking and lubricating the
cablesThe operation of all control cables
and the condition of the cables should
be checked before each ride, and
the cables and cable ends should be
lubricated if necessary. If a cable is
damaged or does not move smoothly,
have a Yamaha dealer check or re-
place it.
WARNING! Damage to the outer
housing of cables may result in
internal rusting and cause inter-
ference with cable movement.
Replace damaged cables as soon
as possible to prevent unsafe
conditions.
[EWA10711]
Recommended lubricant:
Yamaha Chain and Cable Lube or
engine oil
EAU23114
Checking and lubricating the
throttle grip and cableThe operation of the throttle grip
should be checked before each ride.
In addition, the cable should be lubri-
cated by a Yamaha dealer at the inter-
vals specifi ed in the periodic mainte-
nance chart.
The throttle cable is equipped with a
rubber cover. Make sure that the cov-
er is securely installed. Even though
the cover is installed correctly, it does
not completely protect the cable from
water entry. Therefore, use care not to
pour water directly onto the cover or
cable when washing the vehicle. If the
cable or cover becomes dirty, wipe
clean with a moist cloth.
