This chapter includes all information necessary to perform recommended inspections and adjustments.
These preventive maintenance procedures, if followed, will ensure more reliable vehicle operation and a
longer service life. The need for costly overhaul work will be greatly reduced. This information applies to
vehicles already in service as well as to new vehicles that are being prepared for sale. All service techni-
cians should be familiar with this entire chapter.

NOTE:
Check the steering head for looseness or binding
by turning it all the way in both directions. If it
binds, remove the steering axle assembly and
inspect the steering bearings.
Refer to “STEERING HEAD” in Chapter 6.
TYRE INSPECTION
WARNING
•Tyre pressure must be checked when the
tyres are at ambient temperature. Pressure
must be adjusted according to the total
weight of luggage, driver, passenger and
accessories (fairings, bags, if approved for
this model) and speed of the motorcycle.
•A list of tyres approved for this model fol-
lowing severe testing by Yamaha is provid-
ed. There can be no guarantee of safe road-
holding if a combination of tyres different
from those indicated is used.
•Front and rear tyres must have the same
design and be of the same make.
•The use of valves and valve stems other
than those indicated might cause the loss
of tyre pressure at high speeds. Use only
original or compatible spare parts.
•Replace the valve cap securely to prevent
losses of tyre pressure at high speed.
