1operator and may limit control
ability, therefore, such accesso-
ries are not recommended.
 Use caution when adding electri-
cal accessories. If electrical ac-
cessories exceed the capacity of
the motorcycle’s electrical sys-
tem, an electric failure could re-
sult, which could cause a
dangerous loss of lights or engine
power.
Aftermarket Tires an d Rims
The tires and rims that came with your
motorcycle were designed to match
the performance capabilities and to
provide the best combination of han-
dling, braking, and comfort. Other
tires, rims, sizes, and combinations
may not be appropriate. See page 6-16
for tire specifications and for informa-
tion on servicing and replacing your
tires.
Transportin g the Motorcycle
Be sure to observe the following in-
structions before transporting the mo-
torcycle in another vehicle. 
Remove all loose items from the
motorcycle.
 Confirm there are no fuel or oil
leaks.
 Shift the transmission into gear.
 Secure with suitable straps that
are attached to solid parts of the
motorcycle, such as the frame or
upper front fork triple clamp. Do
not attach to turn signals, cowl-
ings and fairings, or any other
parts that can break. Choose the
location for the straps carefully so
the straps will not rub against
painted surfaces during transport.
 The suspension should be partial-
ly compressed by the tie-down
straps so that the motorcycle will
not bounce excessively during
transport.

to the correct operating clearances.
During this period, prolonged full-throt-
tle operation or any condition that
might result in engine overheating
must be avoided.
