specifications and more information on
replacing your tires.
Transportin
g the Vehicle
Be sure to observe the following in-
structions before transporting the vehi-
cle in another vehicle.  Remove all loose items from the
vehicle.
 Point the front wheels straight
ahead on the trailer or in the truck
bed, and choke it in a rail to pre-
vent movement.
 Secure the vehicle with tie-downs
or suitable straps that are at-
tached to solid parts of the vehi-
cle, such as the frame or upper
front fork triple clamp (and not, for
example, to rubber-mounted han-
dlebars or turn signals, or parts
that could break). Choose the lo-
cation for the straps carefully so
the straps will not rub against
painted surfaces during transport. 
The suspension should be com-
pressed somewhat by the tie-
downs, if possible, so that the ve-
hicle will not bounce excessively
during transport.
EAU60590
Further safe-ri din g points Be sure to signal clearly when
making turns.
 Braking can be extremely difficult
on a wet road. Avoid hard braking,
because the vehicle could slide.
Apply the brakes slowly when
stopping on a wet surface.
 Slow down as you approach a
corner or turn. Once you have
completed a turn, accelerate
slowly.
 Be careful when passing parked
cars. A driver might not see you
and open a door in your path.
 Railroad crossings, streetcar rails,
iron plates on road construction
sites, and manhole covers be-
come extremely slippery when
wet. Slow down and cross them
with caution. Keep the vehicle up-
right, otherwise it could slide out
from under you.
 The brake pads or linings could
get wet when you wash the vehi-
cle. After washing the vehicle,
check the brakes before riding.
