If You Have a Flat Tire
(cont’d)
Taking Care of the Unexpected 167
A flat tire is always unwelcome, especially if you
are far
from help. If you think you are losing air, or
you hit a pothole or hard object, pull safely to the
side of the road so you can inspect the tires and
assess the situation. (Be sure to park on a firm,
level surface and use the side stand for support.)
You should examine the tire treads and sidewalls
for foreign objects or damage.
If a tire has major damage or the bead has come
loose from the rim, there is probably not much you
can do except have your motorcycle transported to
your dealer or other qualified service facility. Even
with a simple puncture, this may be the safest and
least troublesome solution. For transporting
instructions, see page 158
Honda does not recommend that you make a
temporary repair to a tube-type tire. However, if
you decide to make a temporary repair so you can
get to a service facility, ride cautiously at reduced
speed and have the tube and tire replaced before
you ride again.
Due to the uncertainty of any temporary repair,
you should ride slowly (not over 30 mph, 50 km/h)
and carefully (preferably without a cargo) until the
tire and tube are replaced. Stop frequently and
check the air pressure. If the tire is losing pressure,
it may be unsafe to continue riding. As the tire gets
low, it will affect the handling of your motorcycle
(especially with a cargo) and it may overheat and
blow out.
We strongly recommend that you replace, not
repair, any tire or tube that is punctured or
damaged, even if the tire has only a minor
puncture. For a full discussion of repairs and
replacement, see the text beginning on page 127.
Refer to Important Safety Precautions on page 33.
We recommend wheel removal be done only by
your dealer or another qualified mechanic. Do not
attempt to remove the wheel on your own. Wheel
removal requires mechanical skill and professional
tools.
When removing and installing the wheel, be
careful not to damage the wheel speed sensor and
pulser ring (1).
Removal
1. Place your motorcycle on an optional
workstand or equivalent support with the front
wheel off the ground.
2. Remove the disc cover (2) by removing disc
cover socket bolts (3).
3. Remove the speed sensor wire guide plate
screw (4) and guide plate (5). Remove the speed
sensor mounting bolt (6) and speed sensor (7).
4. Remove the front axle nut (8) and loosen the
axle pinch bolts (9) on both forks. Pull the front
axle shaft (10) out of the wheel hub and
remove the front wheel and side collars (11).
Avoid getting grease, oil, or dirt on the disc
or pad surfaces.
Do not pull the brake lever while the wheel is
off the motorcycle.
WARNING
Riding your motorcycle with a temporary
tire or tube repair can be risky. If the
temporary repair fails, you can crash and
be seriously injured or killed.
If you must ride with a temporary tire or
tube repair, ride slowly and carefully and
do not exceed 30 mph (50 km/h) until the
tire or tube is replaced.
