If You Have A Flat Tire; Should You Repair Or Replace A Tire Or Tube; Emergency Front Wheel Removal/Installation - Honda CRF450L 2019 Owner's Manual & Off-Road Handbook

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.
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.
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.
Should You Repair or Replace a Tire or
Tube?
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.
