Honda cb400 super four User Manual

To safely operate your motorcycle, your
tyres must be the proper type and size, in
good condition with adequate tread, and
correctly inflated for the load you are
carrying. The following pages give more
detailed information on how and when to
check your air pressure, how to inspect
your tyres for damage, and what to do when
your tyres need to be repaired or replaced.
Keeping your tyres properly inflated
provides the best combination of handling,
tread life and riding comfort. Generally,
underinflated tyres wear unevenly,
adversely affect handling, and are more
likely to fail from being overheated.
Overinflated tyres make your motorcycle
ride more harshly, are more prone to
damage from road hazards, and wear
unevenly.
We recommend that you visually check
your tyres before every ride and use a
gauge to measure air pressure at least once
a month or any time you think the tyres
might be low.
Tubeless tyres have some self-sealing
ability if they are punctured. However,
because leakage is often very slow, you
should look closely for punctures whenever
a tyre is not fully inflated.

Using tyres that are excessively worn
or improperly inflated can cause a
crash in which you can be seriously
hurt or killed.
Follow all instructions in this owner’s
manual regarding tyre inflation and
maintenance.
