Honda CRF450R 2023 User Manual

Have your tyres replaced by your dealer.
For recommended tyres and air pressure, see
“Specifications.” 2 P. 71
Follow these guidelines whenever you replace
tyres:
● Use the recommended tyres or their
equivalents of the same size, construction,
speed rating, and load range.
● Remember to replace the inner tube
whenever you replace a tyre. The old tube
will probably be stretched, and it could fail if
installed in a new tyre.
● If a tube is punctured or damaged, you
should replace it as soon as possible. A
repaired tube may not have the same
reliability as a new one, and it may fail while
you are riding.
Use a replacement tube equivalent to the
original.
3WARNING
Installing improper tyres on your
vehicle can adversely affect handling
and stability, and can cause a crash in
which you can be seriously hurt or
killed.
Always use the size and type of tyres
recommended in this owner's manual.
