Wheel & Tyre Replacement
The tyres that came on your motorcycle were
designed to match the performance capabilities
of your motorcycle and provide the best
combination of handling, braking, durability
and comfort.
Installing improper tyres on your
motorcycle can affect handling and
stability. This 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.

Used tyres should not be installed if the
previous usage record is unknown.
The recommended tyres for your motorcycle
are:
Front: CRF125F: 70/100-17M/C 40M
CRF125FB: 70/100-19M/C 42M
Rear: CRF125F: 90/100-14M/C 49M
CRF125FB: 90/100-16M/C 51M
Type: bias-ply, tube
The recommended wheels for your motorcycle
are:
Front: CRF125F: 17 × 1.4
CRF125FB: 19 × 1.4
Rear: CRF125F: 14 × 1.85
CRF125FB: 16 × 1.85
Whenever you replace a tyre, use one that is
equivalent to the original and be sure the wheel
is balanced after the new tyre is installed.
Also remember to replace the inner tube
whenever you replace a tyre. The old tube will
probably be stretched, and if installed in a new
tyre, it could fail.
