Tires & Tubes
Tire Replacement
The tires that came on your CRF were designed
to provide a good combination of
handling, braking, durability, and comfort across
a broad range of riding conditions.
WARNING
Installing improper tires 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 tires
recommended in this owner's manual.
Front 80/100-21 51M
Rear 100/90-19 57M
Type bias-ply, tube
• Use a replacement tire equivalent to the
original.
• Replace the tube any time you replace a tire.
The old tube will probably be stretched and, if
installed in a new tire, could fail.
