Tube Replacement
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.
Tire Replacement
The tires that came on your CR were designed to
provide a good combination of handling, braking,
durability, and comfort across a broad range of
riding conditions.
Front 80/100-21 51M
Rear 110/90-19 62M
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.
