Tires
The recommended tires for your motorcycle are:
BRIDGESTONE BTO2OF F

DUNLOP D220FST L
BRIDGESTONE BT020R F

DUNLOP D220ST L
Whenever you replace a tire, remember:
Have the wheel balanced after the tire is installed.
Have the tire replaced by your Honda dealer if possible.
If you have a tire professionally replaced at a non-Honda facility, we
recommend that you have the work checked by your Honda dealer.
Important Safety Reminders
Do not install a tube inside a tubeless tire on this motorcycle. Excessive heat
build-up can cause the tube to burst.
Use only tubeless tires on this motorcycle. The rims are designed for tubeless
tires, and during hard acceleration or braking, a tube-type tire could slip on
the rim and cause the tire to rapidly deflate.
Do not install a bias-ply tire on this motorcycle. Mixing bias-ply and radial
tires can adversely affect handling and stability.
Do not install car tires on this motorcycle. During installation the tire may
separate from the rim with enough force to cause serious injury or death.
When replacing tires, use only the recommended tires as shown above and on
the tire information label. Use of other tires on the model equipped with ABS
may impair proper ABS function. The ABS computer works by comparing
wheel speed.
Non-recommended tires can affect wheel speed and may confuse the ABS
computer.
