Tires & Tubes
The tires 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.
When replacing, use the original equipment tires or
equivalent tires of the same size, construction,
speed rating, and load range as the originals.
The recommended tires for your motorcycle are:
Whenever you replace a tire, remember:
• Have the wheel balanced after the tire is
installed.
• Have the tire replaced by your dealer if
possible.
• Have a new tube installed whenever a tire is
replaced. The old tube will probably be
stretched. If installed in a new tire, it could fail.
If you have a tire professionally replaced at a non-
Honda facility, we recommend that you have the
work checked by your Honda dealer.
