Tires
A permanent repair, such as an internal plug patch, can be made if a tire has only
a small puncture in the tread area. With such a repair, you should not exceed 50
mph (80 km/h) for the first 24 hours, or 80 mph (130 km/h) at any time
thereafter. In addition, you may not be able to safely carry as much weight. If
you choose to have a tire repaired, be sure the repair work is performed by a
professional and that the wheel is balanced before you ride.
If you have a tire professionally repaired at a non-Honda facility, we
recommend that you have the work checked by your Honda dealer.
Tire Replacement
Refer to Safety Precautions on
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.
