A tyre that is repaired, either temporarily or permanently, will have
lower speed and performance limits than a new or undamaged tyre.
A temporary repair can sometimes be made in an emergency situation.
However, since a temporary repair may not hold, you must ride very
slowly, preferably without any cargo, and have the tyre replaced or
permanently repaired as soon as possible. (For more information on
temporary repairs, see If You Have a Flat Tyre, page 188 .)
A permanent repair, such as an internal plug patch, can be made if a tyre
has only a small puncture in the tread area. However you may not be
able to safely carry as much weight. If you choose to have a tyre
repaired, be sure the repair work is performed by a professional.
If you have a tyre professionally repaired at a non-Honda facility, we
recommend that you have the work checked by your Honda dealer.
