Whether or not it is safe to ride on a plugged motorcycle tire depends on the location and size of the plug, as well as the type of tire and the conditions in which the motorcycle will be ridden. In general, a properly installed plug can provide a temporary fix for a punctured tire, but it is not a permanent solution.
If the plug is installed correctly and the puncture is in a non-critical area of the tire (such as the tread), it may be safe to ride on the tire for a short distance until you can get to a service center to have the tire properly repaired or replaced. However, if the puncture is in the sidewall of the tire or the plug is not installed correctly, riding on the tire can be dangerous and could result in a blowout or other serious failure.
Additionally, it is important to keep in mind that a plugged tire will not perform as well as a new or properly repaired tire, and it may be more susceptible to failure in extreme conditions such as high speeds or rough terrain.
In short, if you have a plugged motorcycle tire, it is best to have it repaired or replaced as soon as possible by a qualified service technician. Riding on a plugged tire is not recommended, and could put you at risk of a tire failure or accident.
