The load index refers to the maximum allowed weight. The tires we install on our motorcycle must have a load index that can support the motorcycle's gross weight. The choice should always be made according to the information provided by the manufacturer of our motorcycle.

R

The speed index is the maximum speed for a tire when it has the correct pressure and is used under load. It is represented by a letter at the end of the dimension on the side of the tire, after the load index. For example, a tire with an R speed index has a maximum speed of 170 km/h.
