Sidewall markings on the tire provide all the information you need about your tire. 

Here are the explanations which will help you understand each marking on the sidewall.  

SPEED INDEX

The speed index marks the highest allowable speed of a tire with loads specified in the load index. Speeds apply to tires in good condition, properly inflated, with permissible specific load and mounted on suitable rims. The speeds listed in the table are the highest permissible speeds and should not be considered as the ordinary speeds.

LOAD INDEX

The load index is the numerical code, which stands for the highest tire load allowed (except for loads at speeds over 210 km/h) at speeds marked with the speed index. When worn-out tires are replaced, make sure that the new tires are of the exactly the same or higher speed index and of load index as specified by the motorcycle manufacturer.
