How do I know if the lubricating oil of my motorcycle meets the JASO standard?

The motorcycle lubricants that meet this standard have a label with the JASO seal and a code. You can check the lists provided by the Japanese Automotive Standards Organization (JASO), which is updated every month. Repsol Moto 4T and Moto 2T products are on that list, which ensures that they meet the required qualities.
