And not a single JASO MA certification mark among them. So, it is just their unsubstantiated claim that these products "meet or exceed" those standards. And again, since API no longer certifies motorcycle oils, and that the former API motorcycle standards are now obsolete, you'll likely not see an API donut on a dedicated motorcycle oil. The JASO mark is about all we can hope for.
Keep in mind the corporate lawyers waiting in the wings at the motorcycle manufacturers just waiting to say that your oil related property loss was due to using non-certified oil. It could happen, never say never.
I have seen dedicated JASO certified motorcycle oils on the shelves of good quality MC dealers and parts/accessory shops. Some of those oils tend to be very expensive as well.
I just recently got rid of a nearly empty bottle of Yamalube 20/50 I used with my old FJR, and I'm quite certain it wore the Jaso MA mark. I'd bet the 3rd party suppliers filling the Big 4 MC brand oil bottles are putting JASO certified oil in those bottles, since the MC manufacturers tell us to use JASO oil in their engines.
