Looks like the specs have changed for the new Amsoil.
20/40 meets API SM, JASO MA, API GL-1 specs and now backed by Amsoils Secure Warranty. (different than the 10w40)
10/40 meets API SG, CG-4, JASO MA/MA2, ISO-L, EMA2, API-GL1 And no mention of secure warranty. Many more specs covered here.
It appears that Polaris may have made changes to 2013 and above Victory and Indian bikes as Amsoil claims the new formula is for 13 and newer models. Older bikes can still use the recommended 10w40
