No mention of car or bike just the spec.
Often bike oils quote older lower specs than car oils. Could be due to the cost of type approval tests. I dunno.
Some of the latest long life car oils are very high tech.
But again the trick is being sure a friction modifier is not present. One dose of that and you'll need a new clutch.
But basically, yes bike oil is a big rip off.
