Disagree.
No oil is a "one size fits all" in the wide ranging world of motorcyle engines. Common production motors span from simple thumpers, to [potentially] hot running air cooled twins, to silky liquid chilled 6's.
There are valid reasons the mechanical engineers who make certain engine types may specify a multi-vis 50 such as 10W50 or 15W50 be used.
Personally, I tried Rotella T Triple Protection 15W40 once in a 2013 Ducati. Shifted very poorly (shared sump). Couldn't tolerate it, drained after couple hundred miles. Current mount requires 15W50 meeting API SM and JASO MA2, no exceptions.
