That's because the FJR is designed to run on 87, so there's no benefit to use higher octane.Well according to the experts here at FJRforum, High(er) Octane doesn't give any more power than the lower grade fuel. We had this run around back awhile ago and the thread went on and on........No it's not...With 87, the bike will run just fine. The knock sensor will prevent the bike from making full power, just like in most high compression modern cars. The bike can't reach full potential until 89 or better is used.That's a change from BMWs of past, then. Thanks for the update.
So maybe they should rank bikes according to the fastest ST using regular fuel. Of course, that would be stupid too.
This of course is different if a engine is designed to run on 91 octane.
