    Hey All!

    As you can tell from the username, I own a 2021.  Ever since my first ride, I notice that the rev's at idle bounce (fluctuate) between roughly 1200 and 1700 RPM's.  Always like this, regardless of engine temp.  I've never owned a BMW before and I haven't seen any other threads on here about this phenomenon.  Just took her in for the "600 mile" service and the techs didn't mention anything.  Thoughts? 

    Thanks!

    Hey mate yep my 2021 M-sport is like that two I asked BMW and we looked at the Demo bike and that was the same, something to do with the Air fuelling and the new euro 5 emissions.

    If it was an old school bike with carbs I'd have the vacuum gauges and sync the carb's!

    Yup! indeed I'm not that impressed to be fair I'm hopping if we all make a fuss they'll do a software update.

    I’d be happy if they could stop it stalling when coasting up to a junction…
