    Air intake noise, C650GT

    Have the later editions of the scooters addressed the air intake noise? My GS is ever so much quieter.

    Cool

    OK I'll bite, what noise, we have a early production model intake is silent, exhaust sounds like a lawnmower though. Any concerns remove right side plastic and make sure air filter IS installed!

    Filter is in place. Also have checked to see that the air intake track is complete and in place.
    I have a five minute 8% grade, at 35 to 40 miles per hour grade that puts a load on the engine. Sounds not unlike a Ducati that I had with an open air box.
    Yes, ear plugs work, but for around town that is a PITN.

    What makes you think it's an intake noise and not just the tractor-like noise they all make?

    Have you compared it to other C650s and heard a difference?

    Have you noticed what RPM range the noise occurs, CVT trans may be shifting down, engine working harder.
    I have had my wife's 650 up to some pretty crazy speeds, didn't notice any intake noise, lots of wind noise though at 105 mph

    I'll just chalk it up to the "tractor like noise" that has been mentioned in several articles. Was hoping that there would be a fix. Guess I'll wait for the electric version.

    Haha, OK. The best thing would be to compare it to other C650s and then you'll know if there's something amiss or just BMW's engineering.

    Cool

    I kinda think your hearing the outboard motor sound. If your in SOCAL you we can compare the sound between bikes
    Drilled the exhaust out on my 1600, sure sounds better, tempted to try it out on brides 650, what a lame sound, not willing to spend big bucks on the after market exhaust

    Outboard motor, yes you are correct. Had an eighteen hp Johnson, water-ski and all. Great times.
    I road the demo, probably a first edition as well, much the same noise.
    My 8% hill and speed is the perfect combination for the excessive noise.
    I'll go around the back way a little quieter, if longer.
