    Is That an Electric Motorcycle?

    Sitting at an in-town traffic signal this morning, a bicyclist next to me turned and asked "Is that an electric motorcycle?" I said no, it wasn't. He said "It sure is quiet. I wish all bikes were that quiet."

    Doesn't have to be loud to be powerful, does it.
    No. Really!

    Denial, mostly. Sometimes West Sacramento
    The new 2011 HD is going to have the exhaust split, half facing forward. Because we all know 'Loud Pipes Save Lives'....

    In the state of Misery for now.
    For an intake/exhaust to be quiet without being restrictive you need volume to store the pulses and then exhaust them in a steady flow.
    The engine and transmission design of the opposed beemers leaves a lot of room under the transmission and behind the alternator for this volume. So a loud aftermarket exhaust adds very little horsepower. It is mostly just less weight. Same for the intake.

    With the slammed to the ground Harley frame,engine, transmission design, they do not have this hidden volume. Quiet and non restrictive intake and mufflers would be big and ugly, so the stock setup is fairly restrictive. Removing it does give them a nice horsepower increase.

    If you got as big a horsepower increase on the beemers there would be a lot more aftermarket exhausts and intakes sold.
