    Ludicrous idea time

    Time for everyone to weigh in on my ludicrous idea.

    Warp 9 motor at 170ish volts set longitudinally in a full size motorcycle chassis. Single sided shaft drive. Transmission to achieve both the offset from centerline and a choice of ratios (but no clutch, so only shifted between ratios at a stop). Batteries and controller TBD, but enough amps to be exciting and enough kWh to reasonably commute. Not a drag/race bike, but powerful enough to stir the imagination. Styling will not follow the stock bike, but will celebrate the electric drivetrain.

    Thoughts?

    Just don't break any parts. BMW replacement parts are expensive. I like your idea, though. Good luck! You might be the first to try anything like this.

    Why not incorporate a clutch? A 2 or 3 speed tranny would be fun!!

    The batteries will have to fit above the motor, which goes against my instincts for weight distribution. There is space, the question just becomes how far I can get on what will fit. You commented on the size of the Tesla modules in another thread - this is the project I was thinking of at the time.

    The transmission has 6 gears, but sits inverted. Weird, but I think it might work. I will have swap the fill/drain holes (i.e. plug the oil fill hole and drill out the drain plug). I might work out a hand shifter linkage instead of leaving it by the left foot peg. I have doubts about being able to fit a clutch properly, so I have ordered some Lovejoy type L-jaw connectors to connect the trans shaft to the Warp 9 output.

    Hmmmm....
    In my mind, a perfect electric dual sport would have 2 gears. One for tight technical single track thru the woods and uphill trails on loose shale and rock or mud, and then second gear for hwy speeds and faster.
    For a street bike, an emc doesn't really need any gears, but if it did, probably only 3 would be needed, 4 at most (200+ mph top end). Is there any way to modify the 6 speed and reduce spinning mass by removing some of the gears?
    I wonder how well an electric motor would mate to an automatic tranny like the Honda dual clutch....
