    I just want to add, and I'm trying real hard not to be snarky, but the fact that they're running very slightly different gearing on two different motors on an AWD vehicle means absolutely nothing in and of itself. Different motors have different V/RPM, different torque curves, and these are different sizes. Of COURSE they need to run slightly different final drive gearing. Lord knows what magic they've decided on to control the torque balance front/back, or why they're using different sized motors, or any number of dozens of questions about this design. To simply conclude they're using different gearing to somehow widen the power band is, in my humble opinion, a little naive at best. The logic behind making the front pull harder or less at a given speed range makes no sense whatsoever, in terms of AWD vehicle handling.

    Beyond that, even if they were, it's an AWD 4W vehicle, with independent motors front and rear. A motorcycle is a 1WD, 2W vehicle and if you're running two motors (which we've seen in many instances) you have no option for independent drivetrains for each of them.

    but wait, so now you made two more new threads about transmissions, when you can't even handle people reading and posting in one of your many old ones
    ....I think you are being overly obsessive
    What don't you understand about keeping a thread on-topic?

    Yes, I made an index thread so you don't have to use our search feature which kind of sucks. You're welcome. And yes, I made a post summing up where we're at in 2018 after real world use, so I can point people who think they have all sorts of great new ideas to it, so they understand a lot of this has been tried.

    Once again, you want to pick a fight, do it with someone else.

    What to do with the six-speed transmission that you are using in your SV650-clone? Install it in an electric concept sportbike to generate some free press. I don't think that bike will ever see the light of day in a Kymco motorcycle showroom - if you could find one outside Asia.

    Ah. The age-old question. Just because you can do something, should you?

    "That said, 6 gears is probably too many. After a few years of hashing the subject out on the forums, the conclusion I came to was that you maybe need 2 speeds, OK, three. Motorcycle.com agrees: “After now having twice tested the Brammo Empulse R we are convinced that six gears is, at least, three gears too many. It’s our opinion either a Low/High or Low/Mid/High transmission will more than suffice.”

    If one has a motor mounted above the gearbox (Brit's term for a "transmission"), it is necessary to transmit the power from the motor down to the gearbox and then back to the rear wheel. Using a Harley 4 speed gearbox, one can use 3rd & 4th for normal riding, while 1st gear comes in handy for loading up onto a lift or
    trailer. I'll "PM" you with a few photos. Regards, Biker Bob........
