    There is an awful lot of rhetoric spoken about this bike, mainly by the manufacturer.

    It's already significantly more expensive than the Zero and the handling is going to be 'interesting' given...

    The bike won't be straight. Worth getting it on a jig before you spend too much more money on it.

    Easiest way is with a wheel alignment tool that bolts to the rear wheel (not the tyre) and shines a laser up either side on to a marker board.

    The cheap way, assuming your local bike shop doesn't...

    Forum Tech problems

    Trying to login I get an error message saying 'invalid redirect'.

    Trying to post a reply I get "Warning: Only variables should be passed by reference in ..../newreply.php on line 389"

    Any ideas?

    Shame they didn't include more info on their testing. The 0-60 and 1/4 mile runs would include gear change time on what they reckon to be a clunky Brammo gearbox, thus slowing it down depending on...

    I remember reading a piece in Fast Bikes magazine soon after I learnt to ride. It was talking about how all these random accidents always appeared to happen to the same people. They may not have ben...

    If you can afford an M170 and the extra for the toolkit then I guess anyone can have it.

    I doubt they supply source code for everything, more likely to be libraries for the core functionality...

    The original discussion was that anything is possible and that most controllers either cannot match the functionality or require too much work to bring it to the same level. It appears to have turned...

    Why would you want to programme a controller when you can have the algorithms in a separate box that be plugged in to almost anything?

    How much time and money gets wasted with everyone developing...

    The main reason for doing parallel first as I understand it is that any BMS can view the smaller parallel pack a single cell so if you don't want to monitor every individual cell you can at least...

    I agree, there are some quite impressive controllers but do you really want the controller to monitor the battery temperatures and voltages, map the throttle input to the torque requirements, take...

    Yep, I'm talking about a stand alone ECU, in this case a Motec M170 that we used on our British SuperBike Suzuki GSXR1000.

    Without a differential every electric car needs a degree of torque vectoring or it won't make it around the corners very well.

    It's most common in the 'one motor per wheel' set up and can be very...

    This is turning in to quite an interesting discussion. Clearly at the outset there were some assumptions as to quite what the implementation was looking like which may have skewed the understanding...

    What's the actual question?

    On an ICE SuperBike, just as on an electric SuperBike the link between the throttle and the engine is the ECU. The two do not have to have a linear relationship, hell,...

    I know that's why we spend so much time working on the traction control for our petrol SuperBikes.

    You would be surprised just how complicated the power/torque delivery can be with 3D maps to...

    That may be the case with some of the smaller electric bikes but don't forget you are effectively comparing an SV650 with a 600 inline four. The torque from a big electric bike is far greater than a...
