    Varg Silent Passing Issues

    How close to the handlebar grip did you mount your power/map button assembly? If there is enough space a horn button might fit there nicely. Then, as stated before, a sur-ron horn could work.

    Varg Silent Passing Issues

    Here is a horn on an Alta. Seems OK?

    Thank you. FYI, production is proceeding; there is no production stop. In the case of Marley I doubt that is an inverter issue. ECR was an inverter issue (looks to be IOC circuit but can't be sure until we inspect it). With Marley it looks like the bike is simply failing to turn back on after...

    Thanks. Like I said, I agree on the transparency, but I am engineering and have no influence on that. Ramp up is proceeding. If I posted the numbers I would get chewed out so I won't. What I can say is that I am not disappointed with how things are going. That is as much as I can say. I hope it...

    I clearly stated I am the most senior electronics guy. Go back and check if you like. As for being the spokesperson, I remember you complaining about the battery not being hot swappable. I told you the reasons for that and said if it bothered you to not buy the Varg. To get something like a...

    I am NOT a stark spokesperson. I never posted any delivery date estimates or production ramp up estimates. I am not that stupid. If you have technical questions I am happy to respond to the extent I can.

    I normally don't stoop to the level of personal attacks. But in your case I will make an exception. First. Your inability to read between the lines and take a hint is astounding. You would be much more at home on VitalMX. Second, the Varg is a ground up bike including motor, all electronics...

    Question about Stark charger 240v adapter: is neutral required?

    First question, yes. Correct. Second question. It will work on 110V and draw about 15A, so power draw just above 1.6kW.

    To all those bitching about the lateness... It is a software controlled machine. The software is late. If people are happy with how it performs now just imagine once the software gains features and approaches maturity ;)

    Question about Stark charger 240v adapter: is neutral required?

    There is only one charger. For 3.3kW the charger wants 220 - 240V range. It does not care if you are in Europe and have 230V with respect to neutral and earth or in the USA and have 240V center tapped. All it wants is 220 - 230VAC. Remember, in Europe there is no hot and neutral. When you push...

    Because I don't ride single track. And I am not marketing and am not in a position to organize such a video. I am drive system engineering. What I can do is show you the math compared with an Alta so that someone on this forum who rides an Alta single track can give you a range estimate and then...

    If the weight is a deal breaker then fine, I can understand that. However, the new battery pack gives you more range even with the extra 8kg. The 118kg Varg with the new battery pack will go _further_ in every use case than the "advertised 110kg Varg" with the old battery pack. If you look at...

    When we put it on the scale it was 118kg, so 260lbs. So pretty much identical to a MXR. So the weight is a significant miss. However, the battery pack is _much_ better than the original one promised. The difference is much more than the 6.0 to 6.5kwh implies.

    For MX you don't really feel the weight because the lower rotational inertia more than makes up for the extra mass. For your use case the extra weight might be an issue. Then again it might not be -- because it is distributed a bit differently than with an ICE bike. I think it is not possible to...

    Owner's Review Stark Varg - First Customer Review!

    I didn't say the Varg has some different/superior/magical vector control scheme. What I said is that current into the D axis does not only weaken the flux in the air gap. It also generates torque and therefore power. Current into the D axis is not wasted. Here, have a look at the torque and...

    Owner's Review Stark Varg - First Customer Review!

    Your understanding is not correct. Parts of what you say are correct, but certain bits are just wrong and lead you to the wrong conclusions. First, the battery certainly does care which axis the current is going to. Second, thinking of the Q axis as the torque axis and the D axis as the...

    Owner's Review Stark Varg - First Customer Review!

    There is a decimal point. The video was taken a while ago and I just happened to have it on my phone. I didn't do a dyno run for this exchange. At that point (and still at today) the power curve is not perfectly flat. There is an 8% drop from max power to high RPM region. That can be tuned flat...

    Owner's Review Stark Varg - First Customer Review!

    Hi guys. I don't mean disrespect for Mark, but if you look back at his posts he's been pretty negative about the Varg. I would consider it borderline spreading FUD about the bike with statements like "So, it's easy for me to see something like a Varg making an 80hp dyno spike for advertising...

    Owner's Review Stark Varg - First Customer Review!

    This is not some motor from company X connected to company Y's inverter that has no idea how to effectively flux weaken the motor at higher RPM. You can count on one hand the people who designed the motor, designed the inverter, and wrote the vector control software. At work they all sit within...
