I'm not an expert but I have learnt something about those batteries and I doubt that they could have available anything so different from what we have. Just check the specifications of the battery of the Ducati V21L used in MotoE, where probably they are willing to spend more money: the energy...

Now that I think about it, I've seen it on circlip mounts as well; probably you are right.

I never buy aftermarket front sprockets because I fear that they may damage the countershaft because of some characteristic of the splines. For example, the splines may be too hard or have an excessive shape error or the wrong play.

I like the idea of considering in which rpm range the motor is the most efficient, but I think that the AI has confused things here, since as far as I know the Varg motor is a purely permanent magnets motor, while the permanent magnets reluctance motor is a special hybrid solution used in...

What about this style @ 4:50?

I agree, besides the speed on our speedometer is based on the wheel speed and I think that the reason for which I have recorded top speeds like 80 - 90 mph is revving in the air. I think that in motocross wheel slippage is too high to rely on wheel speed for power curves. Hopefully if we will...

The following information holds good for my MX; I guess it should be the same for the EX. If you feel like leaving the motorcycle unattended while charging, which is against what is recommended in the manual, then you can just leave it plugged and set the maximum charge in the Varg app, so it...

I'm not surprised: their policy about this, which to me looks completely understendable, is that the user should never open a battery. You've said that you repair EV batteries for a living and I guess you can confirm that opening a Stark Varg battery could result in someone dying. I am not an...

I guess so, but on the other hand one would tend to think that you can do wonders with electronic devices since it's "just" a matter of programming them, so physical modifications should be needed seldom. The throttle could be adjusted so that up to a certain opening it behaves like in a certain...

First of all, what I'm going to state is still moot since I've never set any power curve in my life. The top speed of the Varg EX according to the manual is 129 kmph, I guess at 14K rpm, so 140 kmph @14 K rpm approximates reality, then you can roughly say that every 1K rpm is roughly 10 kmph...

Here is a more qualified opinion of someone who also explains how electric motorcycles are somehow superior for FMX. Yes, he's signed a contract with Stark Future, but looking at the performance of the Varg in FMX I'd say that he's being honest: Here is my opinion, directly copied and pasted...

In some interview the CEO A. Wass said that there are actually more generations of those Power Tubes. Referring to my previous post, my bike now has 59 hours including 2 or 3 hours of enduro with some rocks and the rear Power Tube hasn't gone flat yet. I am considering bringing a set with me at...

The red line is basically like a dyno chart of a Varg at full throttle. Like you would expect from a synchronous motor, up to half the rpms there is constant torque, which makes the power curve a straight line with some slope, since power = torque * rpm * a constant ane when torque is a...

Not that I feel like doing it right now, but I think that another important piece of data to use for statistics is the total time of the races. We all know how motocross is also about stamina and at least IMO and from my limited experience, since I haven't ridden many bikes for long durations...

Exactly. Those situations are usually pretty uncomfortable and hard to handle when you find yourself involved; they look easier from outside. Typically those guys know many ways to fool you.

Well, you've said that you have worked with 120KV on CT scanners and you surely sound like someone who knows what he's doing, but let's remind everybody that opening such a battery can easily kill the person who does it if this person doesn't have the knowledge and skills or makes a mistake...

I've asked Gemini to explain what a low pass filter would do in this context it and, in its opinion, a low pass filter would basically make the throttle response less aggressive. I guess that the main factor which can make the throttle response right is the reaction time of the rider. Here is...

People try so hard to see the glass half empty for electric dirtbikes. What about a slow rider like me? I'm glad that I can hear incoming people better! Besides, if I'll ever become fast, I can always add an horn like this, 140 dB should be enough...

@fmxxx666: I wish I were allowed to ride in a home garden like yours, maybe building a little ramp for a jump or at least being able to do some figure 8s. Wow, coming back from home after work, training with the bike half an hour, if you have a flat the garage is 5 seconds from you... what a...

Here, @ 14:29, there is an explanation about the spin loss that we experience in the permanent magnets motors like the ones in our Vargs: If you want to try, make sure that the chain guide is wide enough for it; some people have written that it's not if I recall correctly. Anyhow, super...
