Let me conclude my wonderful saturday at the track with my Varg by posting some good news that I've found out on their Linkedin profile: Spain: EIB and Stark Future sign a €40 million loan to invest in innovation and new solutions for the electric motorcycle sector

The battery may very well have a 69K waterproof rating, which means that it can resist pressure washing, but not the whole bike has the same rating. Remember that when you totally submerge a Varg under water even the lowest points, i. e. the two contact points of the tyres with the bottom of the...

(y)(y)(y)(y)(y) I love reading stuff like this!!

It's basically like a simplified version of a precharge circuit, but it seems like in your case the resistor is in series with the main circuit and not in parallel with a relay like done usually. What I conclude is that the current going to the controller will always pass through that resistor...

On one hand, I respect the fact that you made sacrifices to afford your Varg. Unfortunately, motorsport in general is pretty unfeasible because of the money and time needed and that's why, sadly, so many people love it but they have to get satisfied of being just fans and not riders, drivers or...

I can perceive your happiness and that's awesome; just a piece of advice: if you can't avoid keeping the charge between the suggested 20% - 80% range -I don't either, it's at 100% when I enter the MX track- at least recharge a drained battery as soon as possible. Now, in one of the local tracks...

I like the idea to have more batteries to reduce heat, not only because of the possibility to turn off that Discharge BMS current control. There is a concept used when calculating the cooling rate of cast parts, like cast iron: the modulus, or volume to heat exchanging surface ratio. If you have...

Well, here this English seller has Guts seats, maybe they can get a Wing seat for your Stark if yiu ask them. GUTS Racing

This statement at 8:19 is pretty interesting: I don't know how much Stark is profitable; maybe he doesn't consider Stark because non road legal dirtbikes could be considered as not being vehicles and because surely they are not part of his competition. Anyhow, apparently this is another...

Italian electric brand Energica confirm bankruptcy Here is an interview of their CTO about the situation, to be translated from Italian: Energica, non tutto è perduto They used to be the MotoE supplier and then they were replaced by Ducati (BTW that V21L looks amazing). I'm sorry for them...

A. Wass talked about fast charging back in this interview released in February; in short, he said that it's possible to safely recharge the Varg more than twice as fast as with the current charger used at 240 V but that they thought that most of the people would use their existing power outlet...

Here is a specific Varg protection: Swingarm guard protection Rtech | Stark Varg

Surely I don't have the same expertise but I think I can answer: 665 lb-ft is the peak torque at the wheel, which doesn't spin at 14,200 rpm: the motor shaft does. Besides, tipycally motors can't reach the peak torque at maximum rpm.

One way in which you can look at power used to accelerate a mass, using high school physics (that's basically what I can do), is to consider it as the difference between the final and initial kinetic energy. You will notice that, for example, the average acceleration from 0 to a velocity v is a...

You are right; compared to English language, here we use commas instead of periods and vice versa, when writing numbers. Sometimes I forget about this differece (I should pay more attention or in different scenarios it could cause some serious misunderstanding when discussing something...

I don't want to be pedantic, but, after having tried to apply that formula unsuccessfully for years with dyno charts and wondering what was wrong in frustration, I once found out that it's an incomplete formula. Actually: Power (W) = 2π • Torque (Nm) • rpm (dimensionless) / 60 seconds...

I actually meant something different: some skilled guys sometimes wheelie through whoops sections, like this: and my question was: what if I wanted to do the same thing without having the skills: do you think that it could be done using a kind of wheelie control which prevents the rider from...

I suck at wheeling intentionally and I can't wheelie through skim whoops like the fast riders can do. Do you think you could create a kind of control that, when someone opens the throttle enough, will keep a wheelie or at least help keeping it in a situation like that? What happens if you set...
