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...

Actualy something that has not been mentioned yet dabout the Varg is the warranty. All Vargs are still under warranty and I personally wouldn't void it replacing the inverter with an aftermarket one. I still wish you good luck with your project, of course, even if most likely I won't participate.

I've just noticed that the swingarm axle doesn't pass through the case of that QS138 70h V3 motor, unlike what happens with ICE engines or with the power unit of the Varg, for example. Wouldn't it be better to build the mounts with steel? Or would it be too expensive to cut it or machine it?

I personally think that keeping the power under control using the throttle is part of the fun of riding and it's a skill I want to keep trained, so honestly I think I wouldn't like it. Never tried it on a motorcycle, though. Since my only electric bike is a Varg and I probably live too far, I...

Rounding the figures and forgetting the 999 €/$, here in Italy: • the Alpha used to cost 14 K € • the 60 HP used to cost 13 K €, which is what I paid including VAT Now on Stark's site I read that there is only the Alpha option, for 12K € including taxes.

What you have said makes sense. Honestly, despite the fact that I don't side with anyone and I only support people when they are right, I am a Stark's fan who tends to support them and when I think about it I am happy to be their fan because they are trying to do something very important to me...

Ok, thank you. They also have a datasheet on their official website with viscosity etc. Is your valving stock?

What oil have you used in the fork with the original valving guys? According to the Specification sheet from Stark's site, 355 cc of the KhL 15-11 oil should be used in each leg and that must be the oil outside the cartridge; I guess that something more than 200 cc of the same oil should be used...

I don't know how much a generator weighs but I strongly believe that the day of the trackday physical efforts, especially before the riding is over, should be avoided, so I like the idea. There is a document named Stark VARG - Specification sheet in the Stark's support section of their site...

Very cool and interesting project. If I were you, in order to decide in which position to install the battery, I would install it provisionally in different positions and then I would check the weight distribution of the bike in those positions, choosing if possible the best one. I like the...

I'd like to share an experience of mine with Hall sensors. Some years ago I borrowed an idea from a video in which F1 drivers trained to think sharply even with high heart rate and physical demand, typical of racing: I made up this workout in which I keep my heart rate in zone two with a...
