I've indeed found videos of motocrycles having a rear fuel tank catching fire and I'll post some, to put things into perspective, since EV haters are indeed very ready to state they've never seen a gas bike catching fire: but i've also found others of front tank bikes catching fire...

It's hard for me, too to lock the wheel and other people have reported the same.

Isn't the caliper the redundant part? Since its part number is the same for both hand and foot brake, if you have the foot brake you can reuse it. Well, at this point I would say that if someone wants to switch to hand brake, then it's cheaper and better to just buy the master cylinder, the...

Well, we can state some things from what we know. One thing that I find interesting is that, from the pictures, I think that they use a progressive spring for the rear shock instead of using linkages or more shock tilt to get the progression. Explanation for those who need it: generally you...

It's weird, though, that Stark sends the components already assembled if they have to be taken apart again to then change the fluid and replace the copper/aluminum washers. I understand that Stark makes such sub-assemblies for the production line in the factory, where they can be installed...

Here is the routing of a Varg which came with a LHRB; the routing is highlighted in yellow: I suppose that you could try: 1- checking whether the master cylinder can pass between the frame, the VCU and the battery if it does, 2- removing the rear shock and hopefully making the master cylinder...

I agree, it's possible that it's happened because of modifications. When there is a flood for example, especially if salt water is involved, EVs can catch fire, even days after the water intrusion, because of the short circuit generated by the water. I guess that it is possible that there was...

In the battery replacement video tutorial, they first disconnect the CAN BUS and only afterwards they disconnect the orange power cable. I can't see whether that cable was connected while you were using that multimeter. Was it disconnected? In which state was the bike when you disconnected the...

Answering to the fact that there is no voltage, here is a measurement of a disconnected battery, that I discourage to replicate since it's probably dangerous. The measured voltage is the one of the battery. I assume and I hope that the current wouldn't be allowed to flow or I don't see the use...

I think that this is a good general piece of advice, but in the specific case of Stark, IMO they should really take care of their reputation. A lot of people already hate them for no valid reason and surely I don't want those people to have some racing failures to utilize as arguments. Now, I'm...

It's also hard to foresee the battery duration using technical data. One way in which you can try and estimate whether the 7.2 kwh battery of the MX 1.2 would finish an MXGP race is to consider that, ideally, it can provide an average power of 14.4 kw (19 hp) for half an hour (because...

If those 60 miles have been measured with the on-board odometer, and if that odometer works measuring the rotational speed of the rear wheel as I suspect, then the 60 miles value has been affected by the different size of the rear wheel.

They have postponed the introduction of that class: David Luongo postpones MXEP debut. - Get Dirt

Some of you may know that there has been a series named MotoE in which they raced electric sportsbikes and that Ducati has provided their V21L bikes for the latest years. Well, that series has gone on hiatus but Ducati has still made a demonstrator for solid state batteries: It is also the...

One thing to consider is that part of the mechanical advantage is given by the ratio between the radius of the rotor and the radius of the wheel. A Ø 220 mm on a 15" wheel will generate more braking torque than the same rotor on a 18" wheel (you should also add the height of the tyre, but you...

The Formula MC looks like this one except for the fact that this one is for the front brake: MX-ENDURO – Formula SRL

Do you have the Formula or the Brembo master cylinder?

For supermoto conversions of the Varg, I've never heard of anybody using a radial master cylinder for the rear hand brake. I've found these on the internet: from Accossato from Discacciati + the bracket and there are also radial MCs for clutches that may work. For the front brake, I've always...

Well, I've successfully used the old fashion way but only with other bikes: I've never bled the LHRB of the Varg; I just assumed it would have worked, without having ever done it. Now that I think about it, it also has a pretty long brake line.

That's another common method. It has just occurred to me that I haven't pointed out how important it is to make sure that no brake fluid end up on the brake pads because, according to some people, if that happens it can leave a residue that makes them slippery and that is hard to remove. This...
