Me, I'd not touch a thing if any wiring was damaged out on the trail. Check fittings being 'home' correctly, Yes, but No to messing with damaged wires.
Heck, when I did the Phone holder relocation set up for my mate(s), it was Completely down to them to sort out the wiring in terms of if it could be routed to suit the position they were going to be in. Their bikes, and I sure as hell was Not going to mess with wiring on their E wonder (and that, they truly Are - I love the bloody things, especially since I didn't have to pay for them) bikes.
If I had to push a Varg, for more than a few meters, I'd quickly dismount the chain - because, as you say, they drag when pushing.
Bit of a bastard of a thing, in that regard.
I'd take the few seconds to do so. And the Varg, has one of the easiest / quickest axle loosening / popping out of the adjuster block set ups in All Motorcycling
Another example of My abundance of caution is with the same group of mates (I've now a group with 5 Starks (lucky me, as I get to ride them - Happy, Happy, Joy , Joy!) wanting me to do Aluminium 'Rock Crusher' bash plates for the bikes., like I do for 'normal' bikes.
There's No Way I'll make such a thing to attach to what I think is a Magnesium Alloy , or Other Alloy Battery case. I'll leave them to take such a risk - they are currently chasing up real Carbon Fibre plates for their use - I understand the std ones are 'edible' . Their risk, going for something stronger, that may transfer too much shock to the battery case ----------------
It's a Torx on the SA, and front axle 'Nut /Bolt - but I used a Hex key, with No slop - can't recall the size.
By the way, a couple of my mates, being rather cashed up, are chasing up / getting Ti Bolt sets. I've no real idea who they will be from, Pro Bolt / Doc Wobb, etc, etc? They may resort to commissioning them from a manufacturer / engineering firm.
Some just want body work / smaller fittings bolts, though, at least one is going for pretty much the Entirety of bolts etc - as in Axles, Swingarm bolt, Motor mount bolts. As I said, they are Rather cashed up individuals. I'm not sure what heads they are trying to get - I do know that they Won't be Torx heads. I don't really have a problem with Torx - but they, collectively, do. I'm not sure how appropriate / usable 'Nut' heads will be, so they may be kits with them, or Hex key heads, or a mix.
I'll post the supplier up when / if they get them. They may just start their own Brand.
