I can tell you from experience that if you don't have the right VIN with 17 digits and with correct numbers and letters, you will get booted out of the DMV office when you try to register the vehicle. However, I believe that there is a way to get around their regulations (such as for home-built and off-road-only vehicles), but that requires specialized knowledge and DMV connections. I have heard that there are a few companies that make a living registering weird vehicles for on-road usage, such as the stuff that Jay Leno owns.
However, it sure sounds to me that Lightning must have received some sort of manufacturer's experimental exemption for their current Strike models, such as when a new pre-production model is being tested on public roads by a vehicle manufacturer - like when Zero was testing the SR/S, as an example.
What retail customer would buy a vehicle with temporary guts that don't meet the advertised specifications and likely comes with a promise that they might be changed in the future once the bugs are worked out of the design and what sort of guarantee would they receive for the vehicle?
And if something misfires while they are riding the motorcycle and the owner is hurt, hurts someone else, or causes third-party damage, I hope Lightning has a good product liability insurance policy. There are a ton of ambulance-chasing lawyers advertising on TV who would love to take the case and sue a vehicle manufacturer for damages - such as Russ Brown "The Motorcyclist's Attorney".
