Back in December when Zero did a demo tour event at my local dealer, I had the opportunity to talk with the southeast regional sales manager (I'm not using any employee names here as I have not asked them if I could mention their names) at length due to my SR not liking the software update the dealer applied that morning. See the back story and outcome here:

He told me that it was possible and let him know if I when I was out there next time. I did just that and yesterday I had the chance to go.
My wife and I spent about 1 hour and 15 minutes with a very long time employee. I didn't take photos of all the assembly stations as I was asked not to. But some photos were allowed. I also tried not to take photos of employees.
Our first stop was the production line. They have 3 lines. One for the SRS bikes, one for the SDS bikes and one for the FX bikes. The lines are relatively short. They vary from about 4 stations to perhaps 10 stations. They used computer controlled torque wrenches in all assembly stations. Besides dialing in the correct torque, the wrenches can detect whether a bolt is showing signs of cross threading by being too difficult to thread in or too easy to thread in. It will throw up a flag if such conditions are detected and the bike will then be pulled off the line to be sent to an area for inspection and correction.
Bikes built for the US have green build sheets and bikes for Europe have pink build sheets attached to them. All the bikes being built in all lines were pink sheet builds for containers going to Europe. They have already built most of the 2023 US bikes. Those are either in warehouses or at dealers.
We also saw two battery assembly areas. Those are in their own small building separate from the main assembly building for safety reasons. Each battery is water tested in a cell that cycles water over the battery to be sure they are waterproof. The batteries can be fast charged and fast discharged as a stress test on a special machine. I don't recall if every battery undergoes the stress test or not. But when they do the fast discharge, we were told the power from the battery is actually fed back to the grid.
Once each bike is assembled they move on to the dyno room where they are run through a series of tests to be sure they are working correctly. From there they move on to a final QC area and then on to a shipping area where they are crated for shipping.
We also saw multiple subassembly areas where thing like throttles, levers and wiring are applied to handlebars or wiring and lights applied to tail sections. They also have a subassembly area where tires are installed on wheels. Zero is also currently building the motors for the DSR/X in house. That motor is unique to all their other bikes.
Zero also has a repair shop where dealers for around the west coast can send bikes that the dealers are unable to repair themselves. However, Zero is moving to a system of remote regional factory techs that will actually visit the dealers and do repairs at the dealerships. Aside from eliminating the need to ship bikes, this also allows the regional techs to provide training to the dealer techs. My own SR was tended to by the eastern region factory tech when my dealer was unable to solve the issue with my SR over the last couple of months.
We saw various custom bikes such as the two from Huge and one from Deus. We saw the first Zero called an Electriccross and what I think was an XU. Finally we saw a room of demo bikes. Unfortunately, the weather in Northern CA hasn't been great and didn't really lend itself to test rides. I would have loved to take several of the demo bikes out for a spin through the twisty roads around Scotts Valley.
There are about a dozen photos in this imgur album:
