These are not special Construction. They will be VIN#, and ID as UTV’s just like a Polaris or Can Am.
The only possible hiccup is if CARB is not final. But it does not have to be published to be final. Just because you can’t find it does not mean it’s not done. It’s been said due to “Covid” that CARB was behind. But that did not keep Polaris from selling the Pro R which was not published at the time they hit the dealer floors. But was said to be CARB compliant when it was on the dealer floors.
Maybe you weren’t in the OG thread, but I had posted that Speed was using the same company that Can Am and Arctic Cat uses to get their vehicles through the CARB /EPA process. So it’s not Todd & Robby trying to figure it out. It’s an actual company and this is what they do. The majority of the process is documentation paperwork and filing the docs.
