In checking what is needed for obtaining a title in Colorado, there is no documentation of the NHSTA stuff/stickers. Not sure who is going to be looking for them.

This is what is needed at the DMV:
* You need an MCO. And, I think if it says Motorcycle rather than Dirt Bike, then this is good thing.
* You apply for a title & registration on a form (that has no such place to enter anything about EPA, NHSTA, etc).
*You have to have a VIN inspection, which is just that, nothing more than what is says....making sure the VIN is OK.
* You need insurance.
* You need an ID.
