I came to California with my RM250 and have been attempting to dissect the regulatory requirements. It's a trip, bro.
[a nod to the other thread where people gave me some great riding area info).
I see this:
Racing Motorcycles (CVC §38088)
OHV motorcycles used solely in organized racing or competitive events on a closed course such as speedways, racetracks, or defined routes of travel (on or off highway) cannot be registered. However, they may be issued a permit for a fee that allows transportation to/from course events. A closed course is not available for vehicle access by the general public other than event participants (CVC §38014). The permit is a sticker that must be mounted on the vehicle in a clearly visible location and remains valid until the vehicle is sold or dismantled.
I have heard about people being pulled over for not having vent hoses on their gas cans in their trucks. In 40 years of motocross I have never heard anything about needing a permit to carry a dirt bike in a truck.
Now, before this devolves into a "Commiefornia" bashing session- I have lived all over the world, and [Northern] California is the greatest and most amazing place I have ever lived. By far.
It's impossible for a corporation or government to love you or care about you.
