Things have changed in Cali since 1984, Trimapa. When I first started riding in the mid-1960's, no special license was needed for the bike. The driving test was simple, the hardest part for most was parallel parking.
These days you must pass a training course (MSF or similar) before you go to the DMV. That will get you a 'learner's permit' that is restricted to daylight hours, no passengers, and no interstate/freeway riding. However, there are no tiered displacement/power rules based on age like in the UK. So theoretically, yes, a 16 YO could get a new R1 and kill himself doing wheelies in a local school parking lot...with his Dad watching. Happened nearby, just a few years ago.
I call it evolution in action.
Lighter makes it righter!
