In the US and Ca. it is all about emission stickers. If you purchased the bike out of country you will not have one that meets the requirements. They cannot be retrofitted.
There are exceptions for Ca. http://www.dmv.ca.gov/forms/reg/reg256f.pdf
You look like you may fit one. Reading it makes me think you will still have to meet DOT requirements. That is about horns, turn signals, headlight dimming etc. I don't know the procedure for that. It sounds like it has to come from a Federal agency. The Department of Transportation is Federal.
A word of warning, as difficult as DMV makes it to import an out of state bike, an out of country bike will probably be a nightmare. Just because the law allows it, is not a guarantee that DMV will see it that way.
