Wow! What a coinkadink! Today I bought a 2011 Downtown 300i that is registered in Montana...and I'm in California, too. I immediately went to the Auto Club and the clerk said all I will need to do is get the VIN and engine numbers verified (by the Club) and there are no smog requirements because it's a motorcycle (well, duh). He didn't mention fuel tank vapor capture requirements. I assume that's what you are concerned about and now I am, too. It never crossed my mind.
