Chris,

My old man has imported a 71 Vette before, Import duties are a killer. Esp if the scooter is sold here which it is. You will pay duties up to the value of one for sale here so you wont save anything, plus you need to remember freight etc..

My cousin is in the industry in The bay area in SF if you do want some help, he could definitely do a lot from his end but you will not save any money that is for sure. As for registering a bike I am sure you would be fine esp from a place like CA which has mega emissions policies etc..

PM me if you want some help and I will see what I can do for you.

Dan
