Sorry, been occupied with family & the usual stuff.
I am chasing an Idea, that might let me take you up on your offer, of building me one !
Back in 2006, while visiting friends in Ohio, I bought a used honda CX 500.
Then , since I had no Utility bills etc, I was not able to register or insure the bike, unless I got a waiver from Homeland Security.
I phoned the number the vehicle department gave me, about 8 times a day , for 3 days , and never got an answer.
In the end, the only way we were able to fix it, was , my mate, registered the bike as his, and insured me as designated driver.
I do not know if California is the same.
That was the reason why I bought the Breva in the UK , then flew it over,
Since then, I have, by using different forums, been told, that Montana has ( Or Had ) no restrictions, on vehicle registration etc.
Anyway I am working on a solution. I will get back to you , as & when.
I really like the looks and seat, on the white one, however I would want mine in black.
Also, I hope you are well on the way, to recovery !
Cheers
