Owning a US Motorcycle as a tourist?

[scrubs]

I am from the UK and plan on spending approx 2 months travelling the US by motorcycle.
I figured if would be more cost effective to purchase a bike (old one)
instead on renting and sell on when I leave. When speaking to a friend
earlier today he told me to check whether it would be possible, because
as far as he understood with regards to 'cars' at least - is that is not possible for a non
US resident to own a vehicle..


In real world terms where does this leave me? will I be refused insurance?
I'm assuming I need a address of residence or something, can I just not use
a hotel address or is there any simple work a rounds without border runs and
excessive hassle?

Kinda bummed by the whole thought as I was really looking forward to it
and did not even consider it being a problem.
