When I left N-V in June 1968 to emigrate to Boeing, I could've bought a '69 Commando for the employee discount price and Boeing would have paid to ship it.
I think the going employee price at the time was about 375 UK pounds, which would've been around $1000.
I've often wondered whether I'd be dead by now if I'd brought one over. After settling in Seattle, I concluded fairly quickly that the environment for bikers back then was extremely hazardous. There was a quote on TV not long after we arrived from the head of the State Patrol who said that "there are two kinds of motor cycle riders - those who have had a bad accident and those who soon will."
My main concern was that the US drive on the opposite side of the street. When you're in a car, you have a built-in reminder because you're sitting on the other side. On a bike, no such stimulus. I did a bit of off-road riding in the first few years, but packed that in due to family commitments.
Now that I've retired a second time (from being a transit coach driver) I might consider a Honda Helix for in-town use, but I don't think there are any high-performance biks in my future. I don't like being dependent on one vehicle, so if I come across an AJS Stormer in someone's barn, I might be tempted.
