>>Not to cause further confusion, but there was a well known British bike named Enfield.
Royal Enfields are still made in India too. They still have the Royal Enfield Bullet model (to add to the confusion). Same exact design and tooling as I understand it.

Wow! Now that really is surprising.
It's been years, but I've seen 650s that had Enfield and others that had Royal Enfield on the tank. I wasn't sure whether the company had changed names at some point, or the 'Royal' was their top of the line model. I always wondered if they were made by BSA, since it stood for British Small Arms.
