Royal Enfield?
No, Triumph Trident (vintage 1969). Only bike I ever owned, bought it in 1972. Took it for a test run, saw that it was a great go-faster and I had to have it.
You can buy a nice used 250cc Enfield in Nepal or India for about $300 to $500. What's really great is that you can get parts and service anywhere, since they're indigenous Indian bikes and (I think) still in production.
Someone was importing them to the U.S. a few years ago.
