For one year only BSA made a super sports
650 pre-unit twin called the Super Flash.
It was conceived specifically for the
US market and most of the 700 machines made went there. Little
information was published about them in their short life and they are
rarely mentioned in books about BSA history. Few have survived.
This web site is a
collection of 'stuff' that I've found in my own research that may be of use
to other 'Super Flashers'. Some of the images are very big but I'm guessing
you will want detail if you can get it. It comes from a variety of
sources and people who couldn't remember where they found it. I've made some
attempts to get permission where copyright might apply but if I missed
you I hope you'll have sympathy for my intention to serve the greater good. If
I get something wrong I expect you to tell me and I'll be happy to stand
corrected.
This is the not
the definitive history but it's the only resource you'll find on the web!
