Sharp-eyed observers will notice that this is an Ariel not a BSA. However the former was part of the BSA group and shared many components, including the A10 engine in the case of the 650 models. The last year of Ariel fourstroke production (58) saw the high perf Road Rocket spec Cyclone model produced for North America... as notably owned by Buddy Holly.

My dad put this one together a couple years ago and it actually has the Rocket's alloy head as well...while all the Ariel timing, rocker box covers, etc still fit!

It goes good! Rave on.
