1960 AJS 31CSR 650cc at Andy Tiernans  

Nice old bike in excellent condition, sounds lovely too.

Excellent machine with a famous name, suitable for very long stretches with good heat dissipation, in addition to being beautiful. With high compression pistons a marvel. Thanks again for this video.

That's a gorgeous bike you could go for a swim in that chrome.

My brother had a new one in the early 60's, it was known as the sports twin as well wonderful bikes≥

Nice bike think the CSR looks good with them mudguards and the twin downtube frame , later ones matured into really good bike with the road holder forks / big Norton front brake . Nearly got a 67 one till someone beat me to it , always thought they were better engine than Triumph/ BSA with having a center main

A proper motorbike.

aside from the badge, ir's a matchless. or contrariwise.

Andy, Did you used to be in the states? I think I spoke with you years ago.
