what is Cass sitting on here?

[Stig / Major Tom]

I can't place the bike.


Cass died in her sleep at the age of 32 in Mayfair, U.K. 1974.
"Left-side heart failure" .....no drugs in her system , nor was a sandwich involved.

That young lady could sing!

The engine looks like it could be a Triumph Stig, but the running gear isn't.  Maybe a hybrid with a Triumph lump shoehorned into an featherbed frame?...  (A Triton?)

Well I beg your pardon!  Who knew?  Thanks for adding to the sum of my knowledge!  Still wonder where the Norton engraved badge has gone from the crank case in Stig's pic though!

That seat and tank was called the "fastback".    https://www.classicdriver.com/en/article/motorr%C3%A4der/norton-commando-750-fastback-command-and-conquer   Here's the same model in red with a nice friendly rider.

Well yeah - OK - but I like the green one with the gold Norton script!

Me too Stig.  Always had a yearning for a Commando and an AJS350 single. Closest I’ve got is a 320 Kymco single 😂🤣
