I'm just a little intrigued by that Velo, is it really a 500cc ?
The head is a postwar MAC alloy head, Macs are 350cc (68mm bore from memory) so maybe they've used an MSS or Venom bottom (500cc) end and cylinder and machined the MAC head to suit, (which could allow them to include a decent bit of squish). I haven't (yet) heard of that being done using a MAC head, though it's not uncommon to stick a machined Viper (350) head on a 500 Venom to get a punchy squish band.

This beauty must surely qualify as a 4 Stroke Classic.

We may yet need to do a little work on improving the ground clearance though!

Just quietly mate you might need some wider bars too, but I like how you can use the header pipes as side stand...

Going back to the Velocette questions a few comments back, I don't know the spec of that bike but believe it belongs to Paul Jackson in the UK.
If you need to know more I guess he could be contacted via the Trials Central website.

A Rigid Velocette Trial I competed against in Cornwall, about 20 years ago.
Only remember his name a Chris.
