Hi Guys :-)
I thought you might be interested in a Jota based machine I designed and built in the UK in the 1980's while running a small business called Saunders Motorcycle Engineering (UK).
The frame was fabricated from T45 aircraft tubing, while the swing arm was fabricated from T45 and Reynolds 531 tubing. It was finished in stove enamelled Candy Red. The Fuel tank was handmade in aluminium.
The bike looks better with the solo seat attachment on :-). It is off in this picture.
