Friday bike

1984 Jawa Typ 824 500cc prototype

Found a few pictures of this on the Web. In 1984, Jawa showed a prototype of a 500cc OHC flat twin. Very little information on it other than only 10 were built, but it didn't reach the production stage.

You can see from this drawing that it had a fairly convertional engine layout with cam chains running up the rear of the cylinders, and vertical inlet and exhaust ports.
Power output was claimed to be 27 kW (36 bhp) and dry weight was 176 kg (388 lb).
Probably the only video of one running:
