Bet you've never heard of this one!

Vostok S-565

The Vostock was a 4 cylinder 500cc Grand Prix racer built in the Soviet Union.

The engine was a very MV like DOHC four with 3 valves per cylinder (1 inlet, 2 exhaust), and it produced around 80 bhp.

It competed in a number of GPs in 1968 and 69, with its best result being a 4th. Then it was withdrawn and never seen again.
