Cobra and an Egli-Vincent. Examples of the top road burners, of the 1960's, on 2 and 4 wheels. Both "hybrids", one a US motor in an English chassis, the other a Swiss designed chassis for a British motor. Interestingly, both have unusual speedos. Smiths made a special 5" motorcycle speedo that was only supplied to the Vincent factory, with a dial that went up to 150 MPH instead of the normal 120 MPH 3" speedos fitted to just about every other British bike.
