Genau das war auch mein Gedanke, dass man den Kolben durch das Kerzenloch einbauen könnte!
Über die Suchanfrage hat Herr Gockel mich zu den 50 cc Suzuki 2- bzw. 3 Zylindern geführt.
Wegen der Farbe des Rahmens dachte ich, es sei eine Suzuki...
...Tatsächlich ist es wohl eine Mitchel 50/4 von 1959, die bei Sammy Miller steht!
So, ich hoffe, dass das so für Dich in Ordnung geht:
"1959: MITCHELL 50/4: Note the date, 1959, even more importantly the country of both design and manufacture, England! The only four cylinder 50cc two stroke motorcycle racer in the world with jewel like individual cylinder displacement of nominally 12cc. Each cylinder has a bore of 25.3mm and a stroke of 25mm with a compression ratio of 10.1, maximum power was 5bhp @7,000 rpm driving through a five speed gearbox. The engine is suspended from a diamond frame arrangement, canted into the airstream with downdraft carburetion, staggeringly with one Amal 10mm carburettor per cylinder. The suspension is leading link type at the front, incredibly it utilizes a rubber link as the damping medium and conventional dampers are at the rear. Note the petrol tank with substantial scalloping for the riders knees, it is a work of art!
The motorcycle was designed by Eric Fity-Hugh and manufactured by Duncan Mitchell of Stevenage, UK. The motorcycle was never raced due to financial problems."
