Poland's "M-14 Iskra" of 1962.

Via: autosoviet

"Poland's Junak factory (a maker of single-cylinder bikes inspired to British realizations) realized a very interesting prototype: the "M-14 Iskra" of the 1962 with a totally new parallel-twin (350 cc, SOHC, 24 hp, 140 km/h), and with a very advanced fairing, realized in fiberglass and similar to the English Ariel "Leader" motorcycle. After this realization, the Junak brand disappeared definitively in the 1965.

However, recently it's reappeared with a new cruiser model, the Junak "Millenium 250" twin (sixth pic)...but this bike is simply a Korean Hyosung, produced under Suzuki's license. There is nothing of Polish on this motorcycle."
