jeste rus al nije ural
Kako nije ural , eto ga pod nepoznatim prototipovima naveden kao model M-75 sa mašinom od M-72 , ali u SV konfiguraciji sa 36 KS i brzinom od 170 km/h.
As seen, the Ural production was basically composed of only two models (750 side valves, and 650 OHV). But the Ural has realized also some prototype, simply derived from the normal versions or totally new. In the first, second and third pics above (taken from an article of the "Motorrad" magazine, by Aleksej Popov), the "M-75" of the 1946 (sidecar and "solo" versions), with the engine of the "M-72", but with new side-valves heads, 36 hp, 170 km/h for the "solo" version. The "M-75" was realized also in a road version (fourth pic), but it never was produced in series. In the fifth pic...no, it isn't a bike crashed on a tree: it's a sidecar for the speed records, with the "M-75" engine and a front single-arm suspension!
