Album of history of Irbit models

Introduction: This is a digital reproduction of a very special and very rare handmade and handbound hardcover book, typed on an old Cyrillic language typewriter with the small gloss black and white photographs glued on to the pages, the titles are done with some kind of letraset and the label below stuck to the front cover. The album covers 21 different models of motorcycles and sidecars produced at IMZ from 1942 to 1970 (which was only the beginning). The pages and photos are ageing so it is very fortunate to have been possible to make scans of this little gem from IMZ-Ural

Special thanks to Steve Wiggins for providing this very special book to make a digital scan specially for us here at b-Cozz.

Special thanks to Eugene Radchenko, Russia for translating it specially for us here at b-Cozz site.

Further notes:

“S”, (or “C” in Russian), was generally to mean an association with Serpuhkov Institute (S-51), it also stands for “Sport” (спорт) (M-52S, M-53S)

Ural-2 was Model M-63, Ural-3 was Model M-66

* Earliest M-72 had single clutch plate, during war some engines were made of cast iron due to shortage of aluminium (aluminum)

** sidecar torsion bar was replaced with swinging arm and suspension introduced during M-63 (Ural-2)

Translator’s note:

I translated this with pleasure and interest of my own. The book is titled “Album of history of motorcycle models of Irbit plant”. Think it was meant for in-plant staff use or for narrow circles given it was printed on a typewriter, which was typical for USSR till “new age” with Boris Yeltsin reign. “Glavmotoveloprom” (to understand): “Main Motorcycle and Bicycle Industries”, blending of words in Russian, typical for Soviet times as Lenin introduced this “fashion”. – Eugene R
