History edit
In 1933, mining engineer Gustaw Różycki bought a small mining machinery factory in Załęże, Katowice from Alfred Wagner and renamed it Fabryka Maszyn Oraz Odlewnia Żelaza i Metali MOJ.[3] He set about expanding the company and by the time WWII broke out the number of employees had risen from 15 to 800.[4] The company produced mining equipment, boat engines, chain saws and other machinery.[3]
Różycki was a motorcycle enthusiast and wanted to produce his own machines. In 1935 he employed engineer Karol Zuber to head a new motorcycle division.[3][5] The first motorcycle, the MOJ 130, was produced later that year. It had a 128 cc two-stroke engine. A 250 cc machine was in development,[3] and there were plans to produce cars. Land had been brought in Sandomierz to build a second factory for car production. Car production was due to start in 1940/1 but the war brought an end to this plan.[5] A rotary engine was in development and Różycki was granted a patent for the design.[5][2]
Following the German invasion of Poland, the factory was commandeered by the Germans to produce mining equipment and ammunition, although a small number of motorcycles were manufactured for military use.[3] Różycki joined the resistance and as a result spent the rest of the war in concentration camps in Dachau and Gusen.[3]
After the end of WWII, the factory was nationalised[5] and it was decided not to re-establish motorcycle production.[3]
Models edit
MOJ 130 edit
The motorcycle was modelled on German motorcycles of the time, with an emphasis on quality.[3] Prototype models were fitted with a Villiers engine, but production models used their own 128 cc single cylinder two-stroke engine. A rigid duplex frame was used with pressed steel girder forks. Most components were made by the factory or were from Polish manufacturers.[6] The motorcycle was presented to the press in February[5] 1937[4] and production machines were available in August of that year.[1]
In 1938 the engine was improved with dual exhausts exiting the cylinder at the rear and the carburettor moved to the side of the engine.[1] The gearchange was changed from hand to foot operated.[7] Some machines were purchased by the military, including the 10th Motorized Cavalry Brigade. There was also a state-funded purchase scheme for officers to buy the motorcycle.[6]
A few competition versions of the model were made and on which Różycki entered various events, including the 1939 Tatra Rally, which he won.[4]
Around 600 units of the MOJ 130 were produced pre-war.[1][4]
