Creating an affordable tourist model was first task of a new division in PZInż construction office. The motorcycle division, established in 1932, was led by Tadeusz Rudawski. His team consisted of engineers: Zbigniew Możdżeński, Tadeusz Marek, Jan Bidziński and Jan Kleber, and technicians: Stefan Poraziński, Stanisław Kostrzewski, Jan Gebler, Raczek, Jakubiak and Pola Łukawska. Rudawski was a talented engineer and sports rider, too. His brain-child, CWS 600 RT (R for Rudawski, T for Tourist) was designed both for military and civilian use. Mass production started in 1936. The new model was named Sokół ("falcon") and it's known as Sokół 600 now. The frame and suspension were similar to British Ariel, but the engine was Rudawski original design. It was the best motorcycle built by PZInż, both reliable and easy to ride, and its price was acceptable for individual clients. In 1937 the basic price of Sokół 600 was 2300 zloty, with a sidecar - 2980 zloty. In 1935 Rudawski team worked also on sports version, RT 500 (R for Rudawski, S for sports) and a little earlier Możdżeński worked on his own design, MS (M for Możdżeński, S for sports) but none of these models were mass produced. RT 600 was produced till September 1939; over 4000 units were built. Sokół 1000 was also continued in this time. Both models were used by Polish army during September campaign in 1939.
