Bolesław Proch (4 February 1952 – 22 December 2012[1]) was a Polish international motorcycle speedway rider. He earned 15 international caps for the Poland national speedway team.[2]
Born in Świebodzin, Proch first rode for Falubaz in his home town of Zielona Góra in 1973, winning the Polish Junior Championship the following year and finishing fourth in the Silver Helmet tournament.[3] In 1976 he rode in the British League for Reading Racers, averaging over five points per match. In 1977, in mid-season, Reading were ordered to weaken their team as it was found to be exceeding the points limit set by the BSPA which resulted in Proch moving to Leicester Lions in a deal that saw Doug Underwood moving to Reading.[4]
He returned to Poland where he rode for Stal Gorzów Wielkopolski (1977–1980) and Polonia Bydgoszcz (1981–1987).
