2-stroke expert Dr. Joseph Ehrlich set up EMC in the late 1940s. The company produced a handful of street bikes, and was quite successful in racing up to the 1960s. EMC made a brief comeback in the early 90s, financed by Quadrant Shocks. In 1993, they commissioned this design from me for a 250cc 2-stroke GP bike, although I've no idea what became of it.
