In 1970 the BM was the first engine to come to the USA that was not connected to IAME ( Italian American Motor Engineering). Imported by Russell Karting Specialties, the BM was designed and built by Mario Bertuzzi who owned ASTRA Works(Producer of trucks and military vehicles). The BM name came about in keeping with the Italian custom of addressing a person by their last name. Therefore BM stands for Bertuzzi, Mario, in memory of the builder. The BM 100cc/135cc engines went on to win many national and international championships. Some years later, BM was acquired by IAME and became the BM/Atlas line of engines.
