The first time that we heard something of the GM engine was back in 1979, when, in an Italian motorcycle magazine we found an article of a brand new speedway engine made by Giuseppe Marzotto. As long ago as 1964, Marzotto started out with Moto-X racing and for some 10 years, he was to race on many different machines such as Greeves, Maico and Husqvarna. But Moto X racing plus hard work on the farm of his parents was simply too much.
