TM quickly gained a reputation for exceptional quality and high performance, and in no time the brand had established itself as a force to be reckoned with. A young rider from Pesaro named Gastone Serafini was chosen to help Battistelli develop the motorcycle and would go on to achieve successful race results. The TM brand gained even more recognition at the 1977 Milan Motorcycle Show, and as a result, manufacturing moved from Flenghi’s small workshop to a new and more well-equipped factory located in the Pesaro industrial zone. During this same period, the Serafini family became part of the TM organization, and by 1978, the factory had produced 200 motocross bikes. In 1979, Tommaso Lolli was hired to work alongside Gastone Serafini to continue development, and in that same year, they built the first TM enduro bikes. In 1982, co-founder Battistelli decided to leave TM, and Gastone Serafini joined Flenghi full-time running the company.
