TM History

Founded in 1977 by two friends with one common great passion…speed, the philosophy that distinguishes the MOTO TM engine is the choice of quality materials, assembled with care and leading to great performance.

Childhood friends, Claudio Flenghi and Francesco Battistelli (Mr. Motor and Mr.Chassis), spent a great deal of their life working with motors, which eventually lead them into the world of karting. Since it’s inception, MOTO TM has fueled the rise of many national and international drivers. MOTO TM has dominated the last ten years of karting in the 125cc category by winning the World Championship each year. TM is the only manufactures to produce 100cc engines as well as Moto Crosss bikes in the industry. MOTO TM is currently located in the industrial zone of Pesaro, Italy.
