They were founded in the late 1970s by three Italian racers and were originally known as Kali Karts. In the beginning the company was a laughing stock, with Zanardi being told by his original team DAP that if he didn't stop complaining they would "send him to Kali". By the mid 1980s Kali had recovered from its inauspicious beginnings and was winning World Championships with drivers like Mike Wilson.
CRG started to build engines in the mid-1990s but they were never widely used outside of the factory teams. In 2001 they were replaced by the Maxter brand which produces 100cc and 125cc gearbox engines.
