CRG
CRG is a kart chassis manufacturer of recent years, with world champions from 2001-2003. Famous alumni include Alex Zanardi and F3000 racer Vitantonio Liuzzi.
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.
The name change to CRG took place gradually in the early 1990s and ushered in an era of more World Championships from Danilo Rossi and Alessandro Manetti.
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.
They also make the Maxter engine range and the Maranello, Vanspeed, PTK and Zanardi chassis ranges.
