The kart is a simple vehicle, with essential elements, but it can be enhanced by many accessories, even less known ones, which are often very useful. Like at the steering wheel, where, for example, a fuel return valve allows the carburation of KZ karts to be varied on the track; as well as in the delicate transportation phases, when essential objects such as the caps for the protection of the carburetor inlets can prove to be essential. Here are some suggestions, at low cost, for smart accessories, easily purchased in any specialised shop, even online.
