Build your own CycleKarts. They are small, lightweight, nimble machines made by their drivers for the pursuit of simple fun motoring sport. They're not serious speed-machines or status-generating show cars. They're purely for the gritty fun and satisfaction of tearing around in a machine you've built yourself.
Drivers have to make their own cars, as we decided some time ago that no one should be able to just fork over money and buy a CycleKart. Proper appreciation for the sport and the machines requires one construct one's own car.
