Cyborg is a monster truck currently racing in the USHRA Monster Jam series. It is owned and driven by Jack Koberna. It is notable in that it is the only two-wheeled drive vehicle on the circuit, and features an independent front suspension, as the front wheels are the two which are not powered.[citation needed] Although this provides recognition, the two-wheel drive presents a serious competitive disadvantage, as the truck cannot climb over obstacles as easily as other trucks.[citation needed] However, the front suspension has received large amounts of attention from other teams. Although Jack runs Cyborg most of the time, he does have a four-wheeled drive monster truck that is called Tuff-E-Nuff that runs on occasion.[citation needed]
