Honestly, gas karts suck. Outside being covered in fumes and getting a migraine, they do not have nearly the same acceleration or consistency of our electric karts. Most gas karts for adults run a 270cc Honda that produces about 9hp. Our 11KW electric motors are the equivalent of 14.75hp and deliver their power INSTANTLY rather than waiting for the right RPM. Our karts are also belt driven making them quieter allowing you to focus on what your tires are saying rather than the engine.
