Here is proof that it really is all about the engine more so than it is the trike. Here a rider on a Catrike Trail races others including other trikes known to be “fast trikes”. He doesn’t win, but he places second beating all but one of those “fast trikes”. He loses to a Catrike 700, but he beat an ICE VTX (or Vortex ?) and a Catrike Speed. I am impressed watching this video.
