X125T Engines are now back in stock - trade in your old engine today!


Currently unhappy with your current engine program?  Feel like you're constantly replacing parts on your engine?  Frustrated with trying to figure out why or what part of your kart's electronics have left you on the grid?  You can trade-in that high maintenance, mediocre engine for an engine that can answer many of these issues.

    X125 went to great lengths to simplify the engine for the racer's benefit.  Karting engines are subject to extreme vibration, and many extra parts on an engine suffer because of it.  What X125 has done is simplify the engine configuration by removing the non-vital parts  without compromising any of the power.  In designing the engine, X125 rethought the competitive kart engine by: 

  • Removing the power box, relay, power valve and ignition switch
  • Removing these external electrical items meant that an elaborate wiring system wasn't needed.
  • Eliminating exhaust leakage by utilizing a one-piece pipe that does not need flex or wrap and is more quiet than the competitors
  • Integrating the water pump
  • Built with an elaborate balancing system to prevent continued service as with most on-engine starters
  • Intra-coil hourmeter for knowing how much time is on engine 

     Essentially X125 "trimmed the fat" off the current configuration of competitive karting engines and introduced a package that is easy to set-up, requires less maintenance and is not prone to on-grid fails.  All while achieving the same power at a lower RPM than our competitor's engines.
