This TSP TBI ERM Power Kit fits 2023+ KTM, Husky and Gas Gas 125 models with the new 125 TBI (Throttle body injection) engine.

This package includes:

  • A handheld touchscreen ERM device which comes with a free downloadable TSP ECU Tune to suit your bike & relevant TSP modifications. For a full breakdown of this product, check out the TSP ERM website.
  • A Billet TSP Head (Cap and Insert)
  • Thicker base gasket to suit TSP’s combustion design
  • Head O-ring & Washer Kit
  • A new NGK BPR9EIX spark plug, better suited to the improved power the engine makes with this kit

This package makes a huge difference to the 125 TBI over stock, with some key features being:

  • Significant mid-top RPM performance with more over-rev
  • Drastically improved throttle performance in the whole RPM range
  • Both Green & White maps are tuned and the stock map switch works like normal to select between the customised maps.
  • Smoother throttle response
  • Better fueling
  • An extra 2HP+ at peak power
  • Much more enjoyable to ride

It features an improved combustion chamber design that gives more performance from bottom to top as well as reduced risk of detonation.

All TSP mods are designed and dyno tested in-house at TSP so you can be sure you’re getting reliable performance for local conditions.
