This package suits all KTM ‘GROUP’ 125 2023-on models with the new 125 TBI (Throttle body injection) engine. (Gasgas & Husqvarna Models)


This package includes:

  • A Billet TSP Head (Cap and Insert)
  • Thicker base gasket to suit TSP’s combustion design
  • Reflash of your stock ECU with refined Power valve settings, improved fuel and ignition maps developed by TSP.
  • Head O-ring & Washer Kit

This package makes a huge difference to the 125TBI 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 fuelling
  • 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.
