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
- A TSP ERM – See more information here: https://tsp-erm.com/product-features/
- Head O-ring & Washer Kit
- New heat range spark plug (BR9ECMIX)
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
- ERM enables you the ability to make swift pre-set tune changes depending on conditions
- 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
This kit not only gives you the best performance on the market for the best price, but also allows you to make trackside adjustments to fuel, ignition and powervalve using our ERM. This is a MUST for a 125/150SX as they do require adjustment throughout the season for changing track conditions and engine wear. These 125/150 models experience lean symptoms as the engine wears, and this can happen as early as 5 hours. This is due to the the Crankcase pressure sensor trying to make fuelling changes due to the measured piston blow-by, which can make the bike run dangerously lean. In this example, having our TSP ERM you can easily add a few more percent to the fuel table to keep your bike safe as your engine wears.
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.
