TSP ERM Power Kit all KTM Group 150SX TBI models

This package suits all KTM ‘GROUP’ 150 2023-on models with the new 150 SX TBI (Throttle body injection) engine. It also suits KTM Group 125SX models from 23-on with the genuine KTM150SX top end fitted.

Models include:

• 2023-on KTM 150 SX/XC TBI
• 2023-on Husqvarna 150 TC TBI
• 2023-on GasGas 150 MC TBI

Please note – it does not suit the 150 enduro models such as the KTM150EXC or Husky TE150. We have a separate product listing for the enduro 150 TBI bikes.

This package includes:

• A Billet TSP Head (Cap and Insert)
• A TSP ERM 
• Head O-ring & Washer Kit

This package makes a huge difference to the 150SX TBI over stock, with some key features being:

• Improved performance through the whole RPM range
• Over 42hp up top with more overrev and super strong bottom/mid.
• Significant mid-top RPM performance with more over-rev
• The ERM allows you to make swift pre-set tune changes to suit local 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
• The ERM also features a range of service functions to help keep your engine in top condition iron all season

This package works extremely well with the DOMA or Oxa exhaust system.

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 run-time for top level riders. This is due to the the Crankcase pressure sensor trying to make fuelling changes due to incorrect measurements from engine 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.
