TSP TBI 12 Degree ERM Power Kit
This is THE package you need if you are even half serious about racing a 125 TBI!! This kit not only gives you the best performance on the market for the best price, but also allows you to make track-side adjustments to fuel, ignition and power valve using our ERM. This is a MUST for a 125 TBI as they do require adjustment throughout the season for changing track conditions.
The TSP TBI 12 Degree ERM Power Kit is designed for KTM, Husky and Gas Gas 125 2023-on models with the new TBI (Throttle body injection) engine.
This package includes:
- A Billet TSP Head (Cap and Insert)
- A TSP ERM with TSP ERM Rain & Dust Cover
- Top End Rebuild Kit with 12 degree piston
- A new NGK BR9EIX spark plug, better suited to the improved power the engine makes with this kit
Please note – This Must be used with a 12 degree piston. Select “A” or “B” piston size to complete your order.
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
- More power everywhere over our non-12 degree head design
- Drastically improved throttle response and performance throughout the whole RPM range
- The ERM enables you the ability to make swift preset tune changes depending on conditions
- Both Green & White maps are tuned and the stock map switch works like normal to select between the customized maps.
- Smoother throttle response
- Better fueling
- An extra ~5HP+ at peak power
- Much more enjoyable to ride
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.
