What's New in Jetting for KTM 2T Dirt Bikes

2.1

August 25, 2026

New in this version: a mix calculator, and a new icon. • Mix calculator. It tells you how much oil to add to the petrol you are about to mix, and also the other way round: how much petrol the oil left in the bottle will take, or what ratio you actually ended up with. Litres, millilitres, US and imperial gallons and ounces, with petrol and oil in different units if that suits you. One button takes the resulting ratio to the Engine screen. It sits right below the oil ratio, which is where you need it. • New icon. The bike cut out in white on orange, like the rest of the family. The old one was a photograph, and at icon size you could not make anything out. • The ratio row is now called "Oil to petrol". The percentage is oil against petrol, not against the finished mix, and the row title is the place to answer that question. • The calculator has its own help screen, all of it translated into the app's seven languages. And what arrived in version 2.0, in case you missed it: • Logbook. Save any calculation and write down afterwards what you actually fitted and how it ran. Rate the low, mid and high circuits separately, note the place, and export everything as CSV or share a copy to move it to another phone. • The GPS tab is gone. Asking the nearest weather station for temperature, pressure and humidity now happens inside Conditions, which is where those values are used. No more going back and forth. • Seven new model/year combinations: 125 XC-W, 150 XC-W, 250 XC-W and 300 XC-W for 2017, the 125 XC for 2021 and 2022, and the 65 SX for 2009. • The weather station request no longer blocks the interface, and station names are no longer truncated. • Fixed: on the Results screen the Help, + and ... buttons sat on top of the first boxes. The layout now works itself out from the safe area, so it keeps working on any screen. • New launch screen with the app logo. The old one was a screenshot of the app with made-up figures, and it no longer looked like the current interface. • All the help texts rewritten screen by screen: they still described a GPS tab that no longer exists. • Fixed: the "more apps" screen showed titles without icons.

I really like this app

This app has boosted my bike's performance, now it runs cleaner and faster

Good tool to make your bike run clean and fast

Before using this app my SX125 was running too rich with stock jetting, that caused a poor performance and excessive oil leaking from exhaust. With the recommendation of this app now it is running much better, having more mileage and with much less oil leaking. Definitely this app is a must to make your bike run perfectly.

Good app to make life easier

Happy with the results. Recommended app.

TC125

The information from the GPS weather always says the same thing for altitude 164 feet. We are at 3600 feet above sea level. I also the the KTM app and it work fine. I wish it could be reset or something.

This application calculates the optimal jetting configuration for KTM 2-stroke MX and enduro dirt bikes. It considers environmental factors like temperature, altitude, humidity, and atmospheric pressure, along with your engine's specific details and oil mix ratio, to provide precise recommendations for your main jet, needle, pilot jet, and air screw.

How does the app get weather data?

The app can automatically retrieve current weather conditions by using your device's location services (GPS or WiFi) to find your position and altitude, and then connecting to the internet to fetch data from the nearest weather station. Alternatively, you can manually input all weather-related values if you do not wish to use location services or an internet connection.

Can I adjust the recommendations?

Yes, the app allows for fine-tuning adjustments to adapt the recommended jetting configuration to your specific engine's unique characteristics. This ensures you can achieve the best possible performance tailored to your bike.

Is this app compatible with fuel-injected bikes?

No, this application is exclusively designed for KTM 2-stroke engines that utilize a carburetor. It is not valid for fuel-injected engines.
