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

2.2

October 10, 2026

Version 2.2 FUEL • New: choose your fuel — pump petrol, E10, E15, ethanol-free, race or motocross — and the jetting is corrected with its stoichiometric ratio and density. CARBURETTOR ICING • New: an icing warning from the temperature and humidity. On enduro bikes (EXC, XC-W and MXC) it also warns at higher temperatures. TRACK MODE AND TRACK DAY • Your jetting full screen, large and high contrast, to read it in full sun with your helmet on. • A 12-hour track day: the main jet on the lock screen, in the Dynamic Island and on the Apple Watch. • The app follows the phone's dark mode. WIDGETS AND APPLE WATCH • Home and lock screen widgets and an Apple Watch app with complications. ALERTS • If the weather changes enough to change the main jet, it tells you. ICLOUD AND SHARING • The logbook and settings sync through iCloud between your devices. • Share your jetting with your mechanic as a link, a file or a QR code. AND ALSO • Location now works on iPads without GPS and indoors. • Report a problem from Results and from Help. • The distance to the station no longer shows as "0.0 km", and "More apps" looks better. IN PREVIOUS VERSIONS • 2.1: a fuel and oil mix calculator, and a new icon. • 2.0: a ride logbook, the weather station inside Conditions, a new launch screen, rewritten help and seven new model and year combinations.

Good app with practical application, would be great to have access to technical support team for fine tuning.

I really like this app

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

Response from developer

Sorry for taking so long to reply, and thank you. Version 2.1, released in August 2026, adds a mix calculator that tells you how much oil to add to your fuel, and version 2.0 brought a ride logbook and the weather station lookup inside the Conditions screen. We have changed how we handle reviews and emails, and from now on all of them get an answer.

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.

Sorry for the late reply, and thank you for the detailed account of your SX 125. Since version 2.0 (August 2026) you can save each calculation in a logbook and note what you fitted and how it went, and version 2.1 adds a mix calculator. We have changed the way we look after reviews and emails, so every one now gets a reply.

Good app to make life easier

Happy with the results. Recommended app.

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.

Response from developer

Hello, the update should fix your problem. Please test it again and send us an email to mobile@isenet.es if it's not working yet. Best regards.

What does this app do?

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.
