2023 KTM sx 125 Electronic fuel injection

The 2023 model , the first KTM 125 using fuel injection has arrived. The Efi system has been on other size engines for years and works quite well. Inside the engine has not changed very much at all. On the Dyno, compared to  the older carby version  2022 ,  the 2023 doesnt rev as hard, so basically the midrange power has increased a small amount, but the top end power has been reduced, as well as the top end revs.   A better exhaust chamber, better cylinder head and a better ignition map  will give   good power  gains, as well as modified fueling maps.  Cleaning the intake and calibration of the powervalve and throttle position sensor is required.    The 2024 and 2025 will only get better.
