The FLAWLESS ECU Performance Flash for the KTM RC optimizes the software of the original engine control unit – for the KTM RC 125 and the KTM RC 390. The result: more power and torque, cleaner throttle response, and less snatchiness at constant speeds. Every software optimization or flash for your KTM RC is individually adapted to your vehicle and your configuration – no off-the-shelf maps. Developed in-house and made in Germany.
Why are there two versions per model based on the year of manufacture?
KTM switched to a different engine control unit for the RC 125 and RC 390 with the 2017 model year. Therefore, there is a specially developed optimization for the years before and after this change.
