The FLAWLESS ECU Performance Flash for the Aprilia RS 660 optimizes the software of the original engine control unit – for model years 2020 and later. The result: more power and torque, cleaner throttle response, and less constant-speed surging. Every software optimization or flash for your Aprilia RS 660 is individually tailored to your vehicle and your configuration – no off-the-shelf maps. Developed in-house and Made in Germany.
