The Rapid Bike EVO ECU Piggyback Tuning Module includes the Rapid Bike EVO module, USB cable and model specific wiring harness.

The Rapid Bike EVO kit is the perfect tuning solution when you add an exhaust and/or air filter to your motorcycle. This allows you to easily get the best performance and reliability out of your bike.


Rapid Bike EVO is a completely automatic tuning solution. The piggyback unit installs with all plug-n-play stock connectors. Once the unit is installed, the Auto-Adaptive feature monitors your air/fuel parameters and applies the necessary adjustments AS YOU RIDE. No need to connect to your computer, mess with software, or make any changes. JUST RIDE. The Rapid Bike unit handles all the tuning. Perfect for stock bikes, slipon exhausts, full systems, and other common motorcycle upgrades.

Because this unit simply piggybacks the ECU, the unit can be removed at any time, and does not make any permanent changes that may affect the factory warranty.


RAPID BIKE EVO module manages up to 8 injectors and modulates the signal up to two O2 sensors (up to 2 lambdas). The purpose of the O2 sensor (lambda) modulation is to prevent the stock ECU from recognizing the adjustment applied by the RapidBike module to the injection map without any further attempts to re-set the stock parameters matching the criteria fixed by the restrictive exhaust gas emission laws. 

The Rapid Bike Evo module’s most important benefit is the Auto-adaptive feature. This offers the ability to automatically correct the injection map by reading the signal of the stock O2 sensor (lambda) and making the adjustments automatically while riding the bike.

When riding the motorcycle, the self-adaptive feature determines the automatic self-correction of the air/fuel ratio maps: this active management is added up to the pre-set parameters. The adjustments set by RapidBike EVO improve the engine efficiency in order to reach the best performance.The self-correction process is set in multipoint technology according to RPM and TPS, for the whole range of the engine working, even when the original RPM limiter is raised (when available).
Modulating the stock O2 sensor (lambda) signal is a technology far more advanced than the so called “O2 sensor eliminator” (or any other similar device used by the competitors) since they send a static/constant signal which is in conflict with the typical behavior of the lambda sensors, therefore causing the main ECU to perceive such a constant signal as a mistake to be corrected.
The Rapid Bike Evo module is can be moved to your next bike and simply sent back to Rapid Bike for a map reflash (assuming the a tune is offered for that bike). All you would need is the proper wiring harness (available from Rapid Bike). This essentially means this could be the last tuning module you ever buy!

On most models, the Rapid Bike Evo unit can remove the speed limiter and to increase the rpm limiter up to 1000 rpm over stock rev range and also has an accelerator pump feature.

QUICK SHIFT READY: Rapid Bike Race and Rapid Bike Evo systems are quick shift ready. All you need is the additional Rapid Bike quick shift sensor.

Note: All Rapid Bike products are designed for closed-course competition use.

Note: The optional "My Tuning" Bike Module is highly recommended if you want to add the "Map per Gear" function. The "My Tuning" module is not required for the Rapid Bike system to run it's internal auto adaptive tuning feature, but it will increase the speed and accuracy of the adaptive tuning to be a real time tuning solution. Suggested for track use that may have varying parameters (race fuel vs pump gas, morning practice sessions vs warmer afternoon sessions, etc)

    Do I have to download any maps for this?

    Feb 28, 2019, 03:58:21 PM

    No, the beauty of a dynamic auto tuner, is that you can say goodbye to static maps. The rapid bike unit develops its own base line, and then automatically makes progressive adjustments based on your bikes parameters, air temp, conditions, etc. Truly an amazing unit.

    How hard are these to install?

    Feb 28, 2019, 04:01:52 PM

    The instructions included are very useful, and Rapid Bike maintains a USA based office that is available for phone or email support. We have installed 30+ of these units here at the shop for our personal builds, and can say, these units are easier to install than most. The Rapid Bike unit uses the same factory wiring connectors that your stock bike uses. This means the unit is completely plug and play. The most difficult part of install, is typically the removal of some stock bodywork components that allow access to the plugs you need to access.

  • I got this tuner with my Arrow exhaust. I installed both at the same time, so I dont know which one did the most, but all I can say is that my Z900 is a whole new animal now. The bike pulls so hard. Im very happy that motovation suggested this tuner for me.
  • Easy to install, No Dyno necessary and great tuning results!
  • Makes a big difference when added with a SC-Project exhaust
