The Rapid Bike EVO ECU 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 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 for closed-course competition use only.

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.

I recommend the Rapid Bike EVO auto tuner to all of my riding buddies. It couldnt be easier. Once you install one of these, you will never look at power commanders and other units again.

No laptop needed, no downloads, no expensive dyno tuning. Most of the bikes I have installed this on require removing the gas tank and airbox, so you can get to the injector plugs. Aside from that, the install process is just finding the right connectors on the bike, and simply plug and play. It seems that removing the gas tank and air box is the hardest part of the install. I must admit, seeing the Rapid Bike wiring harness makes most people panic, but with the photo instructions, its really not that bad.

I have found that right off the bat, the bike runs smoother and has better power delivery. After about 100-150 miles of riding, the tune is literally perfect. The unit just keeps tuning the bike based on air temp, elevation, even new mods. This is a must have.


Every time someone asks about installing an exhaust, the first thing I ask them is...."what are you doing for a tuner".  It seems that bike manufacturers are having to play so many games to comply with emissions, that stock bikes even come with bad air/fuel tunes. Some Ducati models actually run terrible at low RPMs right from the factory.  Even without an exhaust, I would recommend installing a Rapid Bike to a bike. Plug it in and ride. That's the best part. Rapid Bike has amazing technical support, which is important to me when a customer has a specific question or issue, I know I can get them taken care of.
