Rapid Bike EASY is an O2 sensor modulator. By altering the AFR values, it gets the ECU to modify the injection values. As a result, it improves the throttle response and eliminates the torque and power surges typical of the low and medium ranges.
In other words, it is an effective solutions to get rid of those annoying flat-spots that are common on Euro4 (and soon Euro5) bikes.

Simply PLUG and PLAY!

The installation is quick and intuitive.
Rapid Bike EASY will plug on the stock O2 sensor connector(s) and the negative pole of the battery. The next step is 
a very simple procedure: Thanks to the two trimmers, it is possible to configurate the unit for each different bike and subsequently for desired fueling modification. For this reason, model-specific settings are recommended in the instructions.

EASY add-on module can manage up to two O2 sensors and suits every bike or scooter in standard or lightly modified configuration.

Touring and Cruiser bikes are the ideal candidate for RAPID BIKE EASY

Our entry level unit is not meant to deliver the maximum amount of power, but to deliver the best possible riding experience. Being mainly effective in the so-called "closed loop", Rapid Bike Easy will smoothen the power delivery and throttle response up to 6000 revs, at partialized throttle. As a result, it will improve your riding quality in daily commute and travels. To sum up, it represents the best value for a tune that you can enjoy everyday.


We recommend Rapid Bike EASY to the rider who wants better performance and throttle response while looking at the value-for-money of the modification. It will be effective especially up to 5/6000 RPM. As a result it is the ideal solution for traveling, commuting or urban riding. Among its best applications, we find brands such as: Aprilia, BMW, Kawsaki, KTM, Moto Guzzi, and many others.

As an O2 sensor modulator, Rapid Bike Easy works on the signals showing the AFR to the ECU; consequently, it will get ratio richer or leaner, without side effects on the idle or wide open throttle.

Rapid Bike Easy Settings

Thanks to the trims on the main module you can decide how much fuel to add or remove from the injection. The "Setting" trim value depends on the model, therefore we indicate the correct one in the instructions. As for the "Fuel Ratio", we recommend an optimal value for each model. Nonetheless you can go richer or leaner by rotating the trim on an higher or lower setting.

This graph displays the improvement in performance on a Moto Guzzi V9 Bobber, thanks to the Rapid Bike Easy module. The power and AFR refer to a moderate throttle opening (30%), and this is where our entry level unit will make the biggest difference.
