Roadsitalia Motorcycle Exhausts Shop

In this section you will find add-on ECUs and lambda kits designed to optimize the performance of your motorcycle.
The ECUs allow better management of fueling and power delivery, improving response and overall performance.
The lambda kits, on the other hand, work on the second lambda sensor to eliminate the check engine light (error code P0420) and optimize the parameters sent to the ECU, making the bike smoother and more enjoyable to ride every day.
These devices are plug & play, require no permanent modifications, and are ideal both for riders using the bike on track without a catalytic converter and for those who want to further optimize throttle response even with a catalyzed exhaust.
There are 3 products.
