All products are HOMOLOGATED FOR ROAD USE (Approval valid throughout Europe and Switzerland).
Made in Italy 100% in our workshop.
CATALYZED VERSION
If you wish to obtain full homologation for road use, you must select CATALYZED: "YES" from the product combinations. Selecting CATALYZED: "NO": the sports exhaust will be supplied without catalytic converter so the emissions and the sound emitted will only be suitable for use on private roads or on the track.
Important note: To ensure the optimal performance of the sport catalytic converter and allow it to reach maximum efficiency, we recommend carrying out a short break-in cycle of approximately 50 km after installation. The break-in should consist of city use with variable engine speeds, avoiding prolonged constant revs (no highway use during the first 50 km).
ECUS, DIAGNOSTICS & LAMBDA KITS
Whether you choose the decat version, aware of the possible P0420 error and activation of the MIL warning light, or prefer to keep the catalytic converter while still aiming for maximum performance, we offer the ideal solution to optimize your motorcycle and ride with peace of mind.
In this scenario, the LAMBDA OPTIMIZER + AMC AUTOMATIC MIL CLEAR KIT comes into play, designed to optimize low and mid-range engine response and automatically manage the MIL warning light (Check Engine) via the OBD diagnostic port.
The Lambda Optimizer connects inline with the second lambda sensor to improve throttle response; AMC Automatic MIL Clear operates at diagnostic level, automatically switching off the warning light and managing faults such as P0420, without modifying engine parameters or performance.
Euro 5+ models may feature a particularly sensitive second lambda sensor: in some cases MIL activation has been observed even with catalytic systems or fully stock motorcycles, for example after a simple wash. For this reason, many riders choose this kit for additional long-term peace of mind.
If you only wish to eliminate the warning light (without performance optimization), you may consider the UNIVERSAL MIL ELIMINATION KIT EURO5+, which automatically keeps the warning light off when connected to the diagnostic port.
Do you want to read and manually clear existing fault codes and monitor your motorcycle data?
With the DIAGNOSTIC KIT you can monitor ECU parameters in real time from your smartphone.
