This change does not trigger the engine warning light as the O2 sensors remain in place. There is also no need to reprogramme the ECU as it is self-adaptative on these bikes.
On Euro4 bikes you can also remove those sensors (with this kit) to facilitate cold-engine starts and idle, and simplify the bike's electrical system. This is not possible on Euro5 and Euro5+ bikes, for which the bypasses include fitting points for the O2 sensors.
Mounting
Medium-difficulty installation with basic tools - we recommend fitting by a professional unless you are an experimented DIYer.
Important notes:
- This change makes your non-compliant with the original bike, and as such it is not strictly legal for road use and the installation of this kit is your responsibility.
- NOT for USA, Canada, Australia and New Zealand (exhaust systems are specific in these countries).
