Altering the db killer welds or anti-tamper screws or removing the fixture is illegal for road use and not compliant with EU regulations; this is only possible for RACING use on tracks. Using the open version on the road is not compliant with public road traffic regulation.
WARNING: this item is approved for noise; the customer must first check if the original catalyst or GPR catalyst is required in their country to comply with road traffic regulation and for annual inspection.
You can use the kit for the official annual inspection.
Installation recommendations: GPR products are plug and play, but it's still recommended to install the products in a professional workshop; no claims will be accepted in case of incorrect installations.
The specific approval certificate is provided, along with the installation instructions; each silencer has the approval code. If any issues occur during installation, it is mandatory to stop and suspend activity and immediately seek information and/or advice from customer service.
Is it limited to 95dB for Tyrol and Switzerland? No, but this limit is only required for local citizens and not for tourists.
No structural modifications to the motorcycle are required for installation to use the product in an approved version. It is advised to read the instructions in the package or the visible tutorials and those on YouTube.
The exhaust has a removable db killer (noise limiter) for use in races; removing the db killer is not ONLY illegal, but the customer assumes responsibility for using the motorcycle as on the track only, without bags, without flashlights, and without registration plate support or other parts that would conflict with the different gas angle due to converting to a racing version. Abuse of this situation on the road will result in loss of product warranty. From the moment of purchase, with the right to repair with return to the GPR factory or the nearest official distributor at the customer’s expense.
GPR cannot provide a new silencer instead of the one to be repaired; the customer must agree to reinstall the original exhaust or wait the standard time for the repair.
