The exhaust has a removable db killer (noise limiter) for racing use; removing the db killer is not ONLY illegal, but the customer assumes responsibility for using the bike as if on the track only, without panniers, without flashlight, and without number plate holder or other parts that would interfere with the different gas angle due to the transformation into a racing version. Misuse of this situation on the road will result in the loss of the product warranty. From the 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 re-mount the original exhaust or wait the standard time for repair.
