The exhaust has a removable db killer (noise limiter) for racing use; removing the db killer is not ONLY illegal, but the customer assumes the responsibility of using the bike as if on the track only, without bags, without flashlights and number plate holder or other parts that would conflict with the different throttle angle due to the conversion to the racing version. Abuse of this situation on the road will result in loss of product warranty and any claim will be rejected. From the time of purchase, there is a right to repair with return to the GPR factory or to the nearest official distributor at the customer's expense.
GPR cannot provide a new silencer instead of the one being repaired; the customer must agree to reattach the original exhaust or wait the standard time for repair.
