No structural modifications to the bike are required for installation to use the product in an approved version. It is recommended to read the instructions in the package or the tutorials available on YouTube.
For online purchases, it is necessary to activate the warranty by sending the appropriate coupon stamped by the installation workshop via email to certificato@GPR.it. For physical purchases, a stamp from the shop is sufficient. 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 on the track only, without bags, without flashlight, and without license plate holder or other parts that would conflict with the different throttle angle due to the modification to the racing version. Abuse of this situation on the road will result in loss of product warranty. From the date of purchase, there is a right to repair with return to GPR factory or the nearest official distributor at the customer's expense.
GPR cannot provide a new silencer in place of the one to be repaired; the customer must agree to reassemble the original exhaust or wait the standard time for the repair.
The new GPR Grand Prix Evo Titanium silencer has been created to celebrate its 20 years of presence in MotoGP/Moto2/Moto3 world championship. The first Grand Prix line was presented in 2005, coinciding with the debut of the Konica Minolta team and rider Makoto Tamada, as well as the LCR team and rider Casey Stoner. The silencer is tapered, with a special shape, ranging from a diameter of 90 mm to 130 mm in circumference and a variable length depending on the motorcycle. It features a natural colour titanium sleeve, a CNC machined black end cap with a pentagonal outlet, and a silencer.
