No structural modifications to the motorcycle are required for installation in order to use the product in an approved version. It is recommended to read the instructions in the package or the tutorials available online and on YouTube.
For online purchases, it is necessary to activate the warranty by sending the appropriate stamped coupon from the installation workshop via email; for physical purchases, the shop stamp is sufficient. The exhaust features a removable db killer (noise limiter) for race use; removing the db killer is not ONLY illegal, but the customer assumes responsibility for using the motorcycle as on the track only, without luggage, without flashlight and license plate holder or other parts that may conflict with the different gas angle due to the conversion to race version. Abuse of this situation on the road will lead to loss of the product warranty. From the date of purchase, there is a repair right 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 reinstall the original exhaust or wait for the standard time for repair.
The new Grand Prix Evo Titanium silencer from GPR was created to celebrate its 20 years of presence in the MotoGP/Moto2/Moto3 World Championship. The first Grand Prix line was presented in 2005, at the debut of the Konica Minolta team and rider Makoto Tamada, as well as the LCR team and rider Casey Stoner. The silencer is conical, with a special shape ranging from a diameter of 90 mm to 130 mm in circumference and a length that varies according to the motorcycle. It is equipped with a natural colour titanium sleeve, a black CNC machined end cap with pentagonal outlet and a silencer.
