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 included in the package or the tutorials available 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, a stamp from the store 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 only on the track, without saddlebags, without a flashlight, and without a license plate holder or other parts that would conflict with the gas angle due to the conversion to race version. Abuse of this situation on the road will result in forfeiture of the product warranty. From the time of purchase, there is a right to repair by returning it to the GPR factory or the nearest official distributor at the customer's expense.
GPR cannot provide a new silencer to replace the one being repaired; the customer must accept reinstalling the original exhaust or waiting the standard time for the repair.
The new Grand Prix Evo Black Titanium silencer from GPR has been 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 variable length depending on the motorcycle. It is equipped with a black titanium sleeve treated to withstand high temperatures, and CNC machined end caps with a pentagonal outlet and db killer.
