Constructed completely from lightweight, high-grade titanium, this system offers a weight saving of 23.8 % (0.9 kg) over the stock exhaust.Gasgas: To install the silencer, the stock mounting parts must be overtaken.

ATTENTION: When used on EU models from MY26 and US models from MY26 FACTORY EDITION / MY27 Standard, the air box and air filter must be reverted to MY25. The correct engine mapping must also be installed. Vehicles in this configuration no longer comply with the 109 dB FIM noise limit.

The weight of the Akrapovič „Evolution Line" exhaust system is just 4.6 kg.
Compared to the standard exhaust system it offers a weight saving of 5 kg!
The power gets increased to 135 hp.
The torque gets increased to 106 Nm.
Noise level of this exhaust system: 102,5 dB(A)
Static noise measurement like performed on race tracks (at 5.000 rpm)
The Akrapovič-kit „Evolution Line" can only be used in combination with the specific engine mapping. It is technical wise not possible to use this specific engine mapping respectively the Akrapovič „Evolution Line" exhaust system on the public road.
All indicators need to get disconnected before the engine can be started.
Also the cruise control is deactivated.

Only applicable for 990 Duke R:
When installing the adapted engine mapping (EFI file) for the Akrapovic ""Evolution Line"", also another feature get`s enabled: Engine Brake Control (EBC).With this feature it is possible to increase or decrease the engine brake characteristics of the bike. It can be adjusted in 5 levels (-2 / -1 / Standard / +1 / +2).
