Constructed with a lightweight titanium muffler outer sleeve, stainless-steel link pipe, and pre-muffler, and finished with a handmade carbon-fibre endcap, the exhaust offers an enormous 21.6% weight savings over the standard stock version. Through innovative design it fully integrates into the lines of the bike with a small and compact build for a powerful visual effect. Its full and vivid sound is a deep, sporty rumble, making the twin-cylinder powerplant pulse with a harmonious rhythm, all within the confines of a Euro 5 engine. A perfect throttle response offers the feel of performance. Fully EC/ECE type approved, it is a simple plug-and-play installation with no remapping needed. Fully compatible with BMW side cases and the central stand, the entire Akrapovi? system can be further upgraded by adding an optional handmade carbon-fibre heatshield.
