This exhaust system was developed especially for the BMW S 1000 RR motorcycle. The aim was to increase the performance of the engine, while at the same time reducing the weight of the machine. To achieve this, the system, which weighs only 4.1 kg, uses lightweight titanium alloys and a handcrafted carbon-fibre end cap, which also lend the system its distinctive appearance. The shape of the exhaust system continues the expressive lines of the machine and coherently blends into the sporty design of the ­motorcycle.
