for YAMAHA R1 2004

Supersport motorcycles like the Yamaha R1 call for top-quality aftermarket components, and the Akrapovic RACING / EVOLUTION systems definitely rank in that category. Installing one of these systems will make the engine come alive, with a huge 160.7 HP delivered to the rear wheel way up at 12730 rpm. Experienced riders and racers will be able to maximize the advantage offered by the Akrapovic RACING (stainless steel) and EVOLUTION (titanium) exhaust systems. In addition to the increased performance, the visual effect is also dramatic, as the systems fit right in to the sharp lines of the Yamaha.
