Yoshimura is ready with a performance Race Series system that will make this model's little fuel-injected engine come alive! Gone is the weight of that ugly muffler box, so Yoshimura performance can be bolted up! The RS-2 Mini is the perfect fit for this little fun machine. It adds torque and horsepower while removing the unwanted weight of the under-performing stock system. This new system features Yoshimura's proprietary Works Finish that adds style and durability. With the RS-2 mini Race Series system, your bike can now reach its full potential. Add the new Yoshimura Fender Eliminator Kit and you can't go wrong! Diamond-shaped sleeve. Large core and increased muffler packing volume means quieter operation. Stainless steel cone end-cap. Stainless steel header and tail-pipe.
