Unleash the full power and the pithy, bubbling motocross and supermoto sound of your Aprilia SX 125! If you also remove the dB-killer from your Radical Racing rear silencer, the whole thing is no longer for weak people on the chest or people with pacemakers. So you better leave your grandpa at home! Basically you have a full length pipe with full power and minimal to no damping.
So the Puren Radical Racing Sound as it should be!
