@ermigeorge Hi...in fact, the exhaust valve is quite closed on the neutral. When you put a gear the sound become louder because the valve is opening. The new V4 Models 2011 equiped with the APRC does not work with the same way. APRC models are subject to new standards Euro 4. In this case the valve does not open at the start of a running gear but later in high revs. The sound still amazing.....
One person can't buy this machine and is jealous.

Ur a serious retard. This is the pipe that Aprilia's WSBK team uses, and the company that Biaggi used on his bike!
