With a 200bhp+ 1,000cc V4, it’s no surprise that the 2009 Aprilia RSV4 sounds like a race bike (It’ll compete in SBK), what is a surprise is just what kind of race bike it sounds like. After the jump you’ll find two videos, one of it being started up and idled at its official presentation back in February, and one of it lapping Mugello in anger.
At 1:47, the engine’s sound appears to get considerably louder, we
don’t know the reason for this. It could be because the cameraman
adjusted his microphone, it could be because Aprilia is trying out
different exhausts or even firing orders, and it could be because it’s
an entirely different bike, but it doesn’t look like that’s the case.
You be the judge.
