Exhaust Sound: Aprilia Unveils New RS 457 Twin Cylinder Sportbike

April has introduced their latest sportbike, the RS 457, which features a twin-cylinder engine that's cooled with liquid. This engine is built with two camshafts sitting above and controls four valves in each cylinder, altogether producing a power of 47 horses. When it comes to how much this bike weighs without any fluids, it's just 350 pounds. This lightness plays a big role in how well it performs.
