Actually here is a video of the bike...
http://www.motorcycle.com/shoot-outs/2011-literbike-streetfighter-shootout-90928.html?page=3Music to a gearhead’s ears is the snort from the engine’s intake – it paints an aural picture of the formidable forces the Kawi is producing. Kevin said the sound emanating from the intake made a “rambunctiously wonderful honk” when hard on the gas, and that it made him forget for a minute “about the enviable sonic qualities of fitting an aftermarket exhaust.”
Positioning the ducts close to the rider allows the intake sound to be heard - and enjoyed - by the rider
A resonator inside the airbox reduces noise at low rpm, and enhances intake sound at high rpm
Good grief! Open that throttle a bit and around 7k+ you'll hear it! Sounds awesome.
