The grin-inducing roar of the MT-09 is one of its most defining characteristics, evoking a sense of pure adrenaline with every twist of the throttle.The MT-09 features specifically designed air-intake ducts which accentuate the high frequency sounds, which are then emphasised, especially at higher speed, by an acoustic amplifier grille on top of the fuel tank, delivering the CP3's vibrant note directly to you.
