This new Ultra-Lite™ silencer for the Axys 850 was designed with the competition racer in mind. It provides a 9.3 pounds of weight savings. It also delivers improved throttle response and quicker acceleration. It passes the stationary sound test below 88 decibels but gives a more exciting sound at the higher RPM ranges (several decibels louder than our quiet version at wide open throttle). Throttle response is also improved slightly over our quiet silencer. Available in Satin Black and Polished Ceramic.
