Arrow X-Kone Silencer KTM RC390
X-Kone silencers were designed at first to be used in our Competition and Competition Full Titanium systems. The internal structure of the silencer is in stainless steel, silencer body is in Nichrom (an alloy with stainless steel) with satin finish. Secured to the frame by means of a mount welded on the upper side of the body. Noise damping is achieved by absorption: this enables to reduce the weight and the dimensions of the silencer: the weight of the silencer is about 2.2kg, typically 30/40% less than the OE. Requires Arrow midpipe for stock collectors.
