Designed for the Off Road, this exhaust is the ultimate in essentiality and purity of the lines. We are obviously talking about 4-TRACK R with removable dbk in the "SHORT" 300 mm version Racing. The link-pipe that connects the silencer to the primary collector is decatalized for a weight reduction of 2.21 kg. The support bracket is oversized and TIG welded manually by our specialized technicians and secured to the bike frame through a Silent-Block that dampens vibrations avoiding breakage to the weld itself. The silencer body is in stainless steel, 0.8 mm thick and octagonal shape. The stainless steel caps are watertight and secured to the body silencer by 10 reinforced stainless steel rivets. The exhaust gas exit is double with round shape while the spout is oval and obtained by hydroforming. The logo is laser engraved.
