Article information
Pro-Race
Pro-Race silencers design comes from the first prototypes made for MotoGP. Pro-Race silencers are built putting together a conical-shaped part (the main body of the silencer) with a cylindrical ending section (ø98mm) and these are available in titanium or nichrom (a stainless steel alloy).
The silencers are secured to the bike by means of mounts welded to the main body, their cone-shaped design provides a reduction of dimensions and weight, but it also reduces the overall volume of the exhaust, thus limiting noise damping capabilities and the application on bigger or demanding engines.
Pro-Race silencers are available both in a street legal and racing version, with removable baffle.
