TRIUMPH STREET TRIPLE S 660 - A2 (2020-2022)S1 Muffler, Titanium, with s-shaped connection with welded sector curves

The S1 muffler, a benchmark for the Superbike World Championship, is available with a titanium tapered body and matt carbon fibre end cap and, depending on the model of motorcycle, with the spectacular titanium flame arrester on the output.

The S1 muffler fuses a racing style with valued technical solutions such as bracket and fitting welding with T.I.G. technology or titanium insert bushings machined from solid by CNC machines, which guarantee impeccable couplings.
The S1’s tapered body, together with the diameter of the output and the particular internal soundproofing, gives the bike on which it is fitted a dark and unmistakable sound.
