There is no bright edge at the tip and no highlight running along the body — the silencer registers as an outline rather than an object.\u003c\/p\u003e\u003cp\u003eAgainst a T120 in Jet Black this is close to invisible from ten paces. Against one of the two-tone colourways it becomes a dark line under the tank stripe, which is roughly what the factory pipework does but in half the weight.\u003c\/p\u003e\u003ch2\u003eThe Coating, and What It Costs\u003c\/h2\u003e\u003cp\u003eBlack Series is a ceramic treatment applied over the same stainless component, not a lacquer. It is bonded to the metal, so the heat of a silencer does not lift it or turn it brown at the hot end the way high-temperature paint tends to after a season or two.\u003c\/p\u003e\u003cp\u003eIt carries a 156 euro premium over the brushed GTR0209IOM. That is the entire difference between the two article numbers — the bodies, the pipes, the brackets and the approval are shared.\u003c\/p\u003e\u003ch2\u003eEuro 4, Issued in Italy\u003c\/h2\u003e\u003cp\u003eThe type approval for this pair was released by the Italian Ministry of Transport and covers the silencers as supplied, mounted downstream of the motorcycle's own catalytic converter. Nothing is removed from the emissions path.\u003c\/p\u003e\u003cp\u003eFor an owner who wants the exhaust to look modified and the documents to look standard, that combination is the point of the article.\u003c\/p\u003e\u003ch2\u003eKeeping It Black\u003c\/h2\u003e\u003cp\u003eA ceramic surface wants mild soap and a soft cloth, and nothing abrasive. Metal polish, cutting compound and the harsher wheel cleaners are all designed to remove material, which is the opposite of what a coated exhaust needs.\u003c\/p\u003e\u003cp\u003eLeft alone and washed normally, the finish stays even. The failure mode people report with black exhausts almost always traces back to something aggressive applied to them.\u003c\/p\u003e\u003ch2\u003eMedium Revs, Which Is Where It Is Ridden\u003c\/h2\u003e\u003cp\u003eSpark states the performance improvement at medium engine speeds. On a big, torque-forward parallel twin that is where the useful part of the range sits, and it is a claim that describes ordinary riding rather than a dyno peak.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eTriumph Bonneville T120, 2016 to 2018.
