The Trumpet pair with the black ceramic treatment Spark calls Black Series. On a T100 — a motorcycle designed around chrome and polished alloy — a matte black exhaust is not a small decision, and 156 euro over the brushed version is the price of making it.
Key Features
- Pair of Trumpet slip-on silencers for the Triumph Bonneville T100, 2005 to 2015.
- AISI 304 stainless with black ceramic treatment.
- 3.5 kg for the pair.
- 1,012 euro against 856 for the brushed stainless version.
- Racing part, not approved for road use.
Ceramic, Not Paint
The distinction matters more on an exhaust than anywhere else on a motorcycle. Paint on a component that cycles from ambient to several hundred degrees blisters, lifts at the edges and eventually flakes off in sheets. A ceramic layer is cured into the surface and does none of that.
It also stays matte and even. Bare stainless goes through a straw-to-blue heat tint near the header joint within a few thousand kilometres; a ceramic-treated pipe looks the same in year five as it did in the crate.
Black on a Chrome Motorcycle
The T100 is a bike with a lot of bright metal on it — mudguards, headlight shell, fork sliders, engine cases. Two black pipes low on the right change the balance of that: the eye stops travelling along the bottom of the machine and goes to the tank and the wheels instead.
It is the same decision café-racer builders have been making since the sixties, and Spark simply sells it finished rather than leaving you to a rattle-can.
The Shape Underneath
Identical to GTR0205I: a long, slim body with a gentle taper and a slight flare at the mouth. Only the surface changes, which makes this a purely visual choice — the weight, the fit and the sound are the same.
Keeping It Black
Ceramic is tough but it is not indifferent. Degreasers and the aggressive chemistry in car-wash products attack the surface over time, and a black pipe that has been scrubbed with the wrong thing goes patchy in a way a brushed one never does.
Warm water, a mild soap and a soft cloth is the whole maintenance routine. Done that way the finish outlasts the tyres several times over, and it survives winter salt better than bare stainless does.
Installation
Slip-on level: the standard silencers come off and Spark's go on in their place, with the header pipes untouched. On a T100 that is a bolt-on afternoon rather than a workshop job.
Fitment & Compatibility
Triumph Bonneville T100, 2005 to 2015. The brushed stainless version of the same pair is GTR0205I at 856 euro. The Sinfonia shape is GTR0206I and GTR0206B; the Megaphone is GTR0207I and GTR0207D.
Road Approval
None. Spark lists this article as not approved, and a Bonneville is a road bike far more often than a track one. Worth settling before you order.
