Megaphones in Spark's dark style. Of the six pairs Spark builds for the T100 this is the loudest-looking shape in the quietest-looking finish, and at 928 euro it sits between the brushed stainless pairs at 856 and the Black Series ones at 1,012.
Key Features
- Pair of Megaphone slip-on silencers for the Triumph Bonneville T100, 2005 to 2015.
- Spark dark style finish.
- 3.5 kg for the pair.
- 928 euro — between the brushed and the Black Series pairs.
- Racing part, not approved for road use.
Dark Style Is Not Black Series
Spark runs two dark finishes and the price list keeps them apart. Black Series is the full black ceramic treatment, and Spark charges 1,012 euro for it on this motorcycle. Dark style is the lighter-touch option at 928.
Both take the shine out of the pipe. Which of the two is right depends on whether you want the exhaust to read as deliberately blacked or simply as not chrome — and on a classic, that distinction is larger than seventy euro suggests.
The Shape That Wears Dark Best
A megaphone is a big, wide, attention-seeking silhouette. In brushed stainless it announces itself twice, once by shape and once by brightness. In dark it announces itself once.
That is why this combination works on a T100 in a way an all-chrome megaphone sometimes does not: the outline still says racing, but the bike underneath is allowed to stay a Bonneville.
The Pair Spark Photographs
Worth mentioning because it is unusual. Spark publishes a single image for the GTR0207 number and it shows this dark version rather than the stainless one — so what you see on the product page is what arrives.
What Comes in the Box
Two silencers, mounting on the standard header pipes. Spark quotes 3.5 kg for the pair. The brushed stainless version of the same shape is GTR0207I at 856 euro.
Sound, Honestly
Spark gives no decibel figure for the T100 range and we will not put one on the page. The structural facts are enough: a racing silencer with an open megaphone outlet, replacing a factory can built to meet a road limit on a 865 cc twin.
The finish changes nothing about that. Dark style is a surface treatment, not a baffle.
Sold as a Pair
Both sides, in one article. Spark does not sell single silencers for this motorcycle, and on a bike with a symmetrical exhaust that is the right call.
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 stainless version of this pair is GTR0207I. The Trumpet shape is GTR0205I and GTR0205B, the Sinfonia GTR0206I and GTR0206B.
Road Approval
None. Spark lists this article as not approved. A dark finish does not change what an inspector is looking for.
