A megaphone does not taper towards the outlet — it opens out, widening all the way to a large mouth, and it is the silhouette that says racing before anything else about the motorcycle does.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePair of Megaphone slip-on silencers for the Triumph Bonneville T100, 2005 to 2015.\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel.\u003c\/li\u003e\n\u003cli\u003e3.5 kg for the pair.\u003c\/li\u003e\n\u003cli\u003eHeader pipes stay standard.\u003c\/li\u003e\n\u003cli\u003eRacing part, not approved for road use.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhy a Megaphone Looks Like That\u003c\/h2\u003e\u003cp\u003eThe shape is not a stylist's invention. Open megaphones were what racing four-strokes ran before absorption silencers existed, sized so the expanding cone helped scavenge the cylinder rather than to quieten anything. Spark's version is a silencer built in that outline rather than a true open megaphone, but the proportions are the same.\u003c\/p\u003e\u003cp\u003eOn a Bonneville the effect is immediate. Where the Trumpet and the Sinfonia let the bike stay a road motorcycle, a pair of megaphones turns it into something that looks like it belongs at Goodwood.\u003c\/p\u003e\u003ch2\u003eThe Widest of the Three\u003c\/h2\u003e\u003cp\u003eWorth thinking about physically as well as visually. The mouth is larger than on either of the other shapes, so the can sits closer to the rider's boot and closer to a pillion's. On a bike used two-up, the Sinfonia is the more considerate choice.\u003c\/p\u003e\u003ch2\u003eA Note on the Photograph\u003c\/h2\u003e\u003cp\u003eSpark publishes one image for this article number and it shows the dark version, GTR0207D. We have not attached it to this listing, because a photograph of a black silencer on a page selling a stainless one is the kind of thing that only becomes clear when the parcel is open.\u003c\/p\u003e\u003cp\u003eIf you would like to see the brushed pair before ordering, ask us and we will get a picture from Spark.\u003c\/p\u003e\u003ch2\u003eWhat You Are Buying\u003c\/h2\u003e\u003cp\u003eAISI 304 stainless, supplied as a pair, mounting on the standard header pipes. The dark version of the same shape is GTR0207D at 928 euro — seventy-two euro more, and the one Spark photographs.\u003c\/p\u003e\u003ch2\u003eSound, Honestly\u003c\/h2\u003e\u003cp\u003eSpark publishes no decibel figure for any of the T100 slip-ons, and we are not going to invent one. What can be said is structural: these are racing silencers replacing heavily baffled factory cans on an 865 cc parallel twin, and the difference is not subtle in any of the three shapes.\u003c\/p\u003e\u003cp\u003eOf the three, a megaphone has the least restrictive outlet. Draw your own conclusion, and if your riding is mostly through villages at seven in the morning, draw it carefully.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eSlip-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.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eTriumph Bonneville T100, 2005 to 2015.
