Thirty seven miles of closed public road, stone walls at arm's length, and a mountain section that has ended careers. The bikes that won there were not the heaviest, the quietest, or the most cautious.\u003c\/p\u003e\n\u003cp\u003eThe 2025 Speed Twin 1200 is a performance focused modern classic, and riders who choose it are not looking for stock. Stock is what they get on the exhaust, because that is what the factory has to ship. The mufflers are heavy, quiet, and visually restrained, and they hold back the character the 1200cc twin can deliver.\u003c\/p\u003e\n\u003cp\u003eThe Two Stage Core runs two baffles at two different diameters to control flow in sequence, so mid range torque survives corners, rolling throttle, and city traffic, which is exactly where the Speed Twin lives. The Dimpled Baffle brings out the engine's natural voice. At 2.4 pounds per silencer it also drops real weight off the back and sharpens how the bike moves.\u003c\/p\u003e\n\u003cp\u003eThe TT is loud. That is the design, not a side effect, and it does not accept a dB Killer. If quiet matters more to you than volume, look at the Predator Pro instead, which takes an optional dB Killer.\u003c\/p\u003e","brand":"British Customs","offers":[{"title":"Default Title","offer_id":42113443397728,"sku":"BC902.2.119-BS-BR","price":599.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2384\/1971\/files\/builder-series-slip-on-exhaust-triumph-speed-twin-1200-2025-plus--03.jpg?v=1762439375","url":"https:\/\/britishcustoms.com\/products\/builder-series-tt-slip-on-exhaust-speed-twin-1200","provider":"British Customs","version":"1.0","type":"link"}
