The Triumph Street Twin 900 is where it starts for so many modern classic riders. Accessible, genuinely stylish, and powered by one of the most characterful parallel twins Triumph has ever built. It's also one of the most satisfying bikes to personalise, and our reverse cone slip-ons are one of the best places to start.
The reverse cone shape lets the exhaust gases expand before they exit the muffler, giving the Street Twin a noticeably deeper and more rounded sound than stock. Removable DB killers are included, and these slip-ons mount straight onto the original headers using the stock hardware. No modifications, no remapping needed.
