Exhausts Triumph Speed Four

Four cylinders in line, 600 cc, sporting character declared from the very first glance: the Speed Four was Triumph's proposal for those who wanted a mid-displacement naked with a supersport DNA. Directly derived from the TT600, it shares its engine architecture but reinterprets it in a road-oriented key, with a chassis designed to offer genuine agility and a power delivery that rewards those who know how to use the rev range. A niche motorcycle, built when the market was asking for something different from the usual high-volume Japanese naked bikes. If you're looking for a sports exhaust to enhance it, you're in the right place: here you'll find our exhausts for Triumph, handcrafted to fit this specific platform.

The silencers in this category are designed to replace the original exhaust terminal in the lateral position, leaving headers and upstream connections unchanged. This is not a full exhaust system: the original muffler is removed and replaced with our sports silencer, which connects to the original mounting points via the fitting kit included in the package. The interface is plug-and-play on the existing connection, but for an optimal result and correct alignment it is advisable to rely on a qualified mechanic, especially when working on a motorcycle from this era that may have connections subject to wear.

The most immediate benefit is weight reduction: the original terminal on the Speed Four is certainly not known for its lightness, and replacing it with a titanium or carbon silencer results in a noticeable reduction in unsprung weight at the rear. On the sound side, the Speed Four's four-cylinder engine has a naturally metallic and lively tone at high revs: our exhaust terminal delivers a fuller and more defined sound across the entire operating range, with a more present character compared to the original without being intrusive in everyday use. On the performance side, smoother exhaust flow management can favour a more linear throttle response, particularly in the mid-to-high rev range where this engine expresses its best.

We manufacture each sports exhaust to order in our workshop with handcrafted manufacturing in Lombardy, in the province of Bergamo. Every piece goes through an internally controlled production cycle before shipping, with no intermediate steps. We operate as direct from the manufacturer: no resellers in between, which reflects both on product quality and on the ability to handle technical enquiries directly.

Every silencer comes with a standard dB killer fitted at the factory. Removing the dB killer invalidates the road homologation and is not permitted for road use. For those who prefer an even more contained sound profile, some models feature the No-Noise option: an internally welded filter that further reduces decibels without significantly affecting power delivery. Where available for the chosen model, it can be selected directly in the product page drop-down menu.

As this is an intervention limited to the terminal, the Speed Four's ECU does not normally require any mapping modifications. The original injection system adapts without issues to the change in back pressure introduced by the new terminal, making installation straightforward to manage without additional remapping.

Updated production times are visible directly at checkout, where the estimated shipping date is indicated. Once the order is shipped, a tracking code is automatically sent to follow the delivery.
