DescriptionThe whole story▼
Thirteen decibels. That is the gap between Triumph's standard exhaust at 93.5 dB and this silencer at 106.4, both measured at 5,850 rpm, and it is the figure that decides whether this part suits a given rider. Nothing else on this page matters as much.

- Static noise of 106.4 dB against a standard 93.5
- Three quarters of an hour to fit
- No type approval — closed circuits only
The Euro 5 Generation
Triumph reworked the 765 triple for 2020 to meet Euro 5, changing the exhaust and the engine internals in the process. This part number belongs to that revision. The earlier 2017 to 2019 bikes take S-T7SO2-APC, and the two are not interchangeable.
Worth stating plainly: Akrapovic publishes exactly the same weight, power, torque and noise figures for both part numbers. Whether the later engine truly behaves identically or the earlier dyno sheet was carried across, the manufacturer does not say. The numbers here are the ones Akrapovic gives for this part.
Four Point One Kilograms
The standard system is a heavy thing — 6.7 kg with its catalytic converter and shielding. What replaces it weighs 2.6. On a motorcycle of roughly 189 kg, shedding that much from the right-hand side and above the swingarm pivot is felt in how quickly the bike stands up out of a turn.
Carbon Rather Than Titanium
Akrapovic offers this silencer with a carbon fibre sleeve. Carbon is lighter than titanium for the same stiffness and it does not discolour with heat, but it scuffs where titanium would only mark. On a track bike that is a fair trade; on a machine that gets ridden through winter it is worth thinking about.
Four Bikes, One Silencer
Triumph sold the 765 triple as the Street Triple S, R and RS, and as the Daytona Moto2 765. They differ in suspension, brakes and state of tune, not in the exhaust route, so a single part covers the set.
Three Quarters of an Hour
Forty-five minutes is longer than a plain silencer swap because the standard part is a full under-engine assembly rather than a can on a hanger. It is still within reach of a home workshop with the bike on a paddock stand.
The Approval Question, Settled
There is none. Akrapovic states that this product does not meet emission compliance requirements for street or highway use. A Street Triple with this silencer fitted is a track motorcycle, and no amount of paperwork changes that.
Riders who want the sound on the road need the road-legal route instead; this catalogue lists complete systems for the same machines that keep their approval.
Road Approval
None. For closed course competition use only.
