Spark Exhaust Konix Evo Euro5+ Full System Lateral Mount Triumph Street Triple 765 (2023-2026) GTR8826TOM

The silencer up beside the tail instead of under it. Spark's laterally mounted Euro5+ full system for the Street Triple 765 MY23-26, closed by the Konix Evo — the titanium case with the carbon end cap drawn with a design studio in Maranello.

Key Features

• Euro5+ homologated full system for the Triumph Street Triple 765 R, RS and S, 2023 to 2026.
• Lateral silencer mounting.
• Konix Evo: all-titanium case — sleeve, perforated inner tube and inner end cap — with a carbon end cap.
• 6.8 kg against 9.6 kg standard.
• Catalysed 3-in-1 pipe, AISI 304 collectors, CNC-machined connections.
• No ECU modification required.

Where the Silencer Sits

Spark builds this system in two mounting positions and the difference is entirely visual and ergonomic. The low mount tucks the silencer under the tail unit, close to the swingarm; the lateral mount carries it out and up beside the seat.

Low keeps mass central and leaves the rear of the bike clean. Lateral puts the silencer where people see it, which on a naked bike is the point — there is no fairing to hide behind, and the exhaust is a visible part of the design rather than plumbing. Neither position changes the homologation or the catalyst.

Konix Evo Instead of Grid-O

The Grid-O is the racing case: full titanium, TIG welds left on show, a titanium grid, and the silencer that took the 2020 Moto2 title. The Konix Evo is the finished one — the same titanium construction right down to the perforated inner tube and inner end cap, closed by a carbon end cap styled with a Maranello design centre.

Both are homologated in this system, so the choice is not about legality. It is whether you want an exhaust that looks like it came off a race bike or one that looks like it was designed for this one.

What the Weight Tells You

At 6.8 kg this is the heaviest of Spark's three homologated systems for the bike — the low-mount Grid-O version is 5.9 kg and the lateral Grid-O is 6.1 kg. All three replace a 9.6 kg standard exhaust.

The extra comes from the mounting hardware a lateral silencer needs and from the case itself. If grams are the priority, GTR8824TOM is the one. If the look is, this is.

Installation

The system replaces the standard exhaust in full, from the cylinder head back — on the MY23-26 bike the original is a single piece, so there is no shorter route. The kit carries two lambda sensor bosses and a plug for the second, so it fits both the single- and dual-sensor machines Triumph built in this run.

No ECU work is needed: Spark developed the homologated systems to raise performance without a remap, which keeps the dealer network out of it and the warranty conversation short. Spark's installation sheet is under Downloads on this page.

Fitment & Compatibility

Triumph Street Triple 765 R, RS and S, 2023 through 2026. With the black ceramic-treated box it is GTR8826BOM. The lateral Grid-O version is GTR8825TOM, the low-mount Grid-O GTR8824TOM. The G9999 dB killer fits the Konix Evo case.
