Spark Exhaust Force Evo 350 mm WSSP Titanium Link Pipe Group Triumph Daytona 765 Moto 2 (2019-2023) GTR8823ST

The short Force Evo on a titanium link pipe. Spark's WSSP replica group in its most compact form — 350 mm of silencer behind a carbon-covered titanium pipe, for a Daytona already running a Spark collector.

Key Features

• Titanium link pipe with carbon cover and 350 mm Force Evo silencer.
• Triumph Daytona 765 Moto 2, 2019 to 2023.
• Fits only Spark's GTR8815 or GTR8817 collector.
• Force Evo: titanium case with a rib converging into the carbon end cap.
• The shortest silencer group Spark offers on this collector.
• Takes the G9999 dB killer.

Three Hundred and Fifty Millimetres

Spark builds the Force Evo in two lengths for this collector: this 350 mm case and the 400 mm of GTR8827ST. Fifty millimetres does not sound like much until you remember what a silencer uses length for.

Absorption is a function of the distance the gas travels through packing. The shorter case is lighter, ends sooner behind the rear wheel and looks tighter on a bike as compact as the Daytona; the longer one is what Spark offers when a circuit measures. On an unrestricted track day the short case is the better-looking half of that trade.

The Rib Is the Tell

Force Evo and Konix Evo are easy to confuse in a photograph and easy to tell apart in person. The Force Evo carries a rib along the titanium sleeve that runs into the lines of the carbon end cap; the Konix Evo is a smooth conical case.

Spark uses the Force Evo where sound level is part of the brief — it is the silencer on the factory Endurance World Championship system — and the Konix Evo where the case has to look finished. On a Daytona 765 Moto 2 either is defensible; the Force Evo is the quieter half of the pair.

What It Will Not Fit

The restriction is printed in Spark's own part description: this group is for the GTR8815 or GTR8817 collector only. It is not a slip-on and it will not mount to the standard Triumph headers.

A Daytona still on its standard collector needs either the complete GTR8815T system, or a collector plus one of these groups. Buying the group alone in the hope it will adapt is the one mistake this page exists to prevent.

Why the Daytona Gets Its Own Numbers

Spark lists this group and its Konix Evo twin against the Daytona 765 Moto 2 alone, while the newer GTR8828ST and GTR8827ST cover the Daytona and the Street Triple together. The collector interface is the same, so the practical difference is which generation of the range a part belongs to rather than which motorcycle it will physically fit.

If you are ordering for a Daytona, either pair works. If the same collector might later move to a Street Triple, the newer groups are the ones Spark lists for both.

Fitment & Compatibility

Triumph Daytona 765 Moto 2, 2019 through 2023, on the Spark GTR8815 or GTR8817 collector only. The Konix Evo version of this group is GTR8817ST. The current-generation groups are GTR8828ST and GTR8827ST. The complete Moto2 replica system is GTR8815T.

Road Approval

None. No EC certificate and no catalytic converter anywhere in the system. Closed circuits only.
