Spark Exhaust Force Evo EVO2024 Full Titanium Racing System 102 dB Kawasaki ZX-6R / ZX-6R Ninja / Ninja ABS 636 (2009-2026) GKA8834T

Built to a number. Spark designed this version of its EVO2024 system around the 102 dB limit that most circuits enforce, and put the Force Evo silencer on the end of it - the case with the ribs running back to a carbon end cap.

Key Features

• Full titanium racing system for the Kawasaki ZX-6R, ZX-6R Ninja and Ninja ABS 636.
• Force Evo silencer: titanium body with converging ribs, carbon fibre end cap.
• Designed to stay inside the 102 dB noise limit.
• Carbon fibre cover on the connection.
• 4.0 kg against 11.2 kg for the standard system.
• FIM-approved for the SSP600 category. Not road approved.

The 102 dB Question

Track days and club racing are governed by static noise limits, and 102 dB is the figure that keeps coming up across European circuits. An exhaust that misses it does not get a slower lap - it gets sent back to the paddock.

Spark says explicitly that this configuration is designed to optimise performance while staying inside that limit. That is a different brief from the Grid-O version of the same collector, which Spark offers for riders who have no noise restriction to meet and want the sound. If you do not know which category your circuit runs, this is the safer of the two.

The Ribbed Case

Force Evo is recognisable without reading the label: the titanium body carries ribs that converge towards the end cap rather than running parallel, which is what gives the silhouette its taper. The end cap itself is carbon fibre, and a second carbon cover sits over the connection to the collector.

The ribs are not decoration in the usual sense - a ribbed sleeve is stiffer than a plain one of the same wall thickness, which is how the case stays light without ringing.

Four Kilos, Not Three and a Half

The Konix Evo build on the same titanium collector, GKA8831T, comes in at 3.5 kg. This one is 4.0. Both cost the same 2,494 euro, and both remove more than seven kilos from the motorcycle, so the half-kilo between them is the sort of difference that matters only if the rest of the decision is already tied.

The real difference is the noise brief. Konix Evo is the design-led choice, Force Evo is the one engineered against a limit.

What Titanium Buys Here

The collector is titanium rather than the AISI 304 stainless Spark uses on its 60 mm kits for the same motorcycle. That is where most of the weight saving sits, and it is also why this range costs roughly a thousand euro more than the steel systems.

Fitment & Compatibility

Kawasaki ZX-6R, ZX-6R Ninja and Ninja ABS 636, 2009 to 2026. The Konix Evo version of this system is GKA8831T and the unrestricted Grid-O version is GKA8833T. Titanium kits without the carbon covers are GKA8829T and GKA8832T. The stainless 60 mm systems are GKA8806T and GKA8822T.

Road Approval

None. Spark lists this article as not approved for road use. The FIM SSP600 approval is a racing homologation and does not cover public roads. Closed course.
