Four and a half kilos, out of an exhaust system. The standard assembly on a ZX-10R of this generation weighs 9,3 kg; this one weighs 4,9. Spark calls it the Superbike version and measures it at 102 dB, which puts it inside most European circuit limits without an insert.
Key Features
- Racing full system for the Kawasaki ZX-10R, 2011 to 2020.
- Collector in AISI 304 stainless steel, 65 mm.
- Force silencer, 350 mm, titanium.
- 4,9 kg against 9,3 kg for the standard system.
- 102 dB — Spark's Superbike specification.
- Racing part, not approved for road use.
Stainless Where It Counts, Titanium Where It Shows
The collector is AISI 304 at 65 mm diameter, not titanium. That is a deliberate choice for a racing system: the collector is the part that gets kicked by a foot peg in a crash, that takes the heat cycling closest to the head, and that a rider is most likely to have to straighten in a paddock rather than replace.
The silencer is titanium, 350 mm long, in the Force shape. That is where the weight saving and the visible part of the article sit.
102 Decibels, and What It Buys
Circuit noise limits in Europe are enforced at the gate, and a bike that measures over is sent home. Spark states 102 dB for this system, and that number is with the silencer as supplied — no dB killer to fit, nothing to leave in place for scrutineering and take out for the session.
102 sits comfortably under the 107 dB ceiling applied by the French championship and the Endurance World Championship, and under the limits most club days work to.
Two Generations, One Article
Spark lists this system for the ZX-10R of 2011 to 2015 and of 2016 to 2020. The exhaust routing on the two is close enough for one collector to serve both, which is unusual across a model change of that size and worth knowing if the bike is a mixed-year track machine.
It does not fit the 2021 and later ZX-10R and RR. Those take the GKA8853T titanium system or the GKA8854T three-quarter kit.
The Half of the Weight That Is Not Metal
The 4,4 kg difference is not only material. The standard system carries a catalytic converter, its housing, and the shielding around it — and all of that goes when a racing system replaces it. That is also exactly why this article cannot be registered for the road.
Fitment & Compatibility
Kawasaki ZX-10R, 2011 to 2020. Not for the 2021-on ZX-10R and ZX-10RR — for those, the full titanium system is GKA8853T and the three-quarter kit GKA8854T. For the 2016 to 2020 machines, Spark also offers the GKA8817T three-quarter kit that keeps the original collector.
Road Approval
None. Spark lists this system as not approved. Closed course use only — it removes the catalytic converter the motorcycle was type-approved with.
