Spark's titanium racing collector for the Z900 weighs 2.2 kg where the standard one weighs 7.8 — the largest single weight reduction available on this motorcycle, and a limited edition rather than a catalogue staple.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFull titanium racing collector for the Kawasaki Z900, 2025 to 2026.\u003c\/li\u003e\n\u003cli\u003e2.2 kg against 7.8 kg standard — 5.6 kg saved.\u003c\/li\u003e\n\u003cli\u003eLimited edition, per Spark.\u003c\/li\u003e\n\u003cli\u003eDesigned to pair with Spark's Euro5+ slip-ons.\u003c\/li\u003e\n\u003cli\u003eSupplied without a silencer.\u003c\/li\u003e\n\u003cli\u003eRacing part — no catalytic converter, no certificate.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere Five and a Half Kilos Live\u003c\/h2\u003e\u003cp\u003eOn an inline four the collector is the heaviest single component of the exhaust, and on a Euro5+ machine it is heavier still because the catalytic converter sits inside it. Kawasaki's standard unit weighs 7.8 kg.\u003c\/p\u003e\u003cp\u003eReplacing it with 2.2 kg of titanium takes more than five kilos off a motorcycle that weighs a little over two hundred — and takes it from low and forward, under the engine, where mass has the strongest effect on how a bike changes direction. There is no other single part on a Z900 that does anything comparable.\u003c\/p\u003e\u003ch2\u003eLimited, and What That Means\u003c\/h2\u003e\u003cp\u003eSpark describes this as a limited edition titanium racing manifold. On a part like this that is not marketing language: full titanium collectors are hand-welded, and the tooling and labour behind one do not scale the way a stainless production part does.\u003c\/p\u003e\u003cp\u003eThe practical consequence is availability rather than exclusivity. If this collector is part of the plan for the motorcycle, it is worth ordering while it is listed rather than assuming it will be there next season.\u003c\/p\u003e\u003ch2\u003eWhat It Needs Behind It\u003c\/h2\u003e\u003cp\u003eThe collector is sold without a silencer. Spark's Euro5+ slip-ons for the same machine — the Konix Evo GKA0907TOM and GKA0907DOM, and the Grid-O GKA0908TOM — are the intended partners, and each comes with a carbon fibre heat shield for the pipe.\u003c\/p\u003e\u003cp\u003eNote what the combination does to the paperwork. The slip-ons are homologated on their own; this collector is not, and fitting it removes the catalytic converter. A Z900 with both is a racing motorcycle regardless of what the silencer's certificate says.\u003c\/p\u003e\u003ch2\u003eRacing DNA, Spark's Words\u003c\/h2\u003e\u003cp\u003eSpark presents this collector as the companion to its Euro5+ slip-on range — an experience with, in the company's phrase, pure racing DNA. That is marketing language, but the part behind it is not: a hand-welded full titanium four-into-one for a road naked bike is an unusual thing to build.\u003c\/p\u003e\u003cp\u003eIt is also the reason the Z900 range reads the way it does. The slip-ons are homologated and sensible; this is the component that turns the same motorcycle into something else entirely.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eKawasaki Z900, 2025 through 2026.
