On a retro roadster that is a startling pair of numbers — the Z900RS looks like a 1970s motorcycle, and Kawasaki's standard header assembly weighs like one too: 9.6 kg of steel with the catalytic converter inside.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e3.2 kg against the standard 9.6 kg: 6.4 kg and 66.7 per cent less\u003c\/li\u003e\n\u003cli\u003e10.8 PS more at 8,600 rpm, peak output rising from 101.6 to 112.3 PS\u003c\/li\u003e\n\u003cli\u003e6.5 Nm more at 2,900 rpm — the gain runs through the whole rev range\u003c\/li\u003e\n\u003cli\u003eBuilt from perfectly welded high-grade stainless steel tubes\u003c\/li\u003e\n\u003cli\u003eCompatible with the Kawasaki centre stand\u003c\/li\u003e\n\u003cli\u003eTurns the Slip-On Line into a full system\u003c\/li\u003e\n\u003cli\u003eNo road approval — circuit use only\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eGain at Both Ends of the Range\u003c\/h2\u003e\n\u003cp\u003eMost headers find their power high up and give something away at the bottom. This one adds 6.5 Nm at 2,900 rpm and 10.8 PS at 8,600 — Akrapovic states the increase runs through the entire rev range, and the two measured points bear that out.\u003c\/p\u003e\n\u003cp\u003eOn a Z900RS that matters. It is a motorcycle ridden at moderate revs on back roads more than it is revved out, and a header that only worked above eight thousand would be the wrong part for it.\u003c\/p\u003e\n\u003ch2\u003eWhere 6.4 Kilograms Were Hiding\u003c\/h2\u003e\n\u003cp\u003eKawasaki hides the Z900RS's exhaust plumbing well: the visible silencer is compact and the rest disappears under the engine. What is under there is 9.6 kg of double-skinned steel with a large catalytic converter, sized for Euro noise and emissions limits on a 948 cc four.\u003c\/p\u003e\n\u003cp\u003eRemoving two thirds of that changes the motorcycle's centre of gravity as well as its total mass, because all of it sits low and central.\u003c\/p\u003e\n\u003ch2\u003eThe Centre Stand Stays\u003c\/h2\u003e\n\u003cp\u003eKawasaki's centre stand is a common accessory on the Z900RS, and headers routinely foul it. This one does not — Akrapovic states the system is compatible, so chain maintenance stays as easy as it was.\u003c\/p\u003e\n\u003ch2\u003eWhat You Need Alongside It\u003c\/h2\u003e\n\u003cp\u003eThis header is not a complete exhaust. It converts an Akrapovic Slip-On Line into a full system — for the Z900RS that is S-K9SO5-HBAVTBL for the 2018 to 2025 machines. Akrapovic also notes that special mapping is needed for the best performance, throttle response and durability.\u003c\/p\u003e\n\u003ch2\u003eNot the Same Part as the Z900\u003c\/h2\u003e\n\u003cp\u003eThe Z900RS and the Z900 share a 948 cc engine but not an exhaust. Kawasaki routes the RS differently to suit the retro bodywork and the twin-shock look, so the header for one will not go on the other.\u003c\/p\u003e\n\u003cp\u003eIf you are shopping by engine capacity rather than by model name, this is where it goes wrong. Check the model, not the displacement.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eE-K9R3 covers the Kawasaki Z900RS and Z900RS SE from model year 2018 through 2025.
