The Z H2 is the heaviest bike Kawasaki builds around its supercharged four, and the standard header assembly under the engine accounts for 6.7 kg of that.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eHeader assembly down to 4.0 kg — Kawasaki's own weighs 6.7\u003c\/li\u003e\n\u003cli\u003eOutput climbs to 188.8 PS, measured 10.9 above standard at 11,200 rpm\u003c\/li\u003e\n\u003cli\u003eTorque up by 6.2 Nm, measured at 6,800 rpm\u003c\/li\u003e\n\u003cli\u003eBuilt entirely from Akrapovic's finest stainless steel\u003c\/li\u003e\n\u003cli\u003eCompletes an Akrapovic slip-on into a full racing system\u003c\/li\u003e\n\u003cli\u003eA fresh ECU map is recommended, not optional in practice\u003c\/li\u003e\n\u003cli\u003eNo road approval — circuit use only\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhich Kawasaki Is Yours\u003c\/h2\u003e\n\u003cp\u003eKawasaki builds three motorcycles around the supercharged 998 cc four: the faired H2, the H2 SX sports tourer and the naked Z H2. They are not interchangeable, and this header is for the Z H2 alone.\u003c\/p\u003e\n\u003cp\u003eThe Z H2 SE, with Brembo Stylema brakes and Showa Skyhook electronic suspension, shares the engine and the exhaust route and takes the same part.\u003c\/p\u003e\n\u003ch2\u003eWhy the Remap Is Not Optional Advice\u003c\/h2\u003e\n\u003cp\u003eAkrapovic recommends remapping for performance, throttle response and durability. On a forced-induction engine, that third word is the one to read twice: a lean mixture under boost damages hardware in a way it does not on a naturally aspirated motor.\u003c\/p\u003e\n\u003cp\u003eTreat the dyno session as part of the purchase price rather than as something to weigh up afterwards.\u003c\/p\u003e\n\u003ch2\u003eNinety Minutes, and Why It Is Not Longer\u003c\/h2\u003e\n\u003cp\u003eThe supercharger sits behind the cylinders and drives off the crankshaft, so it is not in the way of the exhaust ports. The header comes out from below with the belly section removed — an hour and a half of workshop time, which is short for a header on a bike this densely packed.\u003c\/p\u003e\n\u003ch2\u003eA Used Motorcycle Now\u003c\/h2\u003e\n\u003cp\u003eKawasaki introduced the Z H2 in 2020 and revised it for Euro 5+ in 2024. Machines from the first four years are used bikes today, past their steepest depreciation, which changes the calculation on a track-only part: there is less to lose and the motorcycle is more likely to see a circuit.\u003c\/p\u003e\n\u003ch2\u003eWhat the Slip-On Cannot Do Alone\u003c\/h2\u003e\n\u003cp\u003eA slip-on replaces the silencer and leaves the catalytic converter and the header assembly in place. On a Z H2 that means the largest restriction in the system stays exactly where it was, which is why the slip-on's own figures are modest and the header's are not.\u003c\/p\u003e\n\u003cp\u003eFitted together the two form a complete exhaust from the cylinder head back, and that is the combination Akrapovic measured.\u003c\/p\u003e\n\u003ch2\u003eStainless Rather Than Titanium\u003c\/h2\u003e\n\u003cp\u003eAkrapovic uses steel for this header and not titanium, which on a part that saves 2.7 kg looks like a missed opportunity until you consider where it lives. A header sits directly under the engine, in the path of every stone the front wheel throws, and steel takes that.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eE-K10R6 covers the Kawasaki Z H2 and Z H2 SE from 2020 through 2023. Machines from 2024 take E-K10R8, which is a separate part — Kawasaki changed the lambda sensor arrangement for Euro 5+. It requires an Akrapovic slip-on to complete the system.\u003c\/p\u003e\n\u003ch2\u003eRoad Approval\u003c\/h2\u003e\n\u003cp\u003eNone.
