This one weighs 1.84 kg. That is 53.2 % gone — more than half — and it is the largest single weight saving available on the bike for the money. The Akrapovic Slip-On Line (Carbon) S-K9SO6-HZC does it with a hand-crafted carbon fibre body and end cap, and it keeps EC and ECE type approval while doing so.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1.84 kg against the standard 3.93 kg: 2.09 kg removed, a 53.2 % reduction at the silencer\u003c\/li\u003e\n\u003cli\u003eCompact shape drawn to suit a naked bike, so the muffler sits tight under the tail instead of hanging past it\u003c\/li\u003e\n\u003cli\u003eHand-crafted carbon fibre body finished with an end cap in the same material\u003c\/li\u003e\n\u003cli\u003e1.2 PS (0.9 kW) more power and 0.8 Nm more torque at 8,150 rpm, gains spread across the range rather than concentrated at one point\u003c\/li\u003e\n\u003cli\u003eEC and ECE type approved, and additionally EPA noise compliant\u003c\/li\u003e\n\u003cli\u003eNoise insert included for circuits with their own decibel limit\u003c\/li\u003e\n\u003cli\u003ePlug-and-play in about 30 minutes, no remapping needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eConstruction and Material Quality\u003c\/h2\u003e\n\u003cp\u003eMore than half the weight of a steel silencer disappears when the outer body is carbon fibre rather than steel, and on the Z900 that difference is unusually large because the standard unit is a heavy double-skinned item built to meet Euro 5 quietly and cheaply. Akrapovic lays the carbon by hand, and the end cap is the same material rather than a machined aluminium ring — a detail that matters on a naked bike, where the silencer is the first thing anyone looks at.\u003c\/p\u003e\n\u003cp\u003eThe shape is shorter and more compact than the standard part. On a machine with no bodywork behind the rider's seat, that changes the visual proportion of the whole rear of the bike.\u003c\/p\u003e\n\u003ch2\u003ePerformance and Sound\u003c\/h2\u003e\n\u003cp\u003eThe measured gains are modest and stated plainly: 111.9 PS becomes 113.0 PS, and torque goes from 92.0 Nm to 92.8 Nm with the peak gain of 0.8 Nm at 8,150 rpm. Akrapovic describes the improvement as spread across the range rather than a single peak, and on a road bike that is the more useful shape of gain.\u003c\/p\u003e\n\u003cp\u003eWhat changes far more than the numbers is the noise. The in-line four gains depth and a hard edge on the overrun that the standard system suppresses entirely, and it remains inside the type-approved window.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eS-K9SO6-HZC is developed for the Kawasaki Z900 from model year 2020 to 2024, including the A2-restricted version, which shares the same exhaust. It is tested on EU-specification machines; fitment and measured performance on non-EU models can differ.\u003c\/p\u003e\n\u003cp\u003eTwo optional parts exist for this bike: a stainless steel header, E-K9R4, and a carbon fibre heat shield, P-HSK9SO1. Both are separate items and neither is needed to fit the slip-on. Fitting the optional header cancels the road approval of the silencer.\u003c\/p\u003e\n\u003ch2\u003eRoad Approval\u003c\/h2\u003e\n\u003cp\u003eEC type approval and ECE type approval, with the certificates supplied and downloadable here. The system is additionally EPA noise compliant. Fitted on its own, without the optional header, the silencer is a legal road part in the European Union.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePart number: S-K9SO6-HZC\u003c\/li\u003e\n\u003cli\u003eEAN: 3831113577557\u003c\/li\u003e\n\u003cli\u003eFitment: Kawasaki Z900 (2020–2024), A2 version included\u003c\/li\u003e\n\u003cli\u003eSystem type: slip-on silencer\u003c\/li\u003e\n\u003cli\u003eBody material: carbon fibre, hand-crafted\u003c\/li\u003e\n\u003cli\u003eEnd cap: carbon fibre\u003c\/li\u003e\n\u003cli\u003eSystem weight: 1.84 kg (stock 3.93 kg, saving 2.09 kg \/ 53.2 %)\u003c\/li\u003e\n\u003cli\u003ePower: 113.0 PS at 9,650 rpm (stock 111.9 PS at 9,700 rpm, gain 1.2 PS \/ 0.9 kW)\u003c\/li\u003e\n\u003cli\u003eTorque: 92.8 Nm (stock 92.0 Nm at 8,100 rpm, gain 0.8 Nm at 8,150 rpm)\u003c\/li\u003e\n\u003cli\u003eNoise insert: included\u003c\/li\u003e\n\u003cli\u003eRemapping: not required\u003c\/li\u003e\n\u003cli\u003eInstallation time: approx. 30 minutes\u003c\/li\u003e\n\u003cli\u003eRoad approval: EC type approval, ECE type approval, EPA noise compliant\u003c\/li\u003e\n\u003cli\u003eCountry of manufacture: Slovenia\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Akrapovic","offers":[{"title":"Default Title","offer_id":53626537345290,"sku":"S-K9SO6-HZC","price":730.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/01.png?v=1788506090","url":"https:\/\/inter-pace.com\/en-us\/products\/akrapovic-slip-on-line-carbon-kawasaki-z900-s-k9so6-hzc","provider":"Inter-Pace","version":"1.0","type":"link"}
