Spring 01093-29 is what ships with the damper; harder and softer rates are available. Öhlins fits a 90 N\/mm spring to this number; riders far from average weight should expect to change it. Öhlins gives 307,5 +4\/-2 mm of length adjustment, which is the cleanest way to alter the ZX-4 RR's attitude. The two adjusters do genuinely separate jobs, which is what makes methodical setup possible. The adjuster range is usable end to end rather than only around the middle.\u003c\/p\u003e\u003ch2\u003eMaterials and Manufacture\u003c\/h2\u003e\u003cp\u003eÖhlins machines its own critical components instead of buying them in, and the tolerances are where the money goes. The eyelets carry spherical bearings rather than rubber bushes, so the damper is not fighting its own mounting. Öhlins sets a baseline for each part number on the machine it was developed on, so it works before anything is adjusted.\u003c\/p\u003e\u003ch2\u003eAbout the STX 46 Supersport Range\u003c\/h2\u003e\u003cp\u003eLength adjustment lets rear ride height be raised to quicken the steering. The 46 mm piston and monotube body carry over from the Street version; the shim stack does not. Öhlins sets this specification for machines ridden hard on good surfaces.\u003c\/p\u003e\u003ch2\u003eSetting It Up for the ZX-4 RR\u003c\/h2\u003e\u003cp\u003eOn a supersport machine, front-end feel under braking is what the rider trusts, and damping is what provides it.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis listing covers Öhlins part number KA 401 for the Kawasaki ZX-4 RR, 2024–2025. 2 machines in the range take this number, the Kawasaki ZX-4 RR among them.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eRoad approval: ABE (Germany). The unit is covered by a German ABE for the Kawasaki ZX-4 RR, so no individual inspection or entry in the vehicle documents is required. The approval document ships with the product.\u003c\/p\u003e\u003ch2\u003eFitting and Setup Service\u003c\/h2\u003e\u003cp\u003eÖhlins suspension rewards careful fitting. We recommend having the work done by an authorised Öhlins service centre — and we are one ourselves: we fit, service and set up Öhlins components in house. If you would like us to handle the installation, just ask and we will quote it with the order.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cem\u003eBrand:\u003c\/em\u003e Öhlins\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePart Number:\u003c\/em\u003e KA 401\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eFitment:\u003c\/em\u003e Kawasaki ZX-4 RR (2024–2025)\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eRoad Approval:\u003c\/em\u003e ABE (Germany)\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eMounting Position:\u003c\/em\u003e Rear\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eLength:\u003c\/em\u003e 307,5 +4\/-2 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eStroke:\u003c\/em\u003e 49,5 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eSpring Rate:\u003c\/em\u003e 90 N\/mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003ePiston Diameter:\u003c\/em\u003e 36 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cem\u003eSpring Part Number:\u003c\/em\u003e 01093-29\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Öhlins","offers":[{"title":"Default Title","offer_id":53639720370442,"sku":"KA 401","price":1365.01,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/a_c_s46pr1c1ls_ka_401_08_17d9a709-95e4-4c43-90f3-8e1645ebe89d.png?v=1789655426","url":"https:\/\/inter-pace.com\/products\/ohlins-stx-46-supersport-shock-absorber-kawasaki-zx-4-rr-2024-2025-ka-401","provider":"Inter-Pace","version":"1.0","type":"link"}
