This is a genuine race-specification suspension upgrade, engineered for riders who demand absolute chassis control on both circuit and road.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFive-way adjustability gives you a complete toolkit for dialling in your chassis to any track layout or riding style\u003c\/li\u003e\n\u003cli\u003e32-click compression adjustment and 32-click rebound adjustment for a wide, finely graded damping range\u003c\/li\u003e\n\u003cli\u003e16-click ByPass Valve (BPV) tuning specifically targets low-shaft-speed damping forces — the detail that defines corner-entry confidence\u003c\/li\u003e\n\u003cli\u003eHydraulic preload adjustment lets you alter spring preload without tools, trackside or at the roadside\u003c\/li\u003e\n\u003cli\u003eLength adjustment enables precise geometry changes to optimise steering weight and chassis balance\u003c\/li\u003e\n\u003cli\u003eCNC-machined components throughout for the dimensional accuracy and durability that race use demands\u003c\/li\u003e\n\u003cli\u003eDDS technology with integrated potentiometer mounting points for data-logging compatibility\u003c\/li\u003e\n\u003cli\u003eWide spring-rate selection across the 55-155 series to match rider weight and circuit demands\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eRace-Proven DDS Technology\u003c\/h2\u003e\u003cp\u003eK-Tech's Damper Design System (DDS) is the architecture behind some of the most successful suspension units in British and international racing. The DDS Pro takes that platform further, pairing the core DDS damping circuit with the ByPass Valve — a secondary low-speed circuit that lets you tune initial stroke sensitivity independently of the main compression stack. The result is a shock that can be soft enough to find traction on a bumpy infield section yet firm enough to resist dive under hard braking on the same lap.\u003c\/p\u003e\u003cp\u003eThe addition of potentiometer mounting points means the DDS Pro integrates cleanly with modern data-acquisition systems, allowing engineers and self-coaching riders alike to correlate chassis data with lap-time improvements.\u003c\/p\u003e\u003ch2\u003eBuild Quality\u003c\/h2\u003e\u003cp\u003eEvery major component is CNC-machined to race tolerances. The 35 mm RCU body and 12 mm shaft are sized for the ZX-4RR's packaging constraints while maintaining the structural rigidity needed under repeated high-load inputs. Both upper and lower mounts use an eye configuration — upper eye 30 mm wide with a 10 mm bolt, lower eye 39 mm wide with a 10 mm bolt — ensuring a direct, rattle-free fit to the factory chassis points.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis shock is purpose-built for the Kawasaki ZX-4RR, covering model years 2023, 2024, 2025, and 2026. It is a direct replacement for the factory rear shock with no frame modifications required. Professional installation by an authorised K-Tech Service Centre is strongly recommended; specialist tooling and suspension expertise are required to realise the unit's full performance potential safely.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring series\u003c\/td\u003e\n\u003ctd\u003e55-155\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOverall length\u003c\/td\u003e\n\u003ctd\u003e310 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStroke\u003c\/td\u003e\n\u003ctd\u003e55 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUpper mount\u003c\/td\u003e\n\u003ctd\u003eEye | width 30 mm | bolt diameter 10 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLower mount\u003c\/td\u003e\n\u003ctd\u003eEye | width 39 mm | bolt diameter 10 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRCU body diameter\u003c\/td\u003e\n\u003ctd\u003e35 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRCU shaft diameter\u003c\/td\u003e\n\u003ctd\u003e12 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRCU length adjustment range\u003c\/td\u003e\n\u003ctd\u003e5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompression adjustment\u003c\/td\u003e\n\u003ctd\u003e32 clicks (recommended setting: 12)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRebound adjustment\u003c\/td\u003e\n\u003ctd\u003e32 clicks (recommended setting: 12)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBPV adjustment\u003c\/td\u003e\n\u003ctd\u003e16 clicks (recommended setting: 8)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHydraulic preload (recommended)\u003c\/td\u003e\n\u003ctd\u003e12 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart number\u003c\/td\u003e\n\u003ctd\u003e255-023-150-005\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"K-Tech","offers":[{"title":"Default Title","offer_id":53168834248970,"sku":"255-023-150-005","price":1591.81,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/NEW1223.4png.png?v=1780817015","url":"https:\/\/inter-pace.com\/products\/k-tech-dds-pro-rear-shock-absorber-kawasaki-zx","provider":"Inter-Pace","version":"1.0","type":"link"}
