Every component has been built to the exacting standards Öhlins maintains for professional motorsport, delivering a level of damping precision and mechanical refinement that simply cannot be matched by conventional gas-pressure cartridge systems.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eTTX technology: a closed, spring-pressurised system that maintains consistent damping performance and eliminates the risk of pressure loss through seal leakage\u003c\/li\u003e\n\u003cli\u003eReduced internal pressure via a new piston and 8 mm piston rod — resulting in faster initial response and a genuinely linear damping curve\u003c\/li\u003e\n\u003cli\u003eGreater fine-tuning range across compression and rebound compared to traditional open-bath cartridges\u003c\/li\u003e\n\u003cli\u003eThree fork spring rates included (9.0, 9.5 and 10.0 N\/mm from the 04744 series) to match the kit precisely to rider weight\u003c\/li\u003e\n\u003cli\u003eCompatible exclusively with forks fitted with Öhlins FL 910 or FL 926 internals — ensuring OEM-quality fitment integrity\u003c\/li\u003e\n\u003cli\u003eDeveloped from World Superbike and Grand Prix machinery: the same engineering DNA, adapted for high-end club and professional racing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eEngineering \u0026amp; Build Quality\u003c\/h2\u003e\u003cp\u003eThe FKR system's defining characteristic is its closed, spring-pressurised architecture. Where conventional gas-pressure cartridges rely on a separate nitrogen charge to suppress cavitation, the TTX design uses a controlled spring preload on the oil column. The result is a system that stays balanced across temperature cycles and extended track sessions without the degradation associated with gas pressure loss. The precision-machined 8 mm piston rod works in concert with the new piston design to reduce stiction at the initiation of damper stroke — the phase where many competing systems feel vague or wooden — giving the rider immediate, predictable feedback from the first millimetre of wheel travel.\u003c\/p\u003e\u003ch2\u003eTrack Performance\u003c\/h2\u003e\u003cp\u003eOn the Honda CBR 1000 RR SP SC77, where the standard Öhlins fork already sets a high baseline, the FKR 109 cartridge kit elevates front-end behaviour to an entirely different level. The linear damping characteristic means adjustments made at the clicker are truly proportional — one click of compression or rebound produces the same effect whether the fork is moving slowly through a chicane or working hard under heavy braking. This consistency translates directly into improved traction on corner entry and greater confidence to carry speed deep into braking zones. Fork spring selection from the included 04744-series springs (9.0, 9.5 and 10.0 N\/mm) allows the setup to be optimised for the individual rider's weight, as detailed in the installation manual.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis kit is designed exclusively for the Honda CBR 1000 RR SP in SC77 specification, covering model years 2017 to 2019. Compatibility is further restricted to machines fitted with Öhlins fork legs FL 910 or FL 926. Installation requires specialist tools and fork oil, neither of which is included; fitting by a qualified suspension workshop is strongly recommended. This product carries no road-use approval and is not permitted for use on public roads under German StVZO regulations or equivalent legislation elsewhere.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePart number: FKR 109\u003c\/li\u003e\n\u003cli\u003eTechnology: Öhlins TTX 25 (closed, spring-pressurised cartridge system)\u003c\/li\u003e\n\u003cli\u003ePiston rod diameter: 8 mm\u003c\/li\u003e\n\u003cli\u003eSpring series: 04744\u003c\/li\u003e\n\u003cli\u003eIncluded spring rates: 9.0 N\/mm, 9.5 N\/mm, 10.0 N\/mm\u003c\/li\u003e\n\u003cli\u003eCompatible forks: Öhlins FL 910, FL 926\u003c\/li\u003e\n\u003cli\u003eFitment: Honda CBR 1000 RR SP SC77 (2017–2019)\u003c\/li\u003e\n\u003cli\u003eIntended use: race track only — not approved for road use\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eRace Use Only.\u003c\/p\u003e","brand":"Öhlins","offers":[{"title":"Default Title","offer_id":53168695902474,"sku":"FKR 109","price":2326.62,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/FKR_125_385ae0b1-eeb0-4b48-aeb4-d8a16e906461.png?v=1780811250","url":"https:\/\/inter-pace.com\/products\/ohlins-ttx-25-cartridge-kit-racing-fkr-109","provider":"Inter-Pace","version":"1.0","type":"link"}
