Every component reflects Öhlins' exacting material standards — from the precision-machined 8 mm piston rod to the spring-pressurised sealing system that eliminates pressure drop and guarantees repeatable, fade-free damping lap after lap.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSpring-pressurised closed cartridge system removes air ingress and pressure loss, ensuring a consistent damping curve across the full suspension stroke.\u003c\/li\u003e\n\u003cli\u003eTTX technology combined with a newly developed piston delivers immediate, linear response and eliminates the stick-slip behaviour that blunts corner entry feel.\u003c\/li\u003e\n\u003cli\u003e8 mm piston rod construction provides the rigidity and surface finish precision required for accurate high-speed and low-speed damping adjustment.\u003c\/li\u003e\n\u003cli\u003eThree 04744-series fork springs (9.5, 10.0 and 10.5 N\/mm) included, allowing precise spring-rate matching to rider weight and circuit demands without separate purchases.\u003c\/li\u003e\n\u003cli\u003eDesigned exclusively for forks bearing the Öhlins fork codes FL 940, FL 942 and FL 943 — a direct, no-compromise upgrade path for the factory-specification R1 M suspension unit.\u003c\/li\u003e\n\u003cli\u003eMaintenance-friendly architecture means a trained Öhlins Service Centre can service, re-valve and rebuild the unit to as-new specification.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality and Materials\u003c\/h2\u003e\u003cp\u003eWhere budget cartridge kits rely on cast or pressed components, the FKR 126 uses close-tolerance machined aluminium and hardened steel throughout its internals. The 8 mm piston rod is ground to the surface finish tolerances demanded by the TTX seal pack, ensuring consistent oil film behaviour from cold on the morning warm-up lap through to the final stint of an endurance race. The spring-pressurised closed system is a design philosophy Öhlins has refined across decades of MotoGP and World Superbike programmes: it removes the cavitation risk inherent in conventional open cartridges, which means the damping you set in the paddock is the damping you feel at the apex.\u003c\/p\u003e\u003ch2\u003ePerformance and Track Use\u003c\/h2\u003e\u003cp\u003eThe TTX 25 piston geometry is calibrated for the YZF-R1 M's electronically controlled chassis platform, complementing the factory IMU and semi-active electronics rather than fighting them. The linear damping characteristic means each click of adjustment produces a predictable, proportional change — an essential quality when dialling in setup during a short practice window. Improved traction and directional stability are the tangible results: the front end reports trail information clearly under hard braking and holds its line through long-radius corners where lesser units begin to vague out.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe FKR 126 fits the Yamaha YZF-R1 M RN65 for model years 2020 through 2026. It is compatible only with forks carrying Öhlins fork designations FL 940, FL 942 or FL 943. This is a motorsport product and does not carry a parts certificate (Teilegutachten) for road use in Germany or any other jurisdiction — it is intended solely for closed-circuit competition. Installation by an authorised Öhlins Service Centre is strongly recommended to ensure correct set-up and to protect warranty coverage.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePart number: FKR 126\u003c\/li\u003e\n\u003cli\u003eTechnology: TTX 25 closed cartridge\u003c\/li\u003e\n\u003cli\u003ePiston rod diameter: 8 mm\u003c\/li\u003e\n\u003cli\u003eIncluded springs (04744 series): 9.5 N\/mm, 10.0 N\/mm, 10.5 N\/mm\u003c\/li\u003e\n\u003cli\u003eCompatible forks: Öhlins FL 940 \/ FL 942 \/ FL 943\u003c\/li\u003e\n\u003cli\u003eFitment: Yamaha YZF-R1 M RN65, 2020–2026\u003c\/li\u003e\n\u003cli\u003eUse: track \/ closed-circuit competition only\u003c\/li\u003e\n\u003cli\u003eInstallation manual: included\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Öhlins","offers":[{"title":"Default Title","offer_id":53168756654346,"sku":"FKR 126","price":2326.62,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/FKR_125_d3d4520c-06e7-4507-b65d-cc01000ab899.png?v=1780813705","url":"https:\/\/inter-pace.com\/products\/ohlins-fkr-cartridge-kit-racing-ttx-25-fkr-126","provider":"Inter-Pace","version":"1.0","type":"link"}
