Designed to meet the exacting demands of circuit competition, this closed, spring-pressurised cartridge system delivers consistent, repeatable damping performance lap after lap — with no pressure loss and no compromise on rider safety. Note: this is a motorsport product and is not approved for use on public roads. It does not carry a German parts certificate (Teilegutachten) and must be installed by an authorised Öhlins Service Centre for optimal results.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eClosed, spring-pressurised system eliminates pressure loss and guarantees consistent damping behaviour under sustained race conditions.\u003c\/li\u003e\n\u003cli\u003eAdvanced TTX technology paired with a newly developed piston and 8 mm piston rod delivers fast, precise response and a linear damping characteristic.\u003c\/li\u003e\n\u003cli\u003eLinear damping curve enables precise, fine-grained tuning — improving traction and raising chassis stability exactly where it counts on track.\u003c\/li\u003e\n\u003cli\u003e120 mm stroke gives the fork the travel range needed for full commitment on circuit without sacrificing feedback.\u003c\/li\u003e\n\u003cli\u003eThree spring rates included (9.0, 9.5 and 10.0 N\/mm, 04744-series and 08790-series) so the kit can be dialled in for rider weight and track demands straight from the box.\u003c\/li\u003e\n\u003cli\u003eInstallation guide included; for race-ready setup, Öhlins recommends fitting by an authorised Service Centre.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTTX Technology and Race-Grade Construction\u003c\/h2\u003e\u003cp\u003eThe TTX (Twin Tube Cross-section) cartridge architecture is the cornerstone of Öhlins race suspension engineering. By separating the compression and rebound circuits within a pressurised closed system, TTX removes the cavitation and aeration that compromise conventional open cartridges under hard braking and aggressive direction changes. The result is a fork that maintains its calibrated character throughout a full race stint, not just the opening laps.\u003c\/p\u003e\u003cp\u003eThe newly developed piston geometry, working in concert with the 8 mm piston rod, sharpens initial response — meaning the fork reacts the moment the wheel meets a kerb or a braking bump, rather than exhibiting the brief lag that can unsettle a rider's confidence at the limit. For pilots on the BMW M1000RR K66, this translates directly into earlier, more confident braking markers and cleaner drive out of slow corners.\u003c\/p\u003e\u003ch2\u003eTuning Flexibility and Setup\u003c\/h2\u003e\u003cp\u003eThree spring rates — 9.0, 9.5 and 10.0 N\/mm — are included, drawn from the 04744-series and 08790-series Öhlins spring ranges. This selection covers a broad spread of rider weights and circuit preferences without requiring additional expenditure before the first shakedown session. Combined with the TTX damping adjusters, the FKR 122 gives a suspension engineer the tools to build a bespoke fork setup for any track configuration, from the high-speed sweepers of Monza to the technical stops of the Nürburgring GP circuit.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Öhlins FKR 122 cartridge kit is designed and validated specifically for the following fitment:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBMW M1000RR K66 — model years 2021, 2022, 2023, 2024, 2025, 2026\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eThis is a motorsport product.
