Öhlins FKR Cartridge Kit Racing TTX 25 FKR 122 – BMW S1000RR K67 (2019–2026)

Engineered exclusively for track and competition use, the Öhlins FKR Cartridge Kit Racing TTX 25 FKR 122 transforms the front-end behaviour of the BMW S1000RR K67 (2019–2026) into something a privateer racer or serious track-day rider can genuinely exploit. This is not a road-biased upgrade — it is a dedicated racing cartridge system built around the pressure-fed, closed-circuit TTX technology that Öhlins developed at the highest levels of motorsport.

Key Features

• Pressure-fed closed system eliminates the risk of pressure loss, delivering consistent, repeatable damping lap after lap regardless of conditions or heat build-up.
• TTX technology combined with a newly developed piston and an 8 mm piston rod produces rapid initial response and a linear damping characteristic that rewards precise, aggressive riding.
• Extensive tuning options allow the suspension to be tailored precisely to track surface, tyre compound, and individual riding style — essential for shaving tenths.
• Improved traction and ride stability under hard braking and through high-speed corners, giving the S1000RR K67 a more planted, confidence-inspiring front end.
• Maintenance-friendly construction keeps service intervals practical even in a demanding race environment.
• Springs included in the kit — 04744-series and 08790-series, available in 9.0, 9.5, and 10.0 N/mm rates — meaning the correct setup is ready without additional sourcing.

TTX Technology and Racing Construction

The TTX cartridge principle has proven itself across World Superbike, MotoGP support classes, and top-level circuit racing for years. Öhlins brought that architecture directly into the FKR 122: the pressurised closed circuit keeps the damping fluid in a controlled, gas-separated environment so cavitation is eliminated and the fork behaves identically on the first lap of a session as it does on the last. The newly specified piston, working alongside the stiff 8 mm piston rod, responds to small inputs without sacrificing authority under the enormous braking forces the S1000RR K67 generates. The result is a front end that communicates honestly and allows the rider to carry more speed into corners with genuine confidence.

Setup and Tuning

Three spring rates — 9.0, 9.5, and 10.0 — ship with the kit, covering a wide range of rider weights and track configurations without the need for separate spring orders. The system's architecture supports further tuning through oil viscosity, spring preload, and compression and rebound damping adjustment, giving a technician or experienced rider the scope to dial in precisely the balance they need. Öhlins recommends installation by an authorised Öhlins Service Centre for optimum results, and a fitment guide is included in the box.
