DescriptionThe whole story▼
Built exclusively for track use, the Öhlins FKR Cartridge Kit Racing (TTX 25) FKR 108 is a motorsport-grade fork upgrade engineered specifically for the Ducati Panigale 1199 S and 1199 R. As a dedicated racing product, it is not homologated for public road use — every design decision has been made in pursuit of lap-time performance, consistent damping behaviour, and trackside serviceability.
Key Features
- Closed-cartridge TTX system pressurised by a spring rather than gas, eliminating pressure loss through leaks and delivering consistent performance across an entire race session.
- Newly developed piston paired with an 8 mm piston rod reduces internal pressure, producing a faster initial response and a genuinely linear damping curve.
- Linear damping characteristic measurably improves front-end traction and chassis stability under hard braking and through fast direction changes.
- 120 mm stroke cartridge supplied with three spring rates — 9.0, 9.5, and 10.0 N/mm — allowing precise setup for rider weight, tyre compound, and circuit characteristics.
- Simpler architecture than conventional gas-pressure systems makes trackside adjustment and workshop servicing significantly more straightforward.
- Designed for the Öhlins FG 925 fork unit fitted to the Panigale 1199 S/R, ensuring dimensional accuracy and optimal function.
TTX Technology and Closed-System Design
Traditional cartridge systems rely on gas pressure to keep the damping fluid aerated and responsive. Öhlins' TTX approach replaces that gas charge with a preloaded spring inside a sealed cartridge. The result is an architecture that cannot lose pressure through micro-leaks — a failure mode that can degrade conventional systems progressively over a race weekend without the rider ever noticing. With the TTX 25 cartridge, the damping force remains exactly where it was set, lap after lap.
The 8 mm piston rod, combined with the newly developed TTX piston, lowers working pressure throughout the stroke. Lower pressure means the fork responds more quickly to small inputs — the kind of surface irregularities and subtle chassis movements that determine how confidently a rider can carry corner speed. The linear output of the system also makes suspension tuning more predictable: a change in compression or rebound adjustment produces a proportional, readable change in feel rather than the non-linear response that can frustrate setup work with simpler cartridges.
Track Use and Professional Installation
The FKR 108 is a motorsport component. It carries no road-use homologation and must only be used on closed racing circuits. Installation requires dedicated Öhlins special tools and a working knowledge of high-performance fork service procedures. Öhlins strongly recommends that fitting is carried out by an authorised Öhlins service workshop. An installation manual is included in the package to support qualified technicians.
