Öhlins FKR Cartridge Kit Racing TTX 25 FKR 115 – Ducati Panigale 959 (2016–2019)

Engineered exclusively for the track, the Öhlins FKR Cartridge Kit Racing (TTX 25) FKR 115 transforms the front-end behaviour of the Ducati Panigale 959 into something measurably sharper and more consistent. Whether you are chasing lap times or dialling in corner-entry confidence, this cartridge system delivers the kind of all-day comfort under sustained track stress that lets you focus entirely on riding, not on fighting your suspension.

Key Features

• TTX technology uses a spring-vacuum system that guarantees even damping performance with zero risk of pressure loss, even over a long track day.
• Newly developed 8 mm piston rod delivers faster response and a linear damping characteristic that makes fine-tuning predictable and repeatable.
• Supplied with three spring rates — 9.5, 10.0 and 10.5 N/mm — so you can match the setup to your weight, riding style and circuit demands from the outset.
• 120 mm stroke engineered to suit the Ducati Panigale 959 chassis geometry precisely, preserving original handling balance while raising the ceiling of performance.
• Spring series 04744 for compatibility with the full Öhlins spring range, keeping future upgrades straightforward.
• Professional-grade race component: designed, built and validated for circuit use where standard suspension simply cannot keep pace.

TTX Technology and Damping Precision

The TTX (Twin Tube X) cartridge design is the architecture that underpins Öhlins' top-level race products. By separating compression and rebound functions within a twin-tube layout and coupling that with the spring-vacuum oil management system, the FKR 115 maintains damping consistency from the very first corner of a session to the last. There is no cavitation, no fade and no unpredictable mid-corner variation — only the response you set on the adjuster.

The 8 mm piston rod is a meaningful engineering step. A larger rod diameter increases the effective oil-displacement area and reduces the hysteresis in damping force generation. The practical result is a fork that tracks surface irregularities with greater fidelity and gives the front tyre a more consistent contact patch load — directly translating into traction and confidence under braking.

Spring Selection and Setup Flexibility

Arriving with springs rated at 9.5, 10.0 and 10.5 N/mm, the FKR 115 kit acknowledges that no two riders share exactly the same setup requirements. The 04744-series springs are matched to the cartridge's internal geometry and can be swapped quickly at the circuit as conditions or rider feedback demand. This breadth of included spring rates means you are not committing to a single setup before you have turned a wheel in anger.

Fitment and Compatibility

The Öhlins FKR 115 cartridge kit is designed and validated to fit the following motorcycle:

• Ducati Panigale 959 (2016–2019)

Installation by an Öhlins Service Centre is strongly recommended to ensure correct setup, torque settings and initial damping configuration. This product is intended for closed-circuit racing use only. It does not hold a parts certificate (Teilegutachten) and is not approved for use on public roads (StVZO non-compliant). The rider and team are responsible for compliance with all applicable sporting regulations.
