Öhlins FKR Cartridge Kit Racing TTX 25 FKR 108 – Ducati Panigale 1299 S (2015-2018)

When race results depend on what your fork does at corner entry, the Öhlins FKR Cartridge Kit Racing TTX 25 FKR 108 is the answer. Purpose-engineered for the Ducati Panigale 1299 S (2015-2018) equipped with the Öhlins FG 925 fork, this cartridge kit replaces the stock internals with a closed, spring-pressurised FKR system that delivers linear damping characteristics tuned exclusively for track use.

Key Features

• Closed FKR system pressurised by spring rather than gas — eliminates pressure loss from seal leakage, ensuring consistent damping performance across every session and throughout the entire race day.
• TTX technology paired with a newly developed piston and an 8 mm piston rod reduces internal pressure, producing faster, more precise damping response compared to conventional gas-pressure systems.
• Linear damping curve matched to track demands delivers measurably improved traction and front-end stability under hard braking and through high-speed corners.
• Easier to service than standard gas-charged cartridges — the spring-pressurised closed circuit is inherently more maintenance-friendly and more reliable over extended use.
• Expanded tuning range: the TTX architecture opens up more adjustment possibilities, letting engineers dial in compression and rebound to suit tyre compound, circuit, and rider preference.
• 120 mm stroke engineered to the Panigale 1299 S suspension travel, maximising the usable damping window on track.

TTX Technology Explained

Öhlins TTX (Twin Tube X) technology works by keeping the damping piston and the compression valve in a twin-tube layout that separates oil flow paths. In the FKR context this means the 8 mm piston rod generates lower rod-displacement volume changes, reducing cavitation risk and allowing the system to operate at lower internal pressures. The result is a cartridge that responds to even subtle chassis inputs — small bumps mid-corner, minor kerb strikes — rather than only reacting to large suspension events.

FKR System Reliability on the Racetrack

Traditional gas-pressurised fork cartridges rely on a pressurised gas chamber to separate oil from air and to keep the damping circuit primed. Any seal degradation bleeds pressure, compromising damping consistency. The FKR system uses a mechanical spring to pressurise the closed oil circuit instead. There is no gas charge to lose, which means the cartridge performs identically at the start of a qualifying lap as it does at the end of a 20-lap race distance. For riders competing in timed sessions where setup repeatability is critical, this characteristic is a genuine advantage.

Fitment & Compatibility

• Ducati Panigale 1299 S (2015-2018) — for models fitted with the Öhlins FG 925 front fork only.
• Racing use only — this is a motorsport product and is not homologated for use on public roads.
• Installation requires specialist tools and technical knowledge. Öhlins recommends fitting by an authorised Öhlins service workshop.
