Öhlins FKR Cartridge Kit Racing TTX 25 FKR 115 – Ducati Panigale 899 (2013–2016)

Engineered exclusively for track use on the Ducati Panigale 899, the Öhlins FKR Cartridge Kit Racing TTX 25 FKR 115 transforms your fork's damping character from the inside out. By replacing the standard internals with a purpose-built TTX cartridge system, it delivers the kind of linear, confidence-inspiring response that lets you carry more corner speed and load the front tyre consistently — lap after lap, all day at the circuit.

Key Features

• TTX spring-under-vacuum technology eliminates the pressure spikes inherent in conventional gas-pressurised cartridge systems, giving the fork a more supple, immediate response off the top of the stroke.
• Newly developed 8 mm piston rod reduces internal friction and operating pressure, improving small-bump sensitivity and overall damping linearity.
• 120 mm travel keeps suspension geometry accurate through deep braking and full compression, critical for consistent corner entry on a high-performance Superbike.
• Three spring rates included — 9.5, 10.0, and 10.5 N/mm — so you can dial the setup to your body weight and riding style without additional expense.
• 04744-series springs are matched to the TTX piston specification for optimised progression and fade-free performance across a full race day.
• Broad adjustment range for compression and rebound lets you fine-tune the Panigale's front end precisely to circuit conditions and tyre compound.

TTX Technology — Why It Matters on Track

The TTX (Twin Tube X-Over) cartridge architecture separates the compression and rebound circuits more effectively than a conventional monotube design. The result is a damping curve that stays consistent regardless of oil temperature — a genuine advantage during long stints or when ambient temperatures climb. Combined with the lower internal pressure enabled by the 8 mm piston rod, the fork tracks surface imperfections without sacrificing the rigidity you need under hard braking into a chicane.

Installation must be carried out by an authorised Öhlins Service Centre. A full fitting guide is supplied with the kit. This product is designed for closed-circuit racing only and carries no approval for use on public roads in Germany (not StVZO-compliant).
