Öhlins FKR Cartridge Kit Racing TTX 25 FKR 105 – Suzuki GSX-R 1000 R (2017–2023)

Engineered for riders who refuse to compromise, the Öhlins FKR Cartridge Kit Racing TTX 25 FKR 105 brings genuine race-grade front suspension to the Suzuki GSX-R 1000 R. Built around Öhlins' latest TTX technology, this cartridge kit replaces the factory internals with a precision-machined system that delivers consistent, repeatable damping performance every time you brake into a corner.

Key Features

• TTX technology with a negative spring pressure system eliminates the risk of pressure loss associated with gas-pressure units, ensuring damping performance never degrades across a race distance.
• Newly developed 8 mm piston rod reduces internal friction and lowers internal pressure, delivering faster initial response and measurably improved front-end stability under hard braking.
• Linear damping characteristic gives a predictable, tuneable feel — precisely what is needed when adjusting setup between sessions at the track.
• Extended tuning range allows fine adjustment of compression and rebound to suit individual riding styles and changing track conditions.
• Supplied with three spring rates — 9.0, 9.5 and 10.0 N/mm (04744-series springs) — covering a wide spread of rider weights and circuit types straight from the box.
• Simpler internal architecture compared to conventional gas-charged cartridges means servicing is more straightforward at an authorised Öhlins Service Centre.

Build Quality and Materials

The FKR 105 is a product of Öhlins' decades of motorsport development. The cartridge bodies are machined to exacting tolerances, and every internal component is selected for durability under the sustained thermal and mechanical loads of competitive track riding. The 8 mm piston rod is a key engineering detail: its reduced diameter and surface finish lower stiction to a minimum, allowing the fork to respond to small track imperfections that a heavier rod would simply transmit to the rider's hands. The result is a front end that feels alive and communicative rather than vague or artificially stiff.

Track Performance

On circuit, the TTX cartridge system's linear damping characteristic transforms the GSX-R 1000 R's front-end feedback. Where the factory Showa BFF fork can feel overwhelmed under repeated heavy braking, the Öhlins unit maintains consistent damping force throughout a stint. The ability to run three distinct spring rates without purchasing additional hardware means setup changes can be made quickly in the paddock without waiting for parts. Combined with the extended high-speed and low-speed adjustment range, the FKR 105 puts genuine professional-level suspension tuning within reach for club and championship competitors alike.

Fitment and Compatibility

The Öhlins FKR 105 is designed exclusively for the Suzuki GSX-R 1000 R equipped with the Showa BFF (Balance Free Front) fork, covering model years 2017 to 2022. It is not compatible with GSX-R 1000 R variants that do not feature the Showa BFF fork, nor with any standard GSX-R 1000 model. This kit is intended for track use only and carries no type approval for use on public roads in Germany (StVZO) or equivalent road-use legislation in other markets. Installation should be carried out by an authorised Öhlins Service Centre; a full fitting guide is included in the package.
