Öhlins FGR 400 Racing Fork – World Superbike Technology for Track Use

The Öhlins FGR 400 is a purpose-built racing front fork that brings World Superbike-derived suspension technology within reach of serious club and circuit racers. Whether you are chasing lap times at a regional championship or preparing a machine for top-level competition, the FGR 400 delivers a measurable, consistent performance advantage through its combination of ultra-low-friction damping, FKR split-function architecture and a 46 mm inner tube diameter engineered for rigidity at the limit.

Key Features

• TTX twin-tube technology combined with FKR architecture separates compression and rebound damping across individual fork legs, allowing genuinely independent and precise circuit-specific setup.
• Ultra-low-friction, spring-assisted damping system produces exceptionally smooth, controlled fork action even under the harshest braking and cornering loads.
• 46 mm inner tube diameter provides the increased stiffness and chassis stability demanded by high-speed track use and aggressive corner entry.
• Streamlined, weight-optimised construction with Superbike-inspired lower legs reduces unsprung mass and sharpens steering response.
• Integrated top-cap adjusters for compression, rebound and spring preload mean setup changes are quick and straightforward between sessions.
• Supplied as a matched pair — 130 mm of travel, 770 mm overall length, 10.0 N/mm spring rate — giving a ready-to-race, balanced starting point.

Technology in Detail

TTX Twin-Tube Architecture

Öhlins' proven TTX system keeps the damping fluid under constant pressure, eliminating cavitation and delivering a damping curve that remains consistent lap after lap. The result is predictable, repeatable fork behaviour that lets you build confidence and push harder as a session progresses, rather than chasing a moving setup target caused by fade or inconsistency.

FKR Split-Function Damping

FKR technology assigns compression damping to one leg and rebound damping to the other. This physical separation removes the interaction between the two circuits that compromises conventional fork designs, so every click of adjustment has a clean, linear effect. On circuit, that translates directly to the ability to dial in exactly the balance you need for a specific corner type, track surface or riding style — without unintended side effects.

Adjustment and Usability

For a fork carrying this level of engineering, the FGR 400 is notably straightforward to work with day-to-day. All adjustments — compression, rebound and spring preload — are accessible via the top caps, so a mechanic or rider can make meaningful changes quickly without removing the fork. The 10.0 N/mm spring rate (Öhlins spring part number 04744-05, 04744 series) gives a sensible baseline for a wide range of rider weights and circuit styles, and the 130 mm travel figure suits the geometry of modern Superbike-class machinery without compromise.
