DescriptionThe whole story▼
The Öhlins FKR 103 Cartridge Kit Racing with TTX 25 technology represents the pinnacle of Scandinavian suspension engineering — a purpose-built racing cartridge system designed exclusively for the Yamaha YZF-R1 M (RN32 & RN49, 2015–2019) fitted with the Öhlins FL 912 fork. Where conventional gas-pressure systems are prone to pressure loss under sustained track abuse, the FKR system's pressurised spring design delivers unwavering, consistent damping performance from the first lap to the last.
Key Features
- TTX (Twin Tube X-over) technology eliminates the pressure-loss vulnerabilities inherent to gas-pressure cartridge systems, ensuring repeatable performance across an entire race stint.
- Revised piston architecture paired with an 8 mm piston rod reduces internal pressure peaks, producing faster reaction times and a noticeably more responsive initial stroke.
- Linear damping characteristic provides a broad, accessible tuning range — dial in traction and stability to suit circuit, tyre and rider preference without compromise.
- Supplied with three fork spring rates (9.5, 10.0 and 10.5 N/mm from the 04744 series), allowing precise spring selection to match rider weight and riding style.
- Engineered specifically for the Yamaha YZF-R1 M RN32 & RN49 platform — a direct, application-specific fit requiring no adaptation.
Performance & Design Heritage
Öhlins has built its reputation over decades of top-tier motorsport, supplying suspension to MotoGP, World Superbike and Isle of Man TT competitors. The FKR Cartridge Kit Racing carries that lineage directly onto your R1 M. The TTX 25 twin-tube architecture is the same conceptual DNA found in Öhlins' elite factory-level dampers: oil flow is managed across both compression and rebound circuits simultaneously, producing a damping curve that feels natural and progressive rather than abrupt.
The decision to use a pressurised spring rather than a conventional gas bladder is a deliberate engineering choice. Pressure integrity is maintained across extreme temperature cycles — exactly the conditions generated inside a closed-cartridge fork after repeated heavy braking zones and high-speed compressions. The result is a fork that feels identical at the end of a race as it did at the beginning of the warm-up lap.
Track Application & Tuning
The linear damping characteristic of the FKR 103 is particularly well suited to riders who work methodically through suspension setup. A linear response means that each click of adjustment produces a predictable, proportional change in feel — there are no sudden steps or dead zones in the adjustment range. Combined with the three included spring rates, a Öhlins-trained technician can dial the front end to support maximum traction under acceleration and confident, planted stability through high-speed corners.
The broad tuning envelope also makes the FKR 103 an excellent platform for riders progressing through track day levels, as the setup can evolve alongside skill and pace without requiring a damper change.
Fitment & Compatibility
This kit is designed and validated for the following application:
- Yamaha YZF-R1 M RN32 (2015–2016)
- Yamaha YZF-R1 M RN49 (2017–2019)
