DescriptionThe whole story▼
The Öhlins FKR 102 Cartridge Kit Racing (TTX 25) is the most direct path to genuine race-level front-end performance on your Yamaha YZF-R1, covering the RN32, RN49 and RN65 generations from 2015 through 2026. Engineered around Öhlins' closed, spring-pressurised FKR system, it replaces the standard Kayaba internals with a purpose-built cartridge that transforms how the R1 reads and reacts to the track surface — delivering the kind of precise, linear damping response that serious lap times demand.
Key Features
- Closed, spring-pressurised FKR system operates at reduced internal pressure compared with conventional gas-pressure cartridges, making it easier to service and tune between sessions.
- Newly developed piston paired with an 8 mm piston rod reduces friction and internal resistance for noticeably faster damping response.
- Linear damping characteristic translates directly into improved rear-wheel traction and more predictable chassis behaviour under braking and mid-corner.
- Three fork spring rates included — 9.5, 10.0 and 10.5 N/mm (04744-series) — letting you dial in the setup to suit your weight, riding style and circuit.
- Bolt-in fitment for Yamaha YZF-R1 models equipped with the original Kayaba fork; no external chassis modifications required.
- Finer, more accessible damping adjustment compared with stock internals, maximising stability and control across a full race weekend.
TTX 25 Technology and Build Quality
The TTX 25 cartridge is drawn from Öhlins' extensive WorldSBK and MotoGP development programme, adapted for club-level and privateer racers who expect factory-grade feel without factory-team budgets. The spring-pressurised, closed-system design eliminates the need for high charge pressures, which in practice means the damping curve responds more immediately to small inputs — the micro-bumps, mid-corner kerbs and late braking zones that separate a good lap from a great one on the YZF-R1 platform.
The 8 mm piston rod is a meaningful upgrade over standard hardware. Greater rigidity under load reduces flex-induced damping inconsistency, keeping the feel consistent from lap one to the final flying lap of a long session. Combined with the new piston geometry, stiction is kept to a minimum even as the fork works rapidly through its travel.
Practical Usability and Setup
Arriving with a complete spring set spanning three rates, the FKR 102 kit removes the guesswork from initial setup. Rather than ordering individual springs after fitting, you have the full range on hand to test during a shakedown session and confirm the correct rate before the competitive day begins. The accessible damping adjusters mean changes can be made quickly in the paddock without specialist tooling for every adjustment.
Installation should be carried out by an authorised Öhlins Service Centre to ensure correct preload, damping settings and oil fill. Once set up correctly, the system rewards the rider with consistent, repeatable behaviour — a genuine advantage when you need the front end to feel the same on lap 20 as it did on lap 1.
Fitment and Compatibility
The Öhlins FKR 102 Cartridge Kit is designed exclusively for the following models fitted with the original Kayaba front fork:
- Yamaha YZF-R1 RN32 (2015-2016)
- Yamaha YZF-R1 RN49 (2017-2020)
- Yamaha YZF-R1 RN65 (2021-2026)
This kit is approved for race track use only. It carries no road-use approval (StVZO) and must not be fitted to a vehicle used on public roads in Germany or other jurisdictions where such approval is required. Always verify local regulations before fitting.
