Öhlins Cartridge Kit Racing TTX 25 FKR 127 – Honda CBR 1000 RR-R SC82 (2020–2026)

The Öhlins FKR 127 Cartridge Kit Racing brings TTX 25 technology to the Honda CBR 1000 RR-R SC82, replacing the factory fork internals with a closed, spring-suppressed system built entirely around the demands of competitive circuit riding. Where conventional gas-pressure cartridges compromise under sustained track abuse, this unit's sealed architecture eliminates pressure loss through leakage and delivers consistent damping lap after lap.

Key Features

• TTX 25 twin-tube technology with a newly developed piston and 8 mm piston rod reduces internal pressure for faster response and a linear damping characteristic across the full stroke.
• Closed, spring-suppressed system removes the risk of gas leakage that plagues conventional open-bath cartridge designs, ensuring performance never degrades mid-session.
• Three spring rates included (9.5, 10.0 and 10.5 N/mm, 04744-series) allow precise setup for rider weight and circuit conditions without purchasing additional hardware.
• Finer adjustment range compared to standard gas-pressure systems gives engineers and riders more tuning resolution over compression and rebound damping.
• Improved traction and chassis stability under hard braking and corner entry — the exact conditions where the SC82's immense power demands the most from its fork.
• Compatible exclusively with Öhlins fork FL 941, ensuring engineering tolerances are maintained and performance gains are fully realised.

Engineering & Build Quality

Öhlins engineers designed the FKR 127 from the ground up for high-end motorsport. The TTX (Twin Tube X-over) architecture routes oil through a patented cross-flow valve arrangement, separating compression and rebound circuits more cleanly than single-tube designs. The result is a damping curve that remains predictable even when oil temperature rises during extended track sessions. The 8 mm piston rod — larger than the factory specification — increases rigidity under lateral loads and contributes directly to the reduced internal operating pressure that defines TTX performance.

Every component is manufactured to Öhlins' motorsport tolerances. The cartridge body, piston and valve stack are engineered as an integrated system rather than an assembly of off-the-shelf parts, which is why Öhlins specifies installation by an authorised Öhlins Service Centre to guarantee correct preload, oil volume and damping settings from the first session.

Track Performance

On a machine as capable as the Honda CBR 1000 RR-R SC82, the difference between a compliant front end and a nervous one is felt immediately at the apex. The FKR 127's linear damping characteristic means the fork compresses progressively under braking rather than diving sharply and then stiffening, giving the rider genuine confidence to brake late and carry speed through the corner. Combined with the three included spring rates, the kit allows a fully tailored setup regardless of whether the circuit demands a soft, plush front for slow chicanes or a stiffer package for high-speed sweepers.

Important Notice

The Öhlins FKR 127 Cartridge Kit is designed for race use only. It is not approved for use on public roads in Germany under the StVZO, and should not be used on road-registered motorcycles. It is compatible exclusively with the Honda CBR 1000 RR-R SC82 (2020–2026) equipped with Öhlins fork FL 941 — it is not a fitment for standard CBR 1000 RR-R models with the OEM fork. Installation must be carried out by an authorised Öhlins Service Centre.

Fitment & Compatibility

• Honda CBR 1000 RR-R SC82 (2020–2026)
• Compatible fork: Öhlins FL 941 only
• Not compatible with standard Honda CBR 1000 RR-R models
