Ohlins FKR 223 TTX 25 Pressurized Front Fork Cartridge Kit

The Öhlins FKR 223 is a race-grade, spring-pressurized front fork cartridge kit built on Öhlins' proven TTX (Twin Tube X) technology. Engineered for high-performance motorcycles, this cartridge kit transforms a stock front fork into a fully adjustable, race-ready suspension system — delivering the feel and performance of an Öhlins complete fork assembly without a full fork replacement.

The FKR series technology is derived directly from Moto3, Moto2, and World Superbike championship racing, developed by Öhlins engineers at their headquarters in Sweden. The result is a cartridge kit that meets the demands of SuperStock and SuperSport competition while remaining suitable for serious street and track day riders.

Key Features:

• TTX Technology: New-generation piston design with an 8mm piston shaft reduces internal pressure buildup for faster, more responsive damping
• Spring Pressurized System: Replaces the older gas-pressurized design for a simpler, more reliable closed system with no risk of gas leakage
• Linear Damping Characteristics: Provides a wider tuning range with improved grip, bump absorption, and chassis stability
• External Adjustability: Externally adjustable compression and rebound damping, plus external spring preload adjustment on both fork legs
• Reduced Shim Sensitivity: Less reactive to shim changes, making fine-tuning easier for different tracks and riding styles
• Consistent Performance Curve: Spring-pressurized system delivers more predictable damping response across all conditions
• Compact Design: Optimized for easy installation into standard OEM fork tubes
• Complete Kit: Includes multiple spring rate options to suit a range of rider weights

Installation requires appropriate special tools and fork oil as detailed in the Öhlins mounting instructions. Spring rate selection should be made based on rider weight per the included recommendations. Professional installation by an authorized Öhlins Service Center is recommended.
