Item Summary For R1M ONLY TTX-technology Fits most large displacement bikes Easier maintenance Spring pressurized system Technology from Moto3 Moto2 and World Superbike Complete setting library About the Product hlins FKR Supersport Front Fork Cartridge Kit Yamaha YZF-R1M (hlins FL 940 / FL 942 / FL 943 Forks) 2020Present MotoGP-Derived Front Suspension Performance Unlock the full racing potential of your Yamaha YZF-R1M with the hlins FKR Supersport Front Fork Cartridge Kit. Developed directly from Moto2, Moto3, and World Superbike racing programs, this advanced cartridge system dramatically improves front-end control, braking stability, and chassis feedback for serious track riders and performance enthusiasts. Designed specifically for YZF-R1M models equipped with hlins electronic FL 940 / FL 942 / FL 943 forks, the FKR cartridge kit replaces the internal fork components with race-engineered hlins TTX technology. The result is faster damping response, improved front tire grip, and more consistent suspension performance during aggressive riding and racing conditions. Performance Benefits Increased front-end stability during hard braking Reduced fork dive and improved brake support Enhanced front tire feedback and traction Faster damping response for improved chassis balance Greater confidence during corner entry and trail braking Consistent suspension performance under extreme track conditions Advanced hlins FKR Technology TTX 25 Pressurized Damping System The FKR cartridge kit uses hlins TTX 25 twin-tube damping technology, maintaining balanced internal pressure to ensure stable and predictable damping performance even during aggressive racing conditions. Spring-Pressurized Cartridge Design The spring-pressurized system replaces traditional gas pressurization, eliminating the risk of gas leakage while delivering a smoother damping curve and simplified maintenance. Race-Developed Internal Architecture A newly designed piston and optimized shaft design reduce pressure buildup inside the cartridge, resulting in faster damping response and more linear suspension behavior. Professional-Level Adjustability External compression, rebound, and preload adjustments allow riders to fine-tune suspension performance based on rider weight, tire selection, and track conditions.
