About the Product

Öhlins FKR Supersport Front Fork Cartridge Kit

Yamaha YZF-R1M (Öhlins FL 940 / FL 942 / FL 943 Forks) 2020–Present

MotoGP-Derived Front Suspension Performance

Unlock the full racing potential of your Yamaha YZF-R1M with the Öhlins 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 Öhlins electronic FL 940 / FL 942 / FL 943 forks, the FKR cartridge kit replaces the internal fork components with race-engineered Öhlins 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 Öhlins FKR Technology

TTX 25 Pressurized Damping System

The FKR cartridge kit uses Öhlins 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.
