About the Product

Öhlins FKR Supersport Front Fork Cartridge Kit

Yamaha YZF-R1 (Kayaba Forks) 2015–present

MotoGP-Derived Front Suspension Performance

Upgrade the front-end performance of your Yamaha YZF-R1 with the Öhlins FKR Supersport Front Fork Cartridge Kit, a race-engineered suspension system developed directly from Moto2, Moto3, and World Superbike competition.

Designed specifically for 2015-2019 Yamaha YZF-R1 models equipped with Kayaba (KYB) front forks, this advanced cartridge kit replaces the OEM fork internals with Öhlins’ race-derived TTX technology. The result is improved damping response, greater front tire grip, and exceptional chassis stability under the most demanding riding conditions.

Built for serious riders and racers, the FKR cartridge system delivers a wide adjustment range and predictable suspension behavior, allowing riders to fine-tune the front suspension for track conditions, tire choice, and riding style.

Performance Benefits

• Increased front-end stability under hard braking

• Reduced fork dive and improved brake support

• Enhanced front tire feedback and grip

• Faster damping response for improved chassis balance

• Greater confidence during corner entry and trail braking

• Consistent suspension performance during aggressive riding

Advanced Öhlins FKR Technology

TTX 25 Pressurized Damping System

The FKR cartridge kit utilizes Öhlins’ TTX 25 twin-tube damping technology, maintaining balanced pressure within the system to ensure consistent damping performance during extreme track conditions.

Spring-Pressurized Cartridge Design

A spring-pressurized system replaces traditional gas pressurization, delivering a smoother damping curve, increased reliability, and easier maintenance.

Race-Developed Internal Architecture

Optimized piston and shaft design reduce pressure buildup inside the cartridge, resulting in faster damping response and improved traction and bump absorption.

Professional-Level Adjustability

External compression, rebound, and preload adjustments allow riders to precisely tune suspension performance for rider weight, track layout, and tire selection.
