About the Product

Öhlins FKR Supersport Front Fork Cartridge Kit

Yamaha YZF-R1 (Kayaba Forks) 2015–2019

Race-Developed TTX 25 Front Suspension Performance

Upgrade your Yamaha 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 for riders who demand maximum front-end precision, this cartridge kit delivers superior damping response, enhanced braking stability, and exceptional chassis control for track and aggressive sport riding.

Specifically designed for Yamaha YZF-R1 models equipped with Kayaba (KYB) front forks, the FKR cartridge kit replaces the OEM internal fork components with Öhlins’ advanced TTX 25 pressurized damping technology, dramatically improving front tire grip, stability, and rider feedback.

Performance Benefits

• Superior braking stability and reduced fork dive

• Faster damping response for improved chassis balance

• Increased front tire traction and feedback

• Greater confidence during corner entry and trail braking

• Consistent performance under demanding track conditions

• Expanded adjustment range for precise suspension tuning

FKR Supersport cartridges are developed for Superstock and Supersport racing classes, offering professional-level suspension performance.

Advanced Öhlins Suspension Technology

TTX 25 Pressurized Cartridge System

The twin-tube TTX design maintains balanced internal pressure, ensuring consistent damping behavior and improved control during aggressive riding and racing conditions.

Spring-Pressurized Design

The spring-pressurized system eliminates the risk of gas leakage while delivering smoother damping curves, simplified maintenance, and more consistent suspension performance.

Race-Optimized Internal Components

A redesigned piston and 8-mm piston shaft reduce pressure buildup, producing faster damping response and more linear suspension behavior for improved grip and bump absorption.

Professional-Level Tunability

The cartridge kit offers a wide adjustment range, allowing riders and race technicians to precisely dial in suspension performance based on rider weight, track conditions, and tire choice.
