Öhlins FKR Cartridge Kit Racing TTX 25 FKR 102 – Yamaha YZF-R6 RJ27 (2017–2026)

The Öhlins FKR Cartridge Kit Racing (TTX 25) FKR 102 transforms the stock Kayaba fork on your Yamaha YZF-R6 RJ27 into a precision racing tool, delivering the kind of all-day comfort and confident fit on the brake and apex that circuit riding demands. Engineered directly from top-level motorsport development, this closed, spring-pressurised system eliminates the risk of pressure loss through leaks and keeps damping performance consistent from the first lap to the last.

Key Features

• TTX technology with a redesigned piston and 8 mm piston rod reduces internal pressure, producing fast, precise damping response that feels natural and predictable under sustained track use.
• Closed, spring-pressurised system maintains consistent performance throughout a full race session — no fade, no unwanted variation in feel.
• Linear damping characteristic with fine-tuning adjustment delivers optimal traction and improved stability across a wide range of corner speeds and track surfaces.
• Designed as a direct fitment for Yamaha YZF-R6 RJ27 models equipped with the original Kayaba fork — no adaptation or machining required.
• Includes three fork spring rates (9.5, 10.0 and 10.5 N/mm from the 04744 series) to suit different rider weights, riding styles and circuit demands.
• Installation by an authorised Öhlins Service Centre is recommended to ensure correct setup and full performance from day one.

Motorsport Engineering for the Yamaha YZF-R6

Öhlins developed the FKR Cartridge Kit Racing around one goal: to give club and professional racers a front-end that communicates clearly and responds immediately. The TTX (Twin Tube X) principle, refined over decades of Grand Prix and Superbike competition, relies on the closed pressurised circuit to keep the oil column stable under the heavy braking forces and rapid direction changes that the YZF-R6 platform encounters at the limit. The result is a fork that feels composed rather than vague, and that allows the rider to trail-brake deeper and carry more corner speed with genuine confidence.

Adjustability and Tuning

The three-spring package — 9.5, 10.0 and 10.5 N/mm — means you can dial in the spring rate that matches your weight and setup before turning a wheel in anger, rather than discovering a mismatch mid-session. From there, the damping adjustment range allows fine incremental changes that make the difference between a fork that fights you and one that works with you, session after session.

Fitment and Compatibility

The Öhlins FKR 102 is a direct-fit cartridge kit for the following model:
