Precision suspension tuning starts with knowing exactly how much fork travel you are using on track. The K-Tech fork travel indicator 25K-028A fits directly over the fork leg of the Yamaha YZF-R6 (2005–2016) while the forks remain in situ, giving you an immediate, accurate read of fork stroke consumption after every session.
Key Features
- Reveals the exact amount of fork travel used during a session, enabling data-driven suspension setup changes at the track.
- Installs over the fork leg without removing the forks from the bike, saving valuable pit-lane time between sessions.
- Machined to a 41 mm inner diameter — a precise, rattle-free fit on the YZF-R6 fork tubes.
- Genuine K-Tech component manufactured to the same standards as their full suspension rebuild kits.
- Compatible with all YZF-R6 variants across the long-running 2005–2016 production run, covering RJ11 and RJ15 frames.
Why Fork Travel Matters on Track
Running too much travel into the bottom of the stroke causes harsh bottoming and unpredictable mid-corner behaviour; running too little means you are leaving grip on the table. The K-Tech fork travel indicator makes this invisible variable visible. Clip the indicator onto the fork leg before a session, go out and ride, then read the maximum travel used the moment you return to the pit garage. From that single measurement you can decide whether to increase preload, add compression damping, or dial in sag — all with real evidence rather than rider feel alone.
Build Quality & Installation
The 25K-028A is designed to slip straight onto the fork tube of the YZF-R6 while the front end is fully assembled. There is no need to remove the wheel, loosen the fork clamps, or drain the oil. The 41 mm bore sits snugly against the tube so the indicator slides freely under compression but stays exactly where the fork pushes it, marking the maximum stroke point accurately every time.
