DescriptionThe whole story▼

Setting up your forks correctly on the Yamaha YZF-R6 (RJ27, 2017–2026) no longer requires guesswork. The K-Tech fork travel indicator 25K-028B fits directly onto the installed fork leg and gives you an immediate, accurate read of how much fork travel you are actually using — an essential reference point whether you are dialling in suspension for daily commutes, weekend blasts or circuit sessions.

Key Features

  • Precise travel indication: shows exactly how much fork stroke is being used, so every suspension adjustment is based on real data rather than feel alone.
  • Fits the installed fork: mounts directly to the fork leg without disassembly, making setup quick and genuinely practical for road and track use.
  • Correct inner diameter: 43 mm bore matches the YZF-R6 RJ27 fork tube precisely for a secure, rattle-free fit.
  • K-Tech quality: trusted by professional suspension technicians worldwide, this indicator carries the same engineering standard as K-Tech's full suspension range.
  • Part number 25K-028B: easy to reorder and cross-reference for workshops and private owners alike.

Everyday Usability

For riders who want the best from their R6 without spending hours in the garage, the 25K-028B is the straightforward starting point. Fit it in minutes with the forks in place, ride your usual route or circuit, and return to a clear picture of how the front suspension is behaving. From there, adjusting preload, compression and rebound becomes a logical, evidence-led process rather than trial and error. Whether you are running the standard Yamaha forks or an upgraded K-Tech cartridge kit, the travel indicator pays for itself the first time it saves you from a poorly set-up front end.
