DescriptionThe whole story

Getting your suspension dialled in shouldn't require a track day or specialist workshop visit. The K-Tech Fork Travel Indicator 25K-028A fits directly onto the Kawasaki Ninja 400 fork leg while installed, letting you read used travel at a glance and make informed, repeatable setup changes whether you're commuting, touring or exploring your local twisties.

Key Features

  • Measures actual fork travel consumed during real-world riding, giving you the data to set sag and compression correctly the first time.
  • Fits the 43 mm fork legs of the Kawasaki Ninja 400 (2018–2023) without removing the forks from the bike.
  • Simple slide-ring design means no tools or complicated procedure — install it in minutes and ride immediately.
  • Compact and lightweight, it stays out of the way during normal riding and resets cleanly for back-to-back testing.
  • Genuine K-Tech quality, engineered to the same standard as the brand's premium suspension components used in professional racing.

Everyday Suspension Tuning Made Accessible

Many riders leave factory suspension settings untouched simply because measuring fork travel feels intimidating. The 25K-028A removes that barrier entirely. Slide the indicator onto the fork stanchion before your ride, go through your normal routine — a commute, a weekend road run, a track session — and check the position afterwards. The ring shows you exactly how much travel was used, telling you whether your preload and compression settings suit your weight, riding style and road conditions.

This kind of feedback is what separates riders who genuinely understand their chassis from those who rely on guesswork. Once you can see the data, even small preload adjustments become meaningful, and the improvement in confidence and comfort is immediate.

Build Quality and Fitment

K-Tech manufactures this indicator specifically for the 43 mm fork diameter of the Ninja 400, ensuring a secure, rattle-free fit. There is no risk of the ring migrating up the stanchion under vibration, so readings remain accurate across a full ride. The part number 25K-028A is unique to this fitment, making it straightforward to verify compatibility before ordering.
