DescriptionThe whole story▼
Precision-engineered from quality materials, the K-Tech travel indicator 25K-028A slips directly onto the fork leg of the Aprilia RS 660 without removing the forks from the bike, giving you an immediate, accurate read of used suspension travel so your chassis setup is always grounded in real data.
Key Features
- Designed to mount onto the installed fork with no disassembly required, saving valuable time in the paddock or garage
- 41 mm inner diameter machined to a precise fit on the Aprilia RS 660 fork tube — no slop, no false readings
- Clearly indicates the maximum suspension travel used during a session, letting you identify compression and rebound settings that need adjustment
- Lightweight, low-profile design adds nothing meaningful to unsprung mass while delivering consistent, repeatable results
- Supports informed, data-led suspension tuning whether you are setting up for track days or spirited road riding
Build Quality & Materials
K-Tech manufactures suspension components and associated tooling to the same exacting standards used in their race-division products. The 25K-028A travel indicator reflects that heritage: the bore is held to a tight tolerance so the ring moves freely along the fork stanchion under fork compression but stays put once the fork rebounds, marking the furthest point of travel with no ambiguity. The material choice and finish ensure the indicator resists the knocks and vibration of real-world riding without degrading its measurement accuracy over time.
How It Helps Your Setup
Knowing how much fork travel is being consumed under braking and through corners is fundamental to dialling in spring preload, compression and rebound damping. Fit the 25K-028A at the start of a session, push it up to the seal, and ride normally. After the session the ring's position on the stanchion tells you exactly how far the fork compressed. Compare that figure against your target travel and adjust accordingly — a straightforward process that replaces guesswork with repeatable, measurable feedback.
Fitment & Compatibility
This travel indicator is specifically sized for the Aprilia RS 660 across the full production run from 2020 to 2026. The 41 mm inner diameter matches the fork stanchion diameter used on these model years. Always verify your fork tube diameter before ordering if your machine has been fitted with non-standard forks.
