DescriptionThe whole story▼
Knowing exactly how much fork travel your suspension is using is the foundation of safe, informed setup — and the K-Tech fork travel indicator 25K-028B gives you that knowledge with precision. Designed specifically for the Suzuki GSX-R 1000 across the full 2003–2023 model range, it fits directly over the fork leg while the forks remain installed, letting you read consumed travel at a glance and making suspension tuning a methodical, repeatable process rather than guesswork.
Key Features
- Reveals exactly how much fork travel is being consumed under real riding conditions, giving you the data you need for safe and accurate suspension setup.
- Mounts directly onto the installed fork — no disassembly required, so you can fit it in minutes before a session and remove it just as quickly.
- Engineered to a 43 mm inner diameter, matching the GSX-R 1000's fork tube specification precisely for a secure, rattle-free fit.
- Covers the entire Suzuki GSX-R 1000 lineage from 2003 to 2023, making it a versatile tool across multiple generations of this platform.
- K-Tech quality construction ensures the indicator slides cleanly and reads accurately, whether you are fine-tuning for the road or dialling in a track setup.
Why Fork Travel Indicators Matter
Suspension geometry affects every aspect of how a motorcycle behaves — steering response, braking stability, corner entry confidence and mid-corner composure. Without knowing where in the fork's travel range the bike is operating, adjustments to preload, compression and rebound damping are largely subjective. The K-Tech 25K-028B turns that subjective process into an objective one: fit the indicator, ride a representative circuit or road section, and return with a clear measurement of consumed travel. From there, every subsequent adjustment has a baseline to reference.
Build Quality and Fitment
K-Tech is a respected name in suspension engineering, supplying components and tools to professional race teams as well as serious road riders. The 25K-028B reflects that background — it is built to sit against the fork tube consistently throughout a session without migrating or binding. The 43 mm bore is dimensioned to the GSX-R 1000's upper fork tube, so it seats properly rather than requiring forcing or shimming. Whether you are running the bike in stock trim or have fitted aftermarket fork internals, the indicator works at the outer tube level and is unaffected by internal configuration.
Fitment and Compatibility
This indicator is confirmed for the following model:
- Suzuki GSX-R 1000 — all variants, model years 2003 to 2023
If you are unsure whether your specific variant or limited edition falls within this range, the 43 mm fork tube diameter is the definitive check — any GSX-R 1000 of this generation with 43 mm tubes is compatible.
