This motorcycle fork tube size chart is built to help riders and builders quickly identify the correct fork diameter across different motorcycle models and years.
It is intended as a practical reference for fork swaps/replacements, front-end rebuilds, suspension upgrades, and custom motorcycle projects.

To use this chart, simply locate your motorcycle brand and model, then compare the listed fork tube diameter with your actual measurement.
*Because motorcycle specifications may vary depending on year, trim, or modifications, we always recommend physically confirming the fork diameter before selecting any aftermarket parts or brackets.

Before You Finish the Fork Work (Quick Tool Check)

Before moving on to cockpit refinement, make sure these fork-side adjustments are completed:

  • Correct stem nut torque and alignment
  • Proper fork oil level setting
  • Smooth steering movement with no binding

Tools commonly used at this stage include a stem nut spanner for precise steering stem adjustment, and a fork oil level gauge tool to ensure consistent suspension performance.

27mm Fork Tubes

▼Next build checkpoint:

27mm fork setups are commonly found on smaller displacement motorcycles and older models. After fork replacement or rebuild, riders often move into early-stage cockpit adjustments such as control reach, cable routing, and grip feel refinement.

  • Re-evaluate basic hand control positioning for comfort and responsiveness
  • Check throttlee and cable routing to avoid unnecessary drag or slack
  • Grip material can significantly change how connected the front-end feels
  • A cleaner cockpit setup—such as using a compact mini LED dashboards—can improve usability

37mm Fork Tubes

▼Next build checkpoint:

After working on 37mm fork setups, even minor cockpit adjustments can make a noticeable difference in control feel:

  • Re-evaluate basic hand control positioning for comfort and responsiveness
  • Check throttlee and cable routing to avoid unnecessary drag or slack
  • Grip material can significantly change how connected the front-end feels
  • A cleaner cockpit setup—such as using a compact mini LED dashboards—can improve usability

Fork tubes in the 30–39mm range? These KiWAV clamp-on brackets are made for exactly this size — no drilling, just clamp onto the fork tube:
