About the Honda ST90

Mighty Dax identity, fork dimensions and separate front and rear brake applications.

Honda Motorcycle Logo

The Honda ST90 Mighty Dax uses a horizontal four-stroke OHC engine. This guide focuses on its 1973–1975 fork seals, front and rear brake shoes, and individual clutch plates.

Build a brake and fork service order

Choose shoes for the brake position being repaired and compare the fitted fork with the 27 × 39 × 10.5 mm oil-seal pair. If the engine has been replaced, identify it before selecting clutch parts.

Prepare for the repairIdentify your ST90 components

Use these checks when a registration year or a model badge does not identify the fitted parts.

  • ST90 designation and model year checked against the motorcycle and documents.
  • Frame and engine markings, including known replacement-engine details.
  • Fork assembly and full removed-seal dimensions.
  • Front or rear brake position and the fitted wheel and brake assembly.
Need help identifying your ST90?

Contact PartsNMore with the model year, frame and engine markings, and clear photographs of the component being repaired.

Honda ST90 parts for repairs and restoration

Choose the repair you are working on, then check the model, year, specifications and package contents on each part before ordering.

Handlebars, mirrors and custom controls

For an ST90 with replacement bars or mirrors, check the fitted control mounts and available clearance. Measure first so that a styling choice does not compromise cable reach or control movement.

Universal accessories require measurement and may need modification; they are not confirmed direct-fit ST90 parts.
