Provide a classification scheme for mapping the difficulty of trails suitable for off-road motorcycles, known as dirt bikes.

It's important to note that this scale specifically addresses trail conditions. The physical characteristics and examples provided for each scale level should help riders determine whether a trail is suitable for their skill level and the type of bike they are using.

To enhance the verifiability and precision of the scale due to its subjective nature, it is recommended to include additional tags such as smoothness=*, surface=*, tracktype=*, incline=*, and width=*.

Applies to

  • single tracks: highway=path
  • double tracks: highway=track
  • unpaved roads: any alternative highway classifications featuring unpaved surfaces

How to map

This tag should be assigned to a way. You can either assign a specific dirtbike:scale=* value to the entire way or divide the way into segments with individual values.

The scale ranges from 0 to 6. Unlike mtb:scale=*, values should be chosen based on the typical conditions encountered when riding uphill.

Additionally, the dirtbike:scale=? tag can be applied to routes known to accommodate dirt bikes when the precise difficulty level has not been determined.


Value Description Examples
0 Well-maintained gravel or compacted roads.
  • Smooth, packed surfaces.
  • No sections with ruts, rocks, or roots are expected.
  • Wide turns and gentle slopes (<= 15% gradient).
  • No special skills are needed.

1 Ungraded tracks with navigable small obstacles.
  • Loose dirt or gravel.
  • Occasional obstacles such as small ruts, roots, and stones.
  • Wide turns and gentle slopes (<= 20% gradient).
  • Ankle deep water crossings.
  • Requires Basic riding skills

2 Rough tracks with moderate obstacles and slopes
  • Occasional obstacles like medium-sized ruts, rocks, roots
  • Tight turns and moderate slopes (<= 25% gradient)
  • Possibly narrow exposed sections.
  • Knee deep water crossings.
  • Requires intermediate riding skills and good control of the motorcycle.

Possible tagging mistakes


The tag motorcycle=no specifies that it is legally prohibited to ride on a particular path. However, it is sometimes mistakenly used to suggest that a path is unsuitable or hazardous for riding. This constitutes a tagging mistake and should be corrected by using dirtbike:scale=*. On the other hand, roads that are legally off-limits for riding should not carry the dirtbike:scale=* tag.
