How it rides

- It's a lightweight recreational off-road machine designed for trail play, dirt tracks, and learning to ride rather than any kind of speed or highway use.
- Built for

- Not ideal for
- This is not the bike for taller or heavier adults, highway commuting, two-up touring, or anyone seeking real speed or long-distance comfort.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
