How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built purely for competitive and recreational trials riding, where the goal is climbing obstacles, balance, and precise low-speed control rather than covering distance or speed.

- Not ideal for
- This is not the bike for anyone wanting a comfortable commuter, a highway tourer, or a fast road machine, since it has no real seat, minimal fuel range, and no pretense of on-road performance.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
