How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It exists purely to conquer extreme low-speed technical terrain like rocks, logs, and steep inclines through precise balance and control rather than speed.
- Built for
- It feels featherlight, incredibly responsive, and almost telepathic in tight technical sections, rewarding finesse over brute force.
- Not ideal for
- This is not for anyone wanting a comfortable seat, highway capability, passenger carrying, or general road and touring use.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
