How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built purely for competitive and recreational trials riding, tackling obstacles, rocks, logs, and steep technical terrain at very low speed with extreme control.
- Built for
- An ultra-light, razor-sharp two-stroke tool built entirely for precision, balance, and momentary bursts of throttle control rather than outright speed.
- Not ideal for
- This bike is not for anyone wanting a comfortable seat, sustained highway speed, passenger capability, or long-distance touring range.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
