How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built purely for competitive and recreational trials riding, tackling rocks, logs, steep climbs and tight technical obstacles at very low speeds.
- Built for
- A featherweight, high-revving two-stroke with razor-sharp response, built for precision throttle and clutch work rather than outright speed.
- Not ideal for
- This is not suitable for anyone wanting a comfortable, fast, or long-distance road-going motorcycle, as it lacks a real seat, fuel range, and highway capability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
