How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built purely for enduro racing and technical off-road riding, not as a road or all-round machine.
- Built for
- A featherweight, high-revving single-cylinder racer with razor-sharp handling, huge suspension travel, and a raw, focused competition feel.
- Not ideal for
- This bike is not suitable for riders wanting a comfortable commuter, a passenger-friendly tourer, or a beginner-friendly first motorcycle.
