Rider Profile

Best ForBest suited to riders with at least some off-road or dual-sport experience, since this is a de-tuned big-single enduro rather than a beginner-friendly street bike.
PurposeDesigned primarily for trail riding and off-road enduro use, with the reduced-effect tuning making it more approachable and less abrupt in its power delivery.
Rider FitIts light 140 kg weight and tall, narrow enduro chassis make it easy to muscle around off-road but the high seat height and firm suspension demand reasonable rider fitness and leg length.
CharacterA raw, purposeful single-cylinder off-roader that rewards active riding and feels most alive picking its way through trails rather than cruising on tarmac.
Not Ideal ForNot a good fit for riders wanting a comfortable, high-speed touring machine or a smooth two-up highway companion.
