Rider Profile

Best ForBest suited to riders with genuine off-road or enduro experience, as this is a light, punchy two-stroke that rewards active riding and can be unforgiving of clumsy inputs.
PurposeBuilt purely for cross-country and motocross use, not as a road or commuting machine, with its low top speed reflecting a focus on trail acceleration and control rather than outright velocity.
Rider FitAt just 110 kg with a tall, narrow enduro stance, it demands active standing-up riding, strong legs, and good balance rather than raw strength.
CharacterA raw, lightweight two-stroke enduro bike with sharp throttle response and minimal creature comforts, delivering an old-school dirt bike experience.
Not Ideal ForNot a good fit for riders wanting highway comfort, passenger capability, or a modern smooth power delivery.
