Rider Profile

Best ForWell suited to beginner and intermediate riders thanks to its light weight, modest power, and forgiving nature.
PurposeBuilt for trail riding, green laning, and lightweight commuting rather than outright speed or highway cruising.
Rider FitIts low 108kg weight and slim frame make it easy to manage for riders of smaller stature or lighter build.
CharacterA classic 1980s two-stroke enduro that rewards playful, momentum-based riding with a buzzy, eager engine.
Not Ideal ForNot a good fit for riders wanting sustained high-speed motorway travel, long-distance touring comfort, or carrying a passenger regularly.
