Rider Profile

Best ForSuits riders with at least some basic experience, as the air-cooled single and moderate weight make it approachable but not entirely forgiving off-road.
PurposeBuilt primarily for enduro and light off-road use with enough road manners for occasional commuting.
Rider FitA relatively light 190kg wet weight and tall enduro stance make it manageable for average-sized riders comfortable standing on pegs.
CharacterA classic late-1980s air-cooled enduro single that rewards a mechanical, no-frills riding style over outright performance.
Not Ideal ForNot suited for riders seeking highway speed, long-distance touring comfort, or a passenger-friendly setup.
