Rider Profile

Best ForThis bike suits newer to intermediate riders thanks to its modest power output and manageable single-cylinder character.
PurposeIt is built as a retro-styled allround machine best suited to relaxed city riding and light mixed-terrain use rather than serious off-roading or long highway touring.
Rider FitThe tall-ish seat height and moderate dry weight make it manageable for average to taller riders, though shorter riders may find ground reach a stretch.
CharacterIt has a classic scrambler-like feel with torquey low-end delivery, air cooling, and a simple mechanical charm rather than outright performance.
Not Ideal ForIt is not a good fit for riders wanting high-speed touring, serious off-road capability, or sport-bike levels of cornering performance.
