Rider Profile

Best ForA friendly, low-intimidation single that suits newer riders or experienced riders wanting a simple, analog machine.
PurposeBuilt for classic-styled city riding, short jaunts, and enjoying the mechanical simplicity of a kick-start single rather than for outright performance.
Rider FitLight weight and a moderate seat height make it easy for shorter or less physically strong riders to manage at low speed and in traffic.
CharacterA charming, old-school retro roadster that rewards relaxed, unhurried riding with plenty of mechanical character.
Not Ideal ForNot suited for highway touring, two-up long distances, or riders wanting strong acceleration and modern performance.
