Best for: Economical urban commuting and short errands. A no-frills, fuel-sipping city runabout with light touring ability at best.
Built for: Simple, reliable, air-cooled single-cylinder classic commuter. Unintimidating, cheap to run, and endearingly basic.
Not ideal for: Not for speed seekers, highway touring, two-up long trips, or off-road use. Underpowered for experienced riders wanting thrills.
