Best for: Built for boulevard cruising and making a bold visual statement rather than outright performance or long-distance touring.
Built for: A muscular, iconic cruiser with a fat rear tire stance, strong low-end torque, and unmistakable classic Harley presence.
Not ideal for: Not the right choice for riders seeking nimble cornering, off-road capability, or a lightweight, agile everyday commuter.
