Best for: Built for laid-back boulevard cruising and image-driven riding rather than outright performance.
Built for: A muscular, torque-rich cruiser icon that rewards relaxed throttle rolls and a laid-back riding style over aggressive cornering.
Not ideal for: Not the right choice for riders seeking sharp cornering agility, off-road capability, or high-speed sport performance.
