Best for: Built primarily for long-distance highway touring with a commanding, stable ride rather than quick sporty handling.
Built for: A confident, laid-back cruiser-tourer personality that favors relaxed torque delivery, long-haul comfort, and classic V-twin presence over outright speed or nimbleness.
Not ideal for: Not a good fit for riders seeking lightweight agility, off-road capability, or a sharp cornering experience.
