Best for: Built for style-driven boulevard cruising and short blasts rather than outright speed or long-distance touring.
Built for: A muscular, fat-tired custom cruiser that trades cornering agility for big V-twin torque and unmistakable Dyna attitude.
Not ideal for: Not a good fit for riders seeking sharp cornering performance, off-road capability, or dedicated long-haul touring comfort.

Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
