How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built for muscular, fat-tired boulevard cruising and image-driven street riding rather than outright speed or distance touring.
- Built for
- A bold, muscular custom cruiser with a fat rear tire stance and thumping air-cooled V-twin character that rewards relaxed, torque-fueled riding over cornering finesse.
- Not ideal for
- Not a good fit for riders seeking sharp cornering agility, high-speed touring comfort, or any serious off-road capability.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
