How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a bold styling statement and boulevard cruiser rather than a performance or utility machine.
- Built for
- A rumbling, big-inch V-twin custom with laid-back ergonomics, raked-out front end, and unmistakable American chopper-inspired presence.
- Not ideal for
- Not a good fit for riders wanting agile cornering, off-road capability, or a sporty, high-rev riding experience.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
