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.

Assumes about 30mm of suspension sag once seated. This is an approximation from category-typical geometry, not a measurement of this bike or of you - sit on one before you buy.
