How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a bold styling statement and boulevard cruiser, it's meant for relaxed, image-driven riding rather than outright performance or sport handling.
- Built for
- It has the soulful, torque-heavy pulse typical of a big-inch 45-degree V-twin, delivering laid-back, deliberate power rather than high-revving excitement.
- Not ideal for
- This is not the bike for riders seeking agile cornering, off-road capability, or a light, flickable ride through tight city traffic.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
