How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Boulevard cruising and relaxed highway miles with unmistakable presence - built for torquey, straight-line style rather than speed or agility.
- Built for
- Iconic solid-wheel Harley muscle cruiser: huge torque from the Milwaukee-Eight 114, deep exhaust rumble, all about attitude and effortless low-rev thrust.
- Not ideal for
- Not for sport riders, twisty-road chargers, off-road use, or beginners intimidated by heavy machines; poor at nimble maneuvering and spirited cornering.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
