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.
