Best for: Built for boulevard cruising and strong straight-line acceleration rather than nimble cornering or long-distance touring.
Built for: A muscular, torque-heavy power cruiser with a big V-twin rumble, aggressive styling, and a wide 240-section rear tire that defines its identity.
Not ideal for: Not for riders seeking light, flickable handling, off-road capability, or a nimble city commuter.
