Best for: Built for boulevard cruising and long, relaxed highway stretches with big-twin torque rather than for outright speed or sharp cornering.
Built for: A loud, torque-rich boxer cruiser with strong presence, classic styling, and a shaft-driven drivetrain that rewards a laid-back, throttle-roll-on riding style.
Not ideal for: Not a good fit for new riders, those seeking agile flickable handling, or anyone planning to take it off-road.
