Best for: Built for boulevard cruising and making a visual statement with drag-style styling rather than for outright speed or distance touring.
Built for: A muscular, low-slung factory custom with strong torque off the line, deep exhaust presence, and drag-bike attitude rather than outright top-end performance.
Not ideal for: Not a good fit for riders seeking agile cornering, off-road capability, long-distance touring comfort, or a passenger-friendly setup.
