The Hyosung SF is marked with traditional scooter styling. There are three trim levels offered, including the base, SF Racing, and SF Rally. Each operates on the foundation of the 49cc, two-stroke single cylinder. The base Hyosung SF, as well as the trim upgrades, are all full fairing scooters—the frame, engine, and drive components are covered from front to back. The only visible aspect is the hearty muffler, which does a good job in quieting the vintage two-stroke sound, without detracting from engine performance.
