The APRILIA RS4 125 (2011-) RS4 125 (2011) is a learner-friendly 125cc sports motorcycle, not a car, positioned at the sporty end of the UK lightweight-bike market. Its full fairing borrows race-bike styling, giving it more presence than a basic commuter. It suits newer riders seeking a distinctive first bike for local trips, college or work. Against rivals such as the Honda CBR125R, the RS4 stands out for its racing-inspired looks and focused riding feel, rather than relaxed comfort or practicality. Its manageable size and modest running needs suit learner riders, but it remains a small-capacity bike, not a substitute for larger Aprilias. mycarcheck.com has recorded 558 look-ups across 277 VINs.
