The Aprilia Leonardo 120-154 is a popular scooter model that was produced by the Italian motorcycle manufacturer Aprilia from 1997 to 2006. It was known for its sleek and modern design, offering a practical and stylish option for urban commuting. The Leonardo was available in two engine sizes: the 125cc and 150cc, both air-cooled, four-stroke single-cylinder engines, providing a comfortable and efficient riding experience. The 125cc version delivered a smooth and responsive power delivery, making it suitable for city riding and short trips, while the 150cc model offered a bit more power for highway riding. The Leonardo's distinctive design featured a low-slung seat, a sloping front fairing, and a spacious under-seat storage compartment. The scooter also boasted a comfortable riding position and a responsive suspension system that provided a smooth and enjoyable ride, even on rough roads. It was equipped with features like a digital instrument panel, a rear luggage rack, and an optional windscreen, enhancing both practicality and comfort. As with many Aprilia models, the Leonardo was designed with a sporty and aggressive aesthetic, making it stand out in the scooter market. Its agility and maneuverability, combined with its relatively low price, made it a popular choice for riders of all ages, from urban commuters to weekend leisure riders. However, while the Leonardo enjoyed a strong presence in the market, it has since been discontinued, but its legacy continues to inspire current models and continues to be sought after by enthusiasts.
