Overview

The 2019 Aprilia RS 50 stands as a formidable entry in the sport motorcycle category, perfectly tailored for novice riders and those looking to hone their skills without sacrificing performance. Known for its aggressive styling that echoes the aesthetics of its larger RS siblings, this machine embodies the spirit of the racetrack while remaining agile and manageable for everyday riding. With its lightweight construction and sporty demeanor, the RS 50 is designed to capture the hearts of young enthusiasts and seasoned riders alike, offering a thrilling experience at an accessible price point. At the heart of the RS 50 lies a potent 50cc single-cylinder, two-stroke engine that packs a punch, producing exhilarating performance ideal for spirited rides. Boasting a compression ratio of 11.5:1, this engine is tailored for responsiveness, paired with a 6-speed gearbox that allows for seamless transitions through gears, making it perfect for both city commuting and twisty backroads. The liquid cooling system ensures optimal temperature management, while the carburettor setup from Dell’Orto delivers precise fuel-air mixture for that exhilarating acceleration. With a fuel consumption of just 2.48 liters per 100 km, riders can enjoy extended journeys without the constant worry of refueling, achieving an impressive 94.85 mpg. The chassis and suspension of the Aprilia RS 50 further enhance its appeal, featuring an aluminum perimeter frame that not only provides rigidity and stability but also contributes to its lightweight design at 132 kg (291 lbs). The front end is equipped with a 40 mm upside-down fork, offering 120 mm of travel for exceptional handling, while the asymmetrical swingarm and rear suspension provide 110 mm of travel to absorb bumps effortlessly. Stopping power is delivered through a robust braking system, with a 300 mm single disc at the front and a 218 mm disc at the rear, ensuring reliable performance even during aggressive riding. The bike also boasts an electric starter and a sleek aesthetic available in an array of captivating colors, including White, Silver, Red, and Black. **

Pros

  • Lightweight and Agile: The aluminum frame and low weight make the RS 50 incredibly nimble, perfect for urban environments and tight corners.
  • Fuel Efficiency: With an exceptional fuel consumption rate, this bike allows for longer rides with fewer stops at the pump.
  • Sporty Aesthetics: The aggressive styling and race-inspired design make the RS 50 visually striking and appealing to young riders.

Cons
