With its sleek lines and aggressive styling, this bike demands attention on the road and is perfect for those seeking a blend of practicality and excitement. At the heart of the RS4 125 lies a robust 124.80cc single-cylinder four-stroke engine that delivers an impressive 16.04 horsepower at 11.7 kW. This spirited engine, with a high compression ratio of 12.5:1, is paired with a 6-speed gearbox, allowing riders to experience a thrilling ride whether navigating city streets or cruising on winding roads. The liquid cooling system ensures optimal performance, while the multi-plate clutch in an oil bath contributes to smooth gear transitions.

The Aprilia RS4 125 is not just about power; it also boasts a well-crafted chassis and advanced suspension that enhance both handling and comfort. The aluminum perimeter frame contributes to its lightweight construction, weighing in at just 120 kg (264.6 lbs), making it incredibly nimble. The front features a 40 mm upside-down hydraulic fork, delivering 110 mm of travel, while the rear swingarm is equipped with a hydraulic monoshock offering 130 mm of travel. Coupled with high-performance braking components, including a 300 mm stainless steel disc with a radial 4-piston caliper at the front, the RS4 125 ensures confident handling and stopping power. Riders can also appreciate the adjustable spring preload that caters to individual preferences, enhancing ride quality. **

Pros

  • Lightweight and Agile: At just 120 kg, the RS4 125 offers exceptional maneuverability, making it perfect for both city commuting and spirited rides.
  • Sporty Performance: The powerful engine and 6-speed transmission provide a thrilling experience, allowing riders to tap into its sporty nature effortlessly.

  • Fuel Capacity: The 14.5-liter tank might require more frequent refueling on longer rides, which could limit travel distance without stops.
