Overview

Introducing the 2017 Aprilia RS4 50 Replica, a captivating machine that embodies the spirit of sport riding while catering specifically to younger riders and enthusiasts seeking a thrilling entry into the world of motorcycles. Positioned firmly in the sport category, this lightweight powerhouse is not only an homage to Aprilia's distinguished racing heritage but also an accessible option for those looking to blend performance with everyday practicality. With its striking design cues and vibrant color options of grey, red, and silver, the RS4 50 Replica is sure to turn heads while delivering a heart-pounding ride. At the heart of the RS4 50 Replica lies a robust 49.90cc single-cylinder, two-stroke engine, engineered for spirited performance. Boasting a compression ratio of 11.5:1, this compact powerhouse delivers a remarkable balance of torque and speed, ensuring a responsive ride whether you're navigating city streets or carving through twisty backroads. The engine is complemented by a 6-speed gearbox that allows for seamless shifts, making it perfect for both new riders and seasoned veterans looking for a nimble machine. With liquid cooling and an electronic CDI ignition system, you can count on consistent performance, enhancing rider confidence at every turn. The RS4 50 Replica’s chassis is designed with agility in mind, featuring a 41 mm upside-down front fork that provides 110 mm of wheel travel, and an asymmetric swingarm with a monoshock at the rear that offers 130 mm of travel. This sophisticated suspension setup, combined with a powerful braking system that includes a 300 mm front disc with a radial 4-piston caliper, ensures precise handling and stopping power, allowing riders to tackle corners with ease. Additional features such as an electric starter and a small windscreen add to the bike's practicality, making it an ideal companion for daily commutes or spirited weekend rides. **

Pros

  • Lightweight and Agile: The compact dimensions and low seat height (820 mm) make it easy for new riders to handle and maneuver, offering confidence on the road.
  • Sporty Performance: The two-stroke engine provides a thrilling riding experience, with quick acceleration and high-rev fun that appeals to sport enthusiasts.
  • Attractive Design: The striking aesthetics and vibrant color options ensure that the RS4 50 Replica stands out, making it as much a visual statement as it is a performance machine.

Cons

  • Limited Power for Highway Riding: With a displacement of just 49.90cc, it may struggle to keep up with faster highway traffic, making it more suited for urban environments.
  • Two-Stroke Maintenance: Riders should be prepared for the increased maintenance needs common with two-stroke engines, including oil mixes and more frequent servicing.
  • Restricted Features for Advanced Riders: While great for beginners, experienced riders may find the power and features limiting compared to larger sport bikes.
