With its sleek lines and vibrant color options, this scooter is not just a mode of transportation; it's a statement of modern mobility.

Under the hood, the Neos 4S is powered by a peppy 49.4cc single-cylinder, four-stroke engine that delivers a modest yet spirited 3.08 horsepower at 7000 RPM, coupled with 3.15 Nm of torque. This combination provides a lively ride, perfect for darting in and out of traffic, while the automatic gearbox ensures a seamless experience for riders of all skill levels.

The scooter's lightweight frame, weighing in at just 95 kg, contributes to its nimbleness, making it an ideal companion for both short commutes and extended joyrides.

The Neos 4S is packed with features that enhance both comfort and safety. Its telescopic front fork suspension and unit swing rear suspension work in harmony to provide a smooth ride over uneven surfaces, while the single disc front brake and rear drum brake offer reliable stopping power. For added convenience, the scooter is equipped with both electric and kick starters, giving riders flexibility in how they power up. With a seat height of just 790 mm, it caters to a wide range of riders, ensuring that everyone can enjoy the thrill of the ride.

  2. Small Storage Capacity: As a scooter, storage space is limited, which may not accommodate larger items or gear.
  3. Basic Features: While it excels at being a reliable commuter, the Neos 4S may lack advanced technology and features found in more premium models.
