Overview

Introducing the 1999 Honda RS 125, a nimble and spirited entry into the world of sport motorcycles that has captured the hearts of enthusiasts since its debut. Designed with the beginner and experienced rider in mind, the RS 125 strikes a perfect balance between performance and usability. This lightweight machine, weighing in at just 143 kg (315.3 pounds), is engineered to deliver an exhilarating ride without overwhelming those new to the sportbike genre. With its aggressive styling and vibrant color schemes, the RS 125 is not just a motorcycle; it’s a statement of youthful exuberance and freedom on two wheels. At the heart of the RS 125 is its powerful single-cylinder, two-stroke engine that boasts a displacement of 125cc. This compact powerplant generates a respectable 15 HP at 7000 RPM and a torque of 15 Nm at 6250 RPM, ensuring lively acceleration and a top speed of 124 km/h (77.1 mph). The liquid cooling system helps maintain optimal temperatures, allowing the rider to push the limits on both the street and the track. The 6-speed gearbox, paired with a chain final drive, contributes to a thrilling, responsive ride, making it ideal for both spirited cornering and relaxed cruising. With an astonishing fuel consumption rate of just 0.52 litres/100 km (452.35 mpg), the RS 125 is as economical as it is fun, promising long rides without frequent fuel stops. The RS 125 is equipped with features that further enhance its sport-oriented performance. The front and rear braking systems utilize single discs, with a robust 320 mm front disc providing confident stopping power. Coupled with a front suspension travel of 120 mm, the RS 125 is designed to handle the twists and turns of any road with ease and precision. Riders will appreciate the 780 mm seat height, which provides a comfortable and manageable riding position, especially for those with shorter inseams. The electric starter adds convenience, allowing for quick and hassle-free rides at a moment's notice, making this bike a true delight for daily commutes or weekend adventures. **

Pros

  • Lightweight & Agile: Weighing just 143 kg, the RS 125 offers exceptional handling and maneuverability, making it perfect for both novice and seasoned riders.
  • Economical Fuel Consumption: With an impressive fuel efficiency of 452.35 mpg, riders can enjoy longer journeys with fewer stops at the pump.
  • Sporty Performance: The robust 125cc two-stroke engine delivers responsive power and acceleration, ideal for spirited rides on twisty roads or tracks.

Cons

  • Limited Power for Highway Use: While the RS 125 excels in urban settings, its 15 HP may feel underwhelming for sustained highway cruising.
  • Two-Stroke Maintenance: The two-stroke engine requires more frequent maintenance compared to four-stroke counterparts, which can be a drawback for some riders.
  • Minimal Storage Options: With a focus on sport performance, the RS 125 lacks the practicality of storage compartments, which may limit its usability for daily commuting.
