Overview

### 1985 Hyosung RX 125: The Agile Cross-Motocross Champion The 1985 Hyosung RX 125 stands as a remarkable entry in the world of cross-motocross motorcycles, perfectly positioned for both novice riders and seasoned enthusiasts alike. With its nimble frame, lightweight build, and spirited performance, the RX 125 captures the essence of off-road adventure while offering accessibility for riders of various skill levels. As one of Hyosung's pioneering models in the motocross category, it set the stage for the brand's reputation in producing reliable and engaging two-stroke machines. At the heart of the RX 125 lies a robust single-cylinder, two-stroke engine with a displacement of 124cc, delivering a thrilling 34 horsepower at an exhilarating 10,750 RPM. This powerplant isn't just about numbers; it's designed for exhilarating performance that translates into a top speed of 130 km/h (80.8 mph). The engine's 14.5:1 compression ratio and liquid cooling system ensure that it operates efficiently, even during the most demanding off-road excursions. Paired with a six-speed gearbox, the RX 125 provides smooth gear transitions and allows riders to harness the full potential of its power, making every ride a blend of excitement and ease. The RX 125 is equipped with features that enhance both performance and rider comfort. The single disc front brake provides responsive stopping power, giving riders confidence on varied terrains, while the expanding rear brake offers reliable deceleration. The lightweight design, at just 91 kg (200.6 pounds), ensures that the motorcycle remains agile and easy to maneuver, whether you're tackling tight corners or navigating through rugged trails. With a fuel capacity of 8.5 liters (2.25 gallons), riders can enjoy extended rides without frequent pit stops, allowing for longer adventures and more time on the dirt. **

Pros

  • Lightweight and Agile: At 91 kg, the RX 125 is easy to handle, enhancing maneuverability on challenging trails.
  • Powerful Engine Performance: With 34 HP and a top speed of 130 km/h, it offers thrilling acceleration and speed for a 125cc bike.
  • Versatile Gearbox: The 6-speed transmission provides flexibility and responsiveness, enhancing your riding experience across various terrains.

Cons

  • Limited Comfort Features: As a pure cross-motocross machine, it may lack the comfort features found in more touring-oriented bikes.
  • Two-Stroke Maintenance: The two-stroke engine may require more frequent maintenance and tuning compared to four-stroke counterparts.
  • Basic Suspension: While adequate for most off-road conditions, the suspension may not be as advanced as those found on more modern motocross bikes, potentially limiting performance on extremely rough terrain.
