Overview

Introducing the 2011 Derbi GPR 125, a stunning example of Spanish engineering that sits squarely in the sport motorcycle category. Priced competitively at €3966 (approximately £3582 in the UK), this motorcycle offers a perfect blend of performance and accessibility for new riders and seasoned enthusiasts alike. The GPR 125 attracts attention with its sleek, aerodynamic design and vibrant color options—white, red, and black—that make it stand out on the street. It’s a great choice for those looking to dive into the world of sport biking while enjoying the thrill of a lightweight machine. At the heart of the GPR 125 lies a spirited single-cylinder, four-stroke engine with a displacement of 124.76 ccm. This small yet mighty powerplant churns out 15 horsepower at an exhilarating 9250 RPM, allowing the bike to deliver agile acceleration and responsive handling. The liquid-cooled engine, paired with a 6-speed gearbox, offers seamless shifts that enhance the overall riding experience, whether you're navigating through city traffic or carving up twisty backroads. The high compression ratio of 12.0:1 and efficient carburettor fuel system ensure that riders enjoy not just power, but also impressive fuel economy—a crucial aspect for daily commuters. The GPR 125 is equipped with advanced features that elevate its performance and rider confidence. The front suspension boasts a robust 40 mm upside-down fork, providing superb stability and control, while the rear monoshock offers excellent comfort over rough terrain, with a rear travel of 120 mm. Stopping power is equally impressive, thanks to the single disc front brake with a 300 mm diameter and a reliable expanding rear drum brake. The bike's lightweight design (weighing in at just 120 kg) coupled with a power-to-weight ratio of 0.1250 HP/kg ensures that the GPR 125 feels nimble and responsive, making it perfect for both new and experienced riders looking to harness the thrill of sport riding. **

Pros

  • Performance: The GPR 125’s engine delivers impressive power for its class, ensuring an exhilarating ride with smooth acceleration.
  • Lightweight and Nimble: At just 120 kg, the bike is easy to maneuver, making it ideal for city riding and spirited cornering.
  • Advanced Suspension: The combination of an upside-down fork and monoshock rear suspension provides excellent handling and comfort on various road conditions.

Cons

  • Limited Power for Highway Use: While great for city and twisty roads, the 15 HP may feel underwhelming at higher highway speeds.
  • Drum Rear Brake: The rear drum brake may not provide the same level of performance as a disc brake system, particularly in wet conditions.
  • Comfort for Longer Rides: With a sport-oriented design, the seat may become uncomfortable for long-distance journeys, making it better suited for shorter, spirited rides.
