Key specifications
Overview
Introducing the 2010 Derbi GPR 125 4T 4V, a sleek and spirited contender in the sport motorcycle segment, designed for riders who crave agility without sacrificing style. As a product of the renowned Spanish manufacturer Derbi, this lightweight machine captures the essence of performance-oriented design, making it an ideal choice for both urban commuting and spirited weekend rides. With its aggressive lines and aerodynamic profile, the GPR 125 4T 4V not only looks the part but also delivers a thrilling experience on the road. At the heart of the GPR 125 lies a robust single-cylinder, four-stroke engine with a displacement of 124.76 ccm, generating an impressive 15 HP at 9,250 RPM. This power is complemented by a 6-speed gearbox that allows for seamless acceleration and responsive handling, making it a joy to navigate through twisting roads or city traffic. With a compression ratio of 12.0:1 and a sophisticated carburettor fuel system, riders will appreciate the smooth throttle response and exhilarating ride. The liquid cooling system ensures optimal performance, even during extended sessions, while the bike's lightweight build—tipping the scales at just 120 kg (264.6 lbs)—enhances its agility and maneuverability. The GPR 125 is equipped with a range of advanced features that elevate its riding experience. The front suspension boasts a 40 mm upside-down fork, providing excellent feedback and stability during high-speed cornering, while the rear monoshock system ensures a plush ride over varied terrains. Stopping power comes from a sharp single disc brake with a radial caliper in the front and a reliable drum brake in the rear, offering confidence-inspiring performance. The bike's 13-litre fuel tank ensures you can enjoy longer rides without frequent stops, and the electric starter adds convenience for everyday use. **
