The Gas Gas TXT GP 125 2026 represents the pinnacle for young riders entering the trial world and professionals seeking ultimate lightness. Its 124.8 cc single-cylinder, two-stroke engine provides high torque at low RPMs and smooth power delivery, making it easy to tackle even the most challenging obstacles. Unlike the standard Racing model, the GP version comes equipped with high-end, factory-ready components. These include TECH front forks with friction-reducing Kashima coating, a fully adjustable TECH TJ3 rear shock, and a performance-enhancing Akrapovic exhaust system. At the heart of the motorcycle is a chrome-moly steel frame weighing just 6 kg, designed with a specific flex to provide maximum feedback to the rider. The 2026 model features fresh graphics and black anodized CNC-machined triple clamps, completing its aggressive and professional look. Braktec hydraulic clutch and brake systems ensure consistent performance even during the most precise maneuvers. Weighing only 66.7 kg dry, this machine promises an unrivaled experience on trial courses with its agility and balance.
