TXT GP 300

The 2025 GasGas TXT GP 300 is the epitome of elite trial riding hardware—a precision-built machine crafted for riders with the highest expectations of balance, control, and power. Boasting razor-sharp factory racing styling and slim profile bodywork molded from ultra-flexible polypropylene, this bike offers unparalleled freedom of movement while standing up to the inevitable impacts of serious trials work. From delicate rock placements to aggressive hill climbs, the TXT GP 300 is engineered to help riders push their boundaries with confidence and finesse. It's a true extension of the rider, melding form and function with class-leading agility.​​

 Bold Powertrain & Smooth Shifting Beneath its sleek exterior lies a high-performance 294.1 cc two-stroke engine that delivers a rich, tractable torque curve—ideal for nuanced throttle control in technical terrain. A refined six-speed gearbox paired with a precise hydraulic clutch ensures shifts that are both crisp and reliable, even under extreme conditions. Starting is simplified with a robust kickstarter, while an optional dual-map capability allows skilled riders to switch ignition curves on the fly for different segments of the course. Every component is chosen to offer riders maximum control over power delivery and responsiveness, frame to finish.
Precision Chassis for Technical Terrain At the core of the TXT GP 300’s handling prowess is a lightweight 25CrMo4 steel central-tube frame that balances flexibility and rigidity to yield instant feedback without sacrificing strength. Suspension duties are handled by high-end Tech forks with premium Kashima coating up front, offering 160 mm of sensitive and adjustable travel, while the rear benefits from a fully tuneable Tech shock linked to a compact swingarm with 174 mm of travel. Together, these deliver confidence-inspiring damping performance, whether you're threading through trees or soaring off ledges. The ergonomics, from wide footpegs to factory-race cockpit layout, are designed for precision and comfort in the toughest of trials environments.
Elite-Level Finishing Touches & Endurance Trail-worthy details abound—from front and rear Braktec brakes equipped with factory-level Galfer discs, including an auto-support rear setup, to lightweight CNC-machined hubs and Michelin X11 tires that deliver unwavering traction over the toughest surfaces. A high-efficiency cooling system with U-flow radiator and electric fan keeps engine temperatures in check without sacrificing mass centralization. The exhaust system is deliberately lightweight, enhancing response while saving weight. Add in Renthal grips, Neken bars, and a durable yet svelte radiator-mount design—and you’ve got a bike that blends race-readiness with rider endurance. The TXT GP 300 clearly sets a benchmark for competition-grade trial performance.
