TXT GP 250

The 2025 GasGas TXT GP 250 redefines the standard for mid-displacement trial bikes, delivering elite-level performance in a machine that’s both nimble and confidence-inspiring. With its sleek, low-slung bodywork molded from ultra-flexible polypropylene and vivid factory-style graphics, it offers unmatched agility and resilience in tight technical sections. Built for riders who demand the perfect balance between precision and power, this lightweight design allows for seamless body positioning and control during the most intricate maneuvers, letting you push boundaries with complete confidence.​​

 Engine Precision & Custom Control Under the surface sits a refined 247.7 cc two-stroke powerhouse, engineered for a smooth yet engaging power delivery. A newly redesigned die-cast cylinder head improves cooling and lets riders install optional high-performance inserts, enabling customization of throttle response to match riding style. The revised six-speed transmission offers seamless, durable shifting, while the responsive hydraulic clutch ensures effortless control at your fingertips. Every element harmonizes to deliver a ride that’s responsive, adjustable, and highly rewarding—whether you're creeping over logs or powering through technical climbs.
Precision Chassis & Balanced Suspension Built on a lightweight yet sturdy 25CrMo4 steel central-tube frame with aluminum front hangers, the TXT GP 250 combines feedback-driven rigidity with enough flex to keep the ride feel grounded and intuitive. Suspension is handled by premium TECH forks, complete with a Kashima coating and 174.5 mm of finely tunable travel, backed by a fully adjustable TECH TJ3 rear shock. Together, they provide shock absorption that’s both sensitive and supportive, delivering exceptional feel through rough terrain. CNC-machined hubs help shed front-end weight without losing strength, while the entire chassis encourages precise lines and unwavering confidence
Elite-Level Features & Rider-Focused Design This bike stops on a dime with FIM-approved Galfer brake discs front and rear, paired with cutting-edge Braktec hydraulic brake calipers for instant, feather-light modulation. The chassis is completed with race-grade amenities like CNC-machined triple clamps, Michelin X11 trial tires for relentless grip, and a top-drawer Akrapovic exhaust system that’s both lightweight and power-enhancing. Designed to give committed riders maximum precision, durability, and on-sight confidence, the TXT GP 250 stands as a benchmark in modern trial bike design.
