Not for the faint hearted, the 300cc 2-stroke is built to conquer the toughest sections and take on the toughest challenges head on. With impressive manoeuvrability, low running costs, leading suspension, a strong and reliable gearbox for precise shifting, as well as a hydraulic clutch and brakes from BRAKTEC, the TXT GP 300 truly does deliver serious trial performance.

BODYWORK

Slim, smooth, and ergonomically awesome! Just what you want bodywork to be really, letting you get into all kinda shapes while you're out there cleaning the gnarliest of sections. It's likely that you'll hit the deck from time to time which is why all of the bodywork is made from a special blend of Polypropylene. What's so special about it? It's super flexible, meaning it returns to its normal shape even if it's bent more than 180 degrees!

FRAME

The TXT GP frame retains its well-known flex and strength qualities! Our engineers have taken the latest generation TXT GP trial frames to the next level, ensuring improved rider feedback. Tubular, 1.5mm 25CrMo4 chrome-moly steel is used simply because it's the best material for delivering optimal stiffness combined with low weight. Each frame is created using advanced manufacturing techniques, with assembly handled by robots that laser weld all the connecting pieces together. Weighing just 6kg, the frame is finished with a robust GASGAS-red powder coating while a large skid plate protects the engine, lower frame rails, and linkage. 

MOTOR

The big one in our trial bike line-up! The TXT GP 300 motor is designed to be light, compact, and deliver the best power delivery to suit riders of all abilities. Thanks to ongoing development, it's safe to say that our engineers have made the best 300cc 2-stroke trial motor on the planet with this one. Already packing a serious punch, the cast aluminum cylinder head improves combustion and contributes to a constant running temperature for guaranteed day-long fun!
