Our redesigned, slim and ergonomic bodywork allows unrestricted movement for riders who want to perform at their very best. And as we all know, hitting the deck from time to time happens in trial, which is why we've used a special blend of Polypropylene that's super flexible and returns to its original shape after impact, even if bent 180 degrees or more!

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.

Development never stops with the TXT GP 250 motor. Designed to be light, compact, and offer the best power delivery to suit riders of all abilities, our engineers strive to make the best 2-stroke trial motors on the planet. Already packing a serious punch, the cast aluminum cylinder head improves combustion and contributes to a constant running temperature for guaranteed day-long fun!
