Features & Benefits




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! 


There aren't many bikes that have an airbox with a such a clever design, but ours do! Not only does it house the top-quality Twin Air filter, but the overall structure also plays a vital role in allowing our trial bikes to be super slim. With easy access, filter changes are super easy with just one bolt securing our filters. 


Restyled specifically for the TXT GP models and red, red, red! What's really cool about our fresh new graphics is that they're applied into the slim bodywork during the production process, which make them super durable. No peeling, no scratching, just a long lasting, vibrant appearance for a super clean look at all times.


Strong and lightweight tapered NEKEN handlebars are made from high-quality aluminum and fitted with Renthal grips for comfort and control. A unique bar pad design, specific to the TXT GP range, protects you from heavy impacts on the bars. Completing the controls and for a factory finish, the clutch and front brake master cylinder caps are anodized in our favorite color - red! 


Redesigned for enhanced ergonomics while fitting seamlessly within the frame and bodywork, the compact 2.4-liter fuel tank is held in place with just one bolt, ensuring fast removal and quick re-installation.

Features & Benefits




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. 


There are some very special triple clamps fitted on our GP bikes. CNC-machined from aluminum specifically for the TXT GP models, they reduce a little weight without compromising strength or stability. They're finished off with black anodizing to match the GASGAS Factory Racing trial bikes! 


Smooth and progressive. Exactly the front fork action you need when tackling the toughest sections! The 39mm, low-friction TECH forks are finished with a premium KASHIMA coating on the inner tubes to maximize sensitivity. Inside the left leg is a progressive spring and preload adjuster, as well as an 'End Stroke' adjustment function to prevent harsh bottoming. Over on the right leg, compression and rebound can be fine-tuned for a personalized set-up. Both outer tubes are anodized in black for a cool finish, highlighting the premium quality of the TECH forks. 


The GP models are fitted with a high-end shock absorber made by the renowned manufacturer TECH. For MY24 it features a large reservoir in order to provide better heat stability for more consistent shock performance even under the toughest conditions.


Slim, super-solid, and super-low in weight. It's cast from a single piece of aluminum and manufactured with proven rigidity and optimal flex for soaking up the biggest of rear wheel hits with ease. A sandblasted finish offers impressive scratch resistance to maintain it's cool appearance.

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!


Our engineers are always looking at ways to get more performance from all of our motors. From their findings, the cylinder head on the TXT GP 250 has been revised for improved combustion and features cooling ducts to ensure constant running temperatures at all times. 


To produce the most usable torque, the 72,5 mm cylinder bore features specially designed intake and exhaust ports for best-in-class performance. Inside, the forged piston is finished with a special coating for maximum performance and extended durability. Connecting the cylinder to the frame is a low weight, aluminum bracket, which reduces vibration from the motor and plays a vital role in the stiffness of the overall chassis structure. 


Giving our 2-stroke motors all the fuel they need for a wide spread of smooth, strong power is the Keihin PWK 28mm carburetor. 


The lightest gearbox of any trial bike on the market and another patented GASGAS part! The 4/6 system allows riders to select from six gears when there are only four gears on the internal transmission shaft. It's this kind of tech that just shows how advanced the TXT GP bikes are, especially as the gearbox is low in weight and the unique design allows for super compact crankcases.  


Perfectly balanced to deliver optimized inertia, the TXT GP 250 crankshaft is precisely positioned within the crankcases to ensure riders can rely on instant power and enjoy a super agile ride. Key to the motor delivering great traction, it also helps give the bike its much-loved, agile handling. To increase durability, we use a closed main bearing made by SKF with the strong connecting rod that uses two needle bearings for durability.


Designed so that the internal parts and shafts within the motor are carefully positioned to boost the bike's overall handling characteristics, the gravity casting process used to make our crankcases ensures they are super lightweight and extremely tough. Ensuring an improved seal, we use a central locating pin and a central seal. Also, the clutch cover includes the clutch master cylinder, further highlighting the overall compact nature of the motor.


The MY24 GP models feature a new, high-performance exhaust pipe made of extra-light titanium by the renowned manufacturer AKRAPOVIC, developed in close collaboration with the GASGAS Factory Team. It reduces the weight by (350gr weight reduction = 45%) and provides an extra bit of bottom end performance.


Release all the torque and power you need with just one finger thanks to our super light BRAKTEC hydraulic clutch! The reliable system is designed to ensure even wear for smooth operation and exceptional performance at all times. Consisting of three Kevlar friction plates, two steel plates, and a Belleville spring design, hours and hours of maintenance free riding is guaranteed. 

Features & Benefits




A reworked kickstarter guarantees improved strength and reliability while the reworked shape of the starter finds an optimal final stop on the footpeg.


High-performance BRAKTEC braking systems that are specifically designed and built for trial use ensure our bikes have more than enough stopping power. Giving riders a controlled action for complete confidence, a front monoblock 4-piston caliper with a 185mm NG waved disc handles things up front. The rear brake system is a little bit special. Not only is a specific, 150mm and FIM-regulated NG waved brake disc used, but the 2-piston BRAKTEC caliper features patented magnetic brake pads, which stay open when the wheel is removed. Pretty neat, right! 


To improve comfort on the bike, the footrests have been fully redesigned with an increased surface area closer to the frame. This unique design allows riders to grip the bike more efficiently, which considerably enhances control when compared to previous models. The same tried and tested special micro-casting process is retained for continued low weight and maximum grip.


The aluminum inverted U-flow radiator has a cooling area of ​​20.4 cm2 and a refrigerant volume of 470,2 cm3, with a mini valve on top of the radiator that opens on 1,2 bars (between 1 to 1,5 bars). The crucial component is a electrical fan with a diameter of 115 mm and optimized blades. Compared to the predecessor it features a reduced noise level and increased air flow.


The wheels on our TXT GP trial bikes are as good as they get. Machined from single pieces of aluminum, the hubs are then anodised black with the GASGAS logo etched onto them for a quality finish. Connecting them to the high strength black rims from MORAD are strong steel spokes and lightweight aluminum spoke nipples in the front, which create a seriously robust wheelset. And looking the business while making sure maximum power is transferred to the rear wheel, we've fitted a black aluminum sprocket and a quality gold chain from D.I.D. 


Michelin's super-light X11 tires connect all our TXT bikes to the rocks, mud, and obstacles beneath them. The best in the business, they feature super-pliable knobbles, which together with low pressures offer exceptional grip. 


HIDRIA ignitions generate stronger power, which stabilizes idling and creates a cleaner response from the bottom end. Depending on your riding style and weather conditions, the handlebar mounted map switch allows for a choice of two ignition curves, which can be selected for tailored power in every section. 


Giving the TXT GP trial bikes a GASGAS Factory Racing inspired look, the high quality D.I.D 520 DMS gold chain looks the business and offers impressive longevity. Our pro riders have put this chain to the test with excellent results, which is precisely why it can be found across the entire TXT GP range.
