Features & Benefits




Restyled and red, red, red! What's really cool about our graphics is that they're embedded into the bodywork making them super durable. The fresh look is applied onto our slim, ergonomic plastics, which ensures unrestricted movements and allows riders to perform at their very best. As all trial riders hit the deck from time to time, all bodywork is made from a special blend of Polypropylene, which is super flexible and returns to its normal 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 to the airbox, filter changes are made quick and easy with just one bolt safely securing the filter in place. 


Strong, lightweight, and tapered Neken handlebars are fitted with Renthal grips for the best in both strength and comfort. With the bars clamped into the handlebar clamps made of forged aluminum the entire front-end of the TXT Racing range is super stable with a familiar feel for a confidence boosting ride, time after time. This provides improved stiffness and better feedback to the rider plus we increased protection by adding a bar pad.


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




Strong, but with just the right amount of flex. That's how we build our trial frames, using tubular, 1.5mm 25CrMo4 chrome-moly steel for exceptional levels of rider feedback! Using advanced manufacturing processes, each one is crafted with laser cutting and robot welding. The end result is frames that are incredibly durable and ensure true trial performance. Weighing just 6kg, all frames are complete with a robust GASGAS-red powder coating. Lateral hangers made of forged aluminium connect the steering head zone with the large skid plate, that better protects the engine, lower frame rails, and linkage.


Super cool and guaranteed to ensure front-end stability! Our silver anodized CNC machined triple clamps not only look the business, but they're incredibly lightweight and play a huge role in delivering precise handling. 


Smooth and progressive for the very best handling, the 39mm low-friction front forks improve the bikes overall agility. To prevent unwanted bottoming, an adjustable spring and End Stroke adjustment can be found inside the left leg, while rebound can be fine-tuned on the right-side fork leg. Connecting the forks and ensuring positive rider feedback from the front wheel is a lightweight, 160-gram aluminum axle. 


Making sure our TXT Racing line-up retains its best-in-class performance across all classes and displacements, a TECH shock is fitted. Delivering the highest levels of comfort and, most importantly, amazing rear wheel traction, with its adjustable rebound damping all riders are able to dial in the shock to suit their riding style and ability.    


Slim, lightweight, and super-strong! Cast from a single piece of aluminum, the swingarms fitted to the entire TXT RACING range are manufactured with proven rigidity and optimal flex, to soak up the biggest of rear wheel hits with ease. 


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

Features & Benefits




Powerful, light, and compact, the TXT RACING 125 motor is the most competitive in the small bore class. Years and years of continual development has created a user-friendly power delivery from the 125cc 2-stroke motor while maintenance costs are kept to a minimum. Sharing much of the same proven architecture as our larger capacity trial bikes, the motor's design not only gives riders the performance they need, but the design also aids handling.


The internal shape of the cast aluminum cylinder head has been specifically calculated and improved to ensure the very best clean running engine performance, as well as featuring cooling ducts that keep the motor at a constant temperature.


The little TXT RACING 125 cylinder has specifically designed intake and exhaust ports, which, when used with the high-performance forged piston, ensures the motor is the best in its class, producing impressive torque and a smooth power delivery across the full rev range. A low weight, aluminum cylinder bracket is used to reduce engine vibrations while also assisting with chassis stiffness.


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 in any trial bike on the market and another patented GASGAS part! The 4/6 system allows riders to select from 6 gears when there are only 4 gears on the internal transmission shaft. Ensuring all TXT RACING bikes are technologically advanced, the gearbox reduces weight and allow for super compact crankcases.  


The magic at the center of the TXT RACING 125 motor! Our engineers perfectly balance each and every crankshaft to ensure maximum inertia and deliver a 54.5mm stroke, allowing the motor to run freely and deliver instant power. To increase durability, we use a closed main bearing made by SKF. Due to its specific positioning with the motor the crankshaft also contributes to the bike's awesome handling. A strong, lightweight connecting rod completes the crankshaft, which also drives the water pump impeller.


We save weight wherever we can to ensure the TXT RACING 125 remains the most competitive bike in its class. That's why the bike's super-compact crankcases are made using a high-pressure casting process, which guarantees incredible strength and durability and keeps weight down. The super-compact design puts all major moving parts close to the bike's center of gravity for incredible handling. Making things even more compact, the bike's hydraulic clutch master cylinder is built into the clutch cover.


A stainless-steel front pipe and rear silencer maximize the power and torque from our compact 2-stroke motors! Both components are low in weight for uncompromised handling yet high in strength for incredible durability. Our engineers also worked on a compact silencer endcap, which reduces the risk of potential damage. What we didn't change is the well-known and loved easy-access design, which allows super quick and simple silencer packing changes, as and when needed. 


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. A durable clutch cover guarantees higher stiffness and a smoother profile lever offers a more comfortable feel.

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.


For complete control, trial specific BRAKTEC brakes are fitted with the monoblock 4-piston caliper and 185mm NG waved front disc delivering unrivalled performance and accurate braking in all conditions. Together with a 2-piston caliper and a 150mm NG waved disc at the rear, the overall stopping power on the TXT RACING range is next level. A smoother profile front brake lever also offers a more comfortable feel. 


The seriously clever integrated cooling system on our TXT Racing trial bikes is further improved with a redesigned fan that increases air flow and reduces sound. And with the radiator neatly tucked away between the aluminum engine mounts, the whole system is well protected from crash damage for continued 2-stroke performance. 


They're built to last. Strength and reliability combine to create high performing wheels that will stand the test of time. With a CNC machined hub connected to the cool, black anodized aluminum rims from MORAD with lightweight spokes, this wheelset is capable of soaking up the hardest of hits. Up front, the aluminum axle is low in weight, high in strength, and plays a huge part in ensuring the front-end has a lightweight feeling. 


Michelin's super-light X11 tires connect all our TXT RACING 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.
