The GASGAS TXT RACING 125 is, without question, the best trial bike for beginners and youngsters to hone their skills on. But make no mistake, our smallest, and lightest 2-stroke model is super modern and a whole lot of fun to ride! Delivering controllable, revvy power, the 125cc motor has a smooth yet strong torque curve, ideal for helping riders find grip while tackling any obstacle. With class leading suspension, selectable engine maps, and Braktec hydraulic clutch and brakes, the TXT RACING 125 features quality components all chosen for their performance and reliability.
BODYWORK
New year, new look. Our fresh graphics certainly make a statement, ensuring the GASGAS TXT RACING 125 stands out from the crowd. The new design is applied to slim, smooth, and ergonomic bodywork that allows you to get into all kinda shapes as you clean the gnarliest of sections. It's likely that you'll hit the deck from time to time too, which is why all GASGAS bodywork is made from a special blend of Polypropylene. What's so special? Well, it's super flexible and will return to its normal shape even if it's bent more than 180 degrees!
AIRBOX
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.
HANDLEBARS & GRIPS
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.
FUEL TANK
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.
FRAME
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.
CNC MACHINED TRIPLE CLAMPS
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.
TECH FORKS
To ensure our TXT RACING trial bikes provide you with best-in-class performance, we fit a TECH shock that can be adjusted in various ways to suit your style and ability. By fine tuning the pre-load, compression, and rebound, you can create a personalized set-up for maximum comfort and amazing rear wheel traction.

MOTOR
Compact, light, and powerful. If you didn't already know, the TXT RACING 125 motor is by far the most competitive, and rideable in its class. Our engineers have never stopped developing the little 125cc 2-stroke motor either and the current generation delivers its power in such a way that it suits all skill levels. Sharing much of the same architecture as the larger capacity GASGAS trial bikes, the motor not only gives riders smooth power, but the design also aids handling.
CYLINDER HEAD
The little TXT RACING 125 cylinder has specifically designed intake and exhaust ports, which, when used with a forged piston, delivers 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 frame flex.
CYLINDER & PISTON

CARBURETOR
Giving our 2-stroke motors all the fuel they need for a wide spread of smooth, strong power is the KEIHIN PWK 28mm carburetor.
KICKSTARTER
A strong and reliable kickstarter is designed for one thing only - to make sure starting the bike is quick and easy. Okay, that was two things...
BRAKTEC BRAKES
For 2025 we've taken the braking performance of our TXT RACING range up a notch as each bike is now equipped with the same GALFER disks that you'll find on our TXT GP bikes. Up front you'll find a 185mm floating waved disk with a 4-piston BRAKTEC caliper while at the rear there's a 150mm solid waved disk with a 2-piston BRAKTEC caliper. The rear disk also complies with FIM regulations so this bike's good to go at any event.
FAN AND RADIATORS
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.
WHEELS
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.
