TXT RACING 125 2023

The GASGAS TXT RACING 125 is the perfect bike for younger riders to hone
their trial riding skills on. Lightweight and so easy to ride, our
smallest 2-stroke trial bike allows all youngsters and beginners to
build their confidence while having a whole lot of fun! Featuring
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 a
BRAKTEC hydraulic clutch and brakes, the TXT RACING 125 features a
collection of quality components that ensures both performance and

Restyled and red, red, red! What’s really cool about our new 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

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 mounted in the new forged aluminium handlebar clamps, the entire front-end is super stable with a confidence inspiring. The whole front end set-up refines the rigidity and feedback from the front wheel while a new bar pad provides a little extra protection.

Redesigned for enhanced ergonomics while fitting seamlessly within the frame and bodywork, the compact 2.3-liter fuel tank is held in place with just one bolt, ensuring fast removal and quick re-installation.

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 while a new, larger skid plate provides
better protection for 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 are 7.5mm shorter for 2023, to 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 new TECH shock is fitted for 2023 for the highest levels of comfort and, most importantly, delivering rear wheel traction! With easily adjustable rebound damping, everyone can 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 foot pegs have been fully redesigned with an increased surface area closer to the frame. This unique design includes a new fixing bolt hidden inside the frame and allows riders to grip the bike more effectively for considerably enhanced control when compared to previous models. The same tried and tested special micro-casting process is retained for continued low weight and maximum grip.

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 redesigned front pipe and an all-new rear silencer maximizes 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 new style silencer endcap which reduces the risk of potential crash damage. One thing we didn’t change is the well-known and loved easy-access design on the silencer which allows super quick and easy packing changes as and when they’re required.

Release all the torque and power you need with just one finger thanks to our super light BRAKTEC hydraulic clutch! Reliable and designed to ensure even wear, it delivers 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 stronger clutch cover prevents damage from rocks and boot wear while a smoother profile lever provides a more comfortable feel.

Redesigned to be stronger and more efficient, the new kickstarter fires
the bike into the life easily with an assertive kick. Adding further
durability, the new footpeg has a beefed up section where the kickstart
meets it for improved longevity.

For complete control, trial specific BRAKTEC brakes are fitted with the monoblock 4-piston caliper and 185mm NG waved front disk delivering unrivalled performance and accurate braking in all conditions. Together with a 2-piston caliper and a 150mm NG waved disk 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 for 2023 with a redesigned fan that increases air flow and reduces sound. And with the radiator neatly tucked away between the new 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.

New 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.
