BODYWORK

Minimalist. Lightweight. Durable. As well as giving our bikes a distinctive, modern and super-slim look the bodywork of all GASGAS trial bikes ensures riders feel comfortable and confident during every ride. And because no rider goes more than a few weekends without a fall, we use Polypropylene when injection molding our plastics, which doesn't mark when bent more than 90 degrees. All front mudguards feature an integrated fork brace.

AIRBOX AND AIR FILTER ACCESS

Our airbox has a patented design! Much more than just the place Twin Air filters live, it also provides structural benefits allowing all our trial bikes to be super slim. Maximum airflow ensures all motors deliver instant power whenever needed.

HANDLEBARS & GRIPS

Strong, lightweight tapered handlebars made from high-quality aluminum and fitted with Renthal grips are standard to all of our trial bikes. Connected to CNC machined triple clamps via forged aluminum handlebar clamps, the bars ensure stability and complete rider control.

FUEL TANK

Fully integrated into both the frame and bodywork, our 2.3-liter fuel tank is so compact it almost doesn't exist! Featuring a simple removal system, it feeds the Keihin PWK 28mm carburetor that in turn ensures all 2-stroke motors receive the fuel they need to deliver a wide spread of smooth, strong power.

HANDLING

HANDLING

FRAME

We like to build our frames strong, out of chrome-moly steel. Tubular, 1.5mm 25CrMo4 chrome-moly steel to be exact! Robot cut and laser welded to ensure precision, toughness and long-lasting durability, they provide precise rider feedback and importantly highly effective energy absorption, too. Weighing just 6kg, all frames are finished with a tough red powder coating.

CNC MACHINED TRIPLE CLAMPS

They look great and they're light! And they ensure front-end stability and guarantee precise handling. Our 35mm offset, black anodized CNC machined triple clamps deliver the highest-quality and a factory look.

TECH FORKS

Smooth and progressive to ensure our entire trial range offers the very best handling. The 39mm low friction TECH dampers fitted to all of our trial bikes feature a left side fork that has an adjustable spring together with an End Stroke adjustment function to avoid bottoming. The right-side fork takes care of the rebound adjustment while a 160g aluminum front wheel axle ensures maximum front wheel confidence at all times.

REIGER 2-WAY SHOCK ABSORBER

Previously only found on our top specification TXT GP models, REIGER rear shock technology is now also fitted as standard to the TXT RACING line-up in Europe. The well-known Dutch company ensures the highest levels of performance, comfort and, most importantly, maximum rear wheel traction. With adjustable damping riders can change the behavior of the shock to suit their taste.

SWINGARM

Ready to take those big rear wheel hits, our hollow, one-piece cast aluminum swingarms are both slim but also super solid. Improved for 2021 and developed together with our vastly experienced manufacturing partner, we've increased the already proven rigidity to ensure additional stiffness, reliability and perfect flex behavior.

MOTOR

MOTOR

MOTOR

Built to be compact. Built to be lightweight. Built with the latest 2-stroke technology to ensure awesome performance and guarantee day-long fun! Like all of our trial bikes the TXT RACING 250 packs a serious punch, mixing extremely low weight and high performance and delivering incredible overall agility.

CYLINDER HEAD

It's a simple looking part but the exact shape of the TXT RACING 250 cylinder head plays a significant role in ensuring rider-friendly power that can be used to tackle the toughest sections. Ensuring the best engine performance, the cylinder head features cooling ducts to keep temperatures down.

CYLINDER & PISTON

Ensuring the TXT RACING 250 delivers strong, torquey power each and every ride, it features a professionally engineered cylinder and piston with specifically designed intake and exhaust ports to make the motor the best in its class. A high-performance forged piston is fitted into the 72.5mm bore, guaranteeing maximum performance and durability.

CARBURETOR

Equipped with a Keihin PWK 28mm carburetor that ensures the motors receive the fuel they need to deliver a wide spread of smooth and strong power.

TRANSMISSION

The lightest transmission 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, they reduce weight and allow for super compact crankcases.

CRANKSHAFT

The TXT RACING 250 crankshaft is key to the motor delivering great traction as well as helping give the bike it's much-loved handling. Perfectly balanced to deliver optimized inertia, its low weight and positioning within the crankcases ensures riders can rely on instant power and enjoy a super agile ride. To increase durability, we use a closed main bearing made by SKF with the strong aluminum connecting rod using two needle bearings.

CRANKCASE

Designed so that the internal parts and shafts within the motor are carefully positioned to boost the bike's overall handling characteristics, the high-pressure die-cast process used to make the crankcases ensures they are super lightweight and extremely tough. Also, the clutch cover includes the clutch master cylinder, further highlighting the overall compact nature of the motor.

EXHAUST SYSTEM

The stainless front pipe and rear silencer are essential for maximizing the performance of our 2-stroke trial motors. Additionally, they also reduce overall weight to ensure the very best handling as well as slim ergonomics. The rear silencer uses high-quality fiber packing, key to delivering maximum torque and power delivery. The removable plastic endcap means the packing can easily be changed.

CLUTCH

One-finger is all it takes to control the power of our trial bikes, thanks to the compact hydraulic clutch. Allowing riders to build revs and deliver exact amounts of power to the rear wheel, the reliable, high-quality system also guarantees even wear, near maintenance-free operation and perfect action on every ride and in all weathers. Consisting of 3 Kevlar friction plates, 2 steel plates and a Belleville spring system it guarantees perfect operation each and every time.

BRAKTEC BRAKES

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 is used together with a 2-piston Braktec system and a 150mm NG waved disk. The rear brake system features patented magnetic brake pads, which stay open when the wheel is removed. Pretty neat, right!

INTEGRATED COOLING SYSTEM, FAN AND RADIATORS

We squeeze a lot of cooling technology into a very small space on our trial bikes, essential for ensuring our motor's stay cool and riders get the very best 2-stroke performance. Using an aluminum radiator together with a waterproof electric 115mm fan, a thermostat then ensures a stable and constant coolant temperature.

WHEELS

We use a simple but effective recipe when making our trial wheels. Mix CNC machined hubs with lightweight spokes and zinc plated steel nipples and connect them to high-strength aluminum rims by Morad! The result is super strong wheels that ensure an ultimate combination of strength, performance and reliability. A new lightweight aluminum front axle saves 285 grams improving the lightweight feel of the front end.

TYRES

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

IGNITION / ELECTRICAL SYSTEM

Key to keeping weight down on all of our trial bikes is an ignition and electrical system that needs no battery. Also fitting all of our bikes with a map switch as standard, riders can select between 2 ignition curves based on weather, terrain type and rider preference. Both the Engine Control Unit (ECU) and ignition coil are specifically positioned to be well protected and out of sight.
