Sitting perfectly between our much-loved 250cc and awesome 300cc trial bikes, the TXT RACING 280 offers the perfect blend of 2-stroke power, weight and maneuverability – the ideal steppingstone for improving riders looking for increased power and super-agile handling. Like all our trial bikes it’s fitted with high-quality parts, Braktec hydraulic clutch and brakes, as well as leading suspension to ensure reliability and a whole lot of riding fun.
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 AND 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-litre 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.
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 TWO-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.
The 2-stroke single cylinder, liquid cooled 280cc engine (272.2cc) features the latest 2-stroke technology and is built to be powerful, light, clean burning, and compact. Sharing much of its architecture with the other bikes within our trial line-up, thanks to years of continued development the cylinder features thermodynamic intake and exhaust ports, which contribute massively to making the engine the most competitive in its class.
CYLINDER HEAD The exact same high-quality manufacturing as goes into each and every one of our trial bikes, the TXTRACING 280 cylinder head features cooling ducts that keep the motor’s temperature down and a specifically calculated internal dome shape to keep power up!
CYLINDER AND PISTON The specially developed high-performance piston fitted inside the TXT RACING 280, together with the 76mm cylinder that features precisely positioned intake and exhaust ports, provide excellent torque and overall motor performance. Attached to the bike via aluminum brackets, the cylinders stays help reduce motor vibrations as well as further strengthening the compact steel frame.
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 Spinning endlessly to ensure all elements of the 2-stroke TXT RACING 280 motor combine to produce smooth, tractable power, the perfectly balanced crankshaft delivers a 60mm stroke, features a closed main bearing made by SKF, and uses a strong, lightweight connecting rod that uses two needle bearings to ease lubrication and increase durability. It also drives the water pump impeller.
CRANKCASE All of the internal motor parts on the TXT RACING 280 are held within our super-strong, light-weight crankcases. Not only are they incredible durable, in housing all moving shafts close to the bike’s center of gravity the design is both hugely compact and aids bike maneuverability and handling.
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.
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.
