MOTOR
Development never stops with the TXT GP 250 motor. Designed to be light, compact, and offer the best power delivery to suit riders of all abilities, our engineers strive to make the best 2-stroke trial motors on the planet. Already packing a serious punch, the cast aluminum cylinder head improves combustion and contributes to a constant running temperature for guaranteed day-long fun! |
CYLINDER HEAD
Our engineers are always looking at ways to get more performance from all of our motors. From their findings, the cylinder head on the TXT GP 250 has been revised for improved combustion and features cooling ducts to ensure constant running temperatures at all times. |
CYLINDER & PISTON
To produce the most usable torque, the 72,5 mm cylinder bore features specially designed intake and exhaust ports for best-in-class performance. Inside, the forged piston is finished with a special coating for maximum performance and extended durability. Connecting the cylinder to the frame is a low weight, aluminum bracket, which reduces vibration from the motor and plays a vital role in the stiffness of the overall chassis structure. |
CARBURETOR
Giving our 2-stroke motors all the fuel they need for a wide spread of smooth, strong power is the Keihin PWK 28 mm carburetor. |
EXHAUST SYSTEM
The MY24 GP models feature a new, high-performance exhaust pipe made of extra-light titanium by the renowned manufacturer AKRAPOVIC, developed in close collaboration with the GASGAS Factory Team. It reduces the weight by (350gr weight reduction = 45%) and provides an extra bit of bottom end performance. |
TRANSMISSION
The lightest gearbox of any trial bike on the market and another patented GASGAS part! The 4/6 system allows riders to select from six gears when there are only four gears on the internal transmission shaft. It's this kind of tech that just shows how advanced the TXT GP bikes are, especially as the gearbox is low in weight and the unique design allows for super compact crankcases. |
CRANKSHAFT
Perfectly balanced to deliver optimized inertia, the TXT GP 250 crankshaft is precisely positioned within the crankcases to ensure riders can rely on instant power and enjoy a super agile ride. Key to the motor delivering great traction, it also helps give the bike its much-loved, agile handling. To increase durability, we use a closed main bearing made by SKF with the strong connecting rod that uses two needle bearings for durability. |
CRANKCASE
Designed so that the internal parts and shafts within the motor are carefully positioned to boost the bike's overall handling characteristics, the gravity casting process used to make our crankcases ensures they are super lightweight and extremely tough. Ensuring an improved seal, we use a central locating pin and a central seal. Also, the clutch cover includes the clutch master cylinder, further highlighting the overall compact nature of the motor. |
CLUTCH
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. |
