MOTOR
Built to be compact. Built to be lightweight. Built with the latest 2-stroke technology. These three important attributes combine to deliver awesome performance and guarantee day-long fun! And just like with all of our trial bikes, the TXT RACING 250 motor packs a serious punch, mixing low weight and high performance to ensure a next level riding experience. |
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 it delivers strong, torquey power each and every ride, the TXT RACING 250 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 72.5 mm bore, guaranteeing maximum performance and durability. |
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
A stainless-steel front pipe and rear silencer maximize 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 compact silencer endcap, which reduces the risk of potential damage. What we didn't change is the well-known and loved easy-access design, which allows super quick and simple silencer packing changes, as and when needed. |
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
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 ensure 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 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 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. |
