The GASGAS trial engine is proof that the best things really do come in small packages! Thanks to the years of continued development and designed to be compact, light and above all else powerful, the advanced single-cylinder liquid cooled 2-stroke engine features thermodynamic ports, which contribute massively to making it the most competitive power unit in its class. Producing strong and controllable power the engine benefits riders of all skill levels. With optimised mass centralisation the compact engine also aids handling and direction change.
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.
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.
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.
Exclusive to the TXT RACING and TXT GP trial bikes are our patented front and rear brake pads. Manufactured to include magnets on the backing plates, the brake pads remain perfectly aligned, and in position, when wheels are removed, guaranteeing quick and easy wheel removal and reinstallation.
