  • Cutting edge, stylized, racing image GasGas has completely reinvented its great trial icon. The TXT Racing 2019 range with numerous new features is now unveiled before all trial lovers. The first of these, evident to the naked eye, is on an aesthetic level with completely renewed graphics and a markedly 'racing' appearance. All this thanks to the stylization of its lines and the originality of elements such as the new front mud guard, integrated into the fork brace, or the combination of basic colours such as black, red and white in the plastic and the embellishment of parts such as the new aluminium swingarm or the clutch cover. The rear section shows the remarkable changes that have been incorporated in the new GasGas TXT Racing 2019, with the debut of its new swingarm and most of the additional components associated with the rear section. This includes a long list of new features in the rear section, headed by the incorporation of a new more effective brake cylinder, a new disc protector anchored directly to the brake calliper, and a new guide for the rear brake hose, which has a new sprocket protector. In addition to a practical side stand with a new protrusion to facilitate its extension with the sole of the boot, a new chain skid, detachable without the need to undo the swingarm and an easy to assemble chain tensioner that now has even greater protection.
  • Maximum reliability and great performance Often external changes are a reflection of an internal renewal, as in the case of the new TXT Racing 2019, where this season's models adopt highly relevant developments in the engine. If we delve into its heart, we find one of the main modifications of this model: new crankshaft bearings that ensure the correct lubrication of the engine, ensure the hermetic fit of the assembly and, in turn, allow its easy and convenient maintenance from the exterior. The new trial range from the company in Girona will be manufactured in the usual engines sizes of 300, 280, 250 and 125 cc, counting on its compact, light single-cylinder water cooled 2 stroke engines with six-speed gearbox. In addition to the proven reliability and resistance of its engines, new kevlar clutch discs are incorporated in this range with a new spring and new variable preload. In this same section, the clutch cover constitutes one of the remarkable new features of this edition. A cover divided in two parts in order to simplify access and maintenance, and facilitate the removal of the clutch discs, a job that now requires only the simple operation of removing the outer cover.
  • New swingarm and rear section New elements in the rear section in addition to the new aluminium swingarm with its progressive linkage system, include the two-way Öhlins hydraulic monoshock with 174 mm travel and the new anchorage between the swingarm, the chrome-molybdenum tubular chassis and the engine with bearings double sealed to the exterior, which ensure a hermetic finish and provide a perfect balance between stability, traction and the reaction capacity of the rear shock absorber in the most demanding and uncompromising trial zones for riders. An absolute redesign of the swingarm and link that give a new progressiveness to the models of the new GasGas TXT Racing 2019 range, increasing its stability and improving the traction and precision of the rear section.
