A major innovation is the incorporation of a new front fork, Marzocchi, larger diameter (renumbered as 40 mm models and large displacement of 38 mm in the 125 and 200 cc). By increasing the diameter of the bar, proportionally increases the rigidity of the assembly and, consequently, eliminates the possible bending of the frame. the TXT Pro 2004 also adopted a new damper in the suspension later, representing a new tare in confluence with the experience drawn in previous years by official team drivers in the Championship World. The clutch discs are also new, improving their quality to ensure that the surface is slick. to make clutch cover and new housing have changed the original molds, both components giving a better finish.
