Starting from 2025, all CRG chassis in the Racing range will adopt the new fairings called 507/509 which replace the previous 507/508. The new fairings have a design that aims to further optimize the aerodynamics and cooling of some technical components, while at the same time giving the Kart an even more attractive look. The number holder is characterized by various slits to discharge the air flows in the most functional way from an aerodynamic point of view and all the studies conducted have also highlighted benefits regarding the effectiveness of the chassis in the front part. Also new is the front spoiler which is integrated with the number holder and has as its main feature two air intakes at the ends which, in addition to improving the air flow, in the categories with front brakes also contribute significantly to the correct cooling. The new fairings are combined with a sticker kit with renewed graphics, but which maintains the classic CRG livery with the black and fluorescent red colors.
 
The body of this model is made of 30mm chrome molybdenum steel tubes and is particularly suitable for direct drive categories, both International (OK – OKJ), and for the main single-brand trophies such as Rotax, Iame X30 and Rok. The design of the body is conventional and among its strong points it has the ease with which it can be combined with all types of tires (option and prime) and the feeling it offers the driver with simple setup adjustments. The accessories are top of the range and include magnesium rims and accessories, VEN 11b braking system and the new 507/509 fairings. By implementing the chassis with the gear lever and clutch kit, the KT2 model can also be used in the KZ categories if a softer and smoother chassis than the usual 32mm is required, useful for example in track conditions with a lot of grip.
