The J90 model is a chassis registered with the approval number 002-CH-28, starting from the 2022 season. The new FIA Karting regulation, introduced in 2018, stipulates that the new versions will last indefinitely, provided that an annual fee is paid. (To learn more, read “Special | FIA Approvals: What they are, What they are for, How long they last… The Ultimate Guide!”).
CONFIGURATION The chassis is approved for both Direct Drive and Shifter use, without geometric distinctions. The only difference is found in the thickness of the tubes of the frame, which is available in both 2 mm (more rigid and more suitable for the Shifter category) and 1.8 mm (more flexible and more suitable for the stresses of the Direct Drive category).
ACCESSORIES The standard accessories are made of magnesium or 7075 aluminum alloy, depending on the type of application of the component. These are alloys that we can define as more “refined” than classic aluminum and which attest to the highest level of quality offered by the chassis by DR Racing Kart.
