There are two types of new AMV magnesium rims with plasma electrolytic oxidation treatment. The Tiger model has longer spokes and an inner offset which gives more rigidity to the rim, thus being suitable for the more powerful Shifter category. Furthermore, the Tiger rim increases grip, a useful feature when exiting a turn. For the non-shifter category AMV has designed and manufactured the Flangia Piana model which, unlike the Tiger, has no spokes but a full and flat shape in the hubs contact area. Thanks to their design, the Flangia Piana rims give the kart a “softer” driving feel, an advantage to the kart’s smoothness. Both versions have the same section designed to have as little air as possible inside the rim.

The new OXiTECH rims, both in the Tiger and Flangia Piana version, are matte white. This is a shade given by the compact layer of ceramic oxides derived from the plasma electrolytic oxidation process which may not seem very suitable for a racing vehicle like the of a kart. Reality, however, proves just the opposite as the OXiTECH treatment improves the cleanliness of the rim and eliminates the possibility for the magnesium to absorb dirt and for stains to not remain. Furthermore, the layer generated by the plasma electrolytic oxidation process acts as a protection and the rim, even after several tire exchange operations, unlike chromate conversion and painting, does not show any abrasions, looking as if it was just purchased.

Despite being the last point of this article, attention to the environment is one of the main factors behind all of AMV Research & Development. As said, the new OXiTECH treatment implemented by the Italian company eliminates the chromate conversion process used before. A process which involved the use of chromium-6, which is extremely harmful to the environment. The OXiTECH treatment, on the other hand, does not use toxic chemical substances or hexavalent chromium and has virtually no impact on the environment and the overall health.
