S14 is the latest version that Birel ART supplies of the specific chassis for the shifter classes, the CRY30, a model that won the 2019 world championship, the title of vice world champion in 2020 and two KZ FIA Karting European Championship, in 2020 and 2021. The beginning of the development of the CRY30, as we know it today, began in 2019, for the international competitions in the KZ class (the most prestigious gear class in the world), and was then offered to the public in 2020 with the identification "S11". This version was followed by the S12, in 2021, now replaced, in fact, by the S14 (with a "dutiful" jump, for superstitious reasons, of the edition with the number 13).

Overall, the presentation is really excellent: the finishes have been managed in detail while the accessories have been designed with a double objective: to offer a good perceived quality but containing the weight and maintaining a marked constructive simplicity. These last two aspects affect both the performance and the ease of use and management of the kart by kart drivers. Up close, then, you can see the absence of imperfections, a signal that, in addition to satisfying the eye, immediately makes it clear how much attention has been paid to the product during the manufacturing processes. The bends of the tubes are all linear, without any apparent deformation, as well as all the machined accessories that show excellent finishes and treatments. The body tubes, which for this model are all 30 mm in diameter and 2 mm thick, are made of chromium molybdenum steel alloy and undergo a specific heat treatment which is part of Birel ART’S know-how (not accessible to us).
