The Twenty-1 Winter model is designed for maximum efficiency but small size, perfect for seasons with low temperatures. Of all AF Radiators, it is the one with the thinnest mass.

The effectiveness of the sloping, low-air-impact top pan was the inspiration for the creation of the Twenty-1 Edition. The volume is calculated for maximum performance in all weather conditions. In addition, the technology of the Twenty-1 line includes a special internal structure of the mass, thanks to which the water circulating inside stays there longer.

This greatly improves its performance by lowering the outlet temperature of the coolant by 2° centigrade more than conventional radiators. The quality of the aluminum used in making the mass of the AF go kart Twenty-1 Winter radiator was carefully chosen to improve the slats’ resistance to impact and increase their longevity.

The anchors for the mounts are molded together with the radiator structure. TIG welds are additional accouterments for increased stability and stress resistance. Like all radiators in this line, the AF go kart Twenty-1 Winter radiator mounts belong to the racing range, the architecture of which has been finely tuned over the years and are equipped with silent blocks. To make sure that the cap is also able to dissipate heat it is made of aluminum machined from billet by CNC numerically controlled machinery to achieve maximum machining precision. The Twenty-1 Winter radiator is sold complete with standard brackets.
