The Twenty-1 Large model is recommended in situations where very high temperatures can pose serious risks. Of all our radiators, it is the one with the largest mass.
The TWENTY-1 Edition was born from the excellent experience of the GOLD Edition, which we have tried to improve by making the sloping profile of the upper tray in order to reduce air resistance but maintain the excellent cooling characteristics.
Our years of experience in the industry enabled us to develop this revolutionary product. It is an innovation over previous models in all respects.
The volume has been calculated to achieve maximum performance even in dry weather conditions.
The Twenty-1 line technology due to its internal structure retains water for longer.
This greatly improves efficiency by lowering the coolant outlet temperature by 2° centigrade more than conventional radiators.
The quality of the aluminum used in making the mass of the AF go kart Twenty-1 Large radiator was carefully chosen to improve the slats' resistance to impact and increase their longevity.
Support anchors 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 supports for the AF go kart Twenty-1 Large radiator belong to the racing range, the architecture of which has been finely studied over the years and equipped with silent blocks.
To make sure that the Blue Edition 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, which is also blue in color.
All these measures allow this model to be a benchmark for all categories, both single gear and non-motorcycle.
