Identical to the BIG MAX, the BIG-S1 features a water outlet, positioned on the bottom side, directed towards the front of the kart. This decision was made to facilitate the installation of the radiator on karts with Honda shifter engines, which are common in the US.
The width of the radiator core, equal to 29 cm, allows this model to offer some of the best cooling performances that a single radiator is capable of producing. In addition, it is one of the most sought after models technically. This is proved by the curve-shaped water inlet (and outlet), capable of improving the distribution of water over the entire width of the radiator core, in order to best exploit its cooling capacity.
Beyond its technical and performance features, the Big-S1 model clearly represents the attention that New Line Racing places on listening to the different needs of the market, trying to meet the demands of all customers throughout the world.
Further optimisation of the air-flow is achieved by use of a rear deflector as standard, capable of diverting the hot air from the rear tyre and facilitating its outflow from behind the radiator.
In extreme weather conditions, it can be combined with the Supplementary model.
