It originated, as the name suggests, with the advent of the OK classes in 2016. A compact, lighter radiator was needed that would marry the philosophy of the OK/OKJ classes, namely simplification in order to reduce the weight and costs of karts. New Line’s response to this requirement is called R-OK.
The precursor of all New-Line Racing production. Indeed, the R was the first model produced by the Italian company in the now distant 1998 and is still one of its top selling products. It immediately established New-Line Racing’s production guidelines: quality and the utmost attention to detail.
It is an evolution of the R model, compared to which it is wider (+ 4 cm). That is why it is favoured in the shifter classes, precisely because the characteristic of the engines is that they heat up more than non-shifters. However, in non-shifter classes, it is used by those in search of maximum performance.
With a width of 24 cm, the NEW radiator is favoured choice in the shifter classes where greater cooling capacity is required. In direct-drive classes, however, it can be used by those seeking for maximum performance.
