The OK-LIGHT radiator was designed for the OK and OK-Junior classes. The radiant mass was designed to allow proper cooling of the OK / OK-J single-speed engine.
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.
A model based on the RS model, but specific for use combined with Honda shifter engines, which are widely used in the United States of America.
Based on the RS model, the RS-V features the “V-shaped” arrangement of the cooling cores.
The overall front width is still 24 cm, but the surface area of the cooling cores exposed to the air is slightly greater.
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.
A model based on the BIG model, but specific for use combined with Honda shifter engines, which are widely used in the United States of America.
Based on the BIG model, the BIG-V features the characteristic ”V-shaped” arrangement of the cooling cores.
The overall front width is still 30 cm, but the surface area of the cooling cores exposed to the air is slightly greater.
