KG is producing and marketing a very high end line of radiators. These products that are handcrafted, handwelded and utilizing a high quality core have been at the top of many international championship and series since the beginning of their utilization by top names and top drivers.
Here a breif summary of what is available, what are their specification and the more indicated use for each one.
RD.450.245KIT 
This is the most common and with the most possible utilization. It comes with the mount, a catch can kit mount, a quality cap and a shade to partialize the influx of air, so you can have more or less cooling according to the outside temperature. It measure 450mm in height, 245 mm in width and 40mm in depth.
RD.450.185KIT (STANDARD) Same as above but with a width of 185mm.
RD.450.300KIT (EXTRA)Same as above but with a width of 300mm. This is very large. Big cooling mass and certainly need to have the space to be mounted. But it is VERYeffective for the kart and engines that do need to have a lot of cooling at the best possible quality-price ratio.
RD.440.280KIT This radiator is the state of the art karting radiator. The core is designed with a different system, where the water does flow horizontally and does much more cooling. The dimension are slightly different, being 440 mm height, 280 mm width. It also comes with mount, catch can kit, cap and shade.
RD.440.300.200 PENTA. This radiator is the well known "Penta" or "Nevada" due to its particular design and shape. As the Maxi above it has the best core available in the market with a high capacity for cooling. The peculiarity here is the shape that allows for extra air flow to go around the radiator and toward the back of the chassis. It does not allow or offer a shade, and it is generally used for KZ shifter engines of the top level that do need high cooling to the high performance they are set up to deliver. THis radiaotor also comes with mount and catch can kit, no shade.
All of the radiators offered with the shade can also be requested without shade. It is however advised to take them with shade as it will come useful at times.
There will be addition on the radiator production and marketing in the future with an even more special production, limited edition of radiator with a complete new system of shading-partializing.
