Here at fix it when it breaks, I have a 30yr old sitter that chewed away and/or cracked aluminum radiator hose mounts. Chemically, it expanded this crust and split this hose attachment mounting part. Here is a photo of the sitter and what I went thru to clean things up.
So if there are no leaks, internal veins look clean or built up with crust, the antidote is a 3rd water, a 3rd vinegar, a shot glass or 2 of hydrogen peroxide and let sit for 24hrs, flush and repeat.
Research of the KTM series 1290 'Beast' shows; a poor mounting design and can crack a leak from wheelies coming down. Both share the gas tank lower mount and top radiator mounts and when they compress between the weight of the gas, the frame mount lower holding the bottom radiator, it takes the load and cracks the core.
Other than that, you read between the lines about changing coolant hoses for said litigation. No swap out, cough, no case. More of an ass protector warning(s) peppered inside the FSM.
As far as a technical swap of the core at so many years out makes no sense, if the radiator shows no leaks, or can flow thru the veins and not overheat the engine.
