After four and a half years at 20,000ks my radiator has sprung a leak. I know it is a problem with the superduke but was hoping that mine was good; however, that was not to be. I don't know yet how much for a KTM replacement is but I guess it will not be cheap. I am also in two minds if I want another KTM radiator because I don't think the latest ones are any better. Is there anyone out there that has bought and tried one of the aluminium radiators for China, they are well priced but I am not sure about the fitment.
