I Have an MC28 and I wanted an HRC 3 core Radiator, but is impossible to get.....and for those that have one for sale they want to sell it for as much as a used Honda Civic here in the States.
I contacted a company 10 minutes from here called Koyorad, but they only import Japanese Automotive Radiators nothing for bikes. Does anyone have any suggestions where I can get a New High-Performance radiator for my NSR????
