It fits like it was made to measure in the sportster nose. Its only 2 cores but I never had any overheating even when being stuck in long traffic queues in the summer. I do have a good electric fan (12") as I recall. And some 325's have an oil cooler althoughI am not convinced that makes a lot of difference in normal driving.

And I should have added that my side bonnet panels are well louvered meaning there is plenty of chance for the hot air to escape - an often overlooked point.

I think having 4 cores just means greater coolant capacity and hence more able to absorb sudden increases in heat dissipation requirements. I guess it makes only a small difference in normal running.

Cheers, Robin
