This thing is the ultimate oil cooler I have come across in the 50 + years I have been riding. It looks fantastic, not bulky and over bearing. The lines compliment the bike instead of taking away from it. As far as cooling, there is no doubt I can feel the difference. The bike runs so much better smoother and yes, cooler. And the kicker, it is made in The U.S.A. I don’t think you can find a better product to do the job of keeping your bike safe from oil temperature problems.Well worth the money!
