I have Road King Classic 2012. I purchased UltraCool cooling system because air temperatures in summer in Croatia are about 100-104 and oil in motorcycle before cooling system was about 280-300. After very simple installation of UltraCool cooling system max oil temp. is about 230-235 so the system works absolutely perfect. Aftermarket support service with Earl and Larry works amazing so I recommend this product for everybody who wants to extend life of his bike.
