When I bought my 2008 Road King FLHRC, I needed enhanced cooling for everything from traffic jams, to parades, to veteran funeral processions, and a fan hanging off the side just didn’t seem to fit the bill. I’ve had the original UltraCool on my bike for over 7 years now and I’ve never had a worry of overheating, whether cruising Las Vegas Blvd or enjoying the desert at Run-A-Mucca. Desert heat has shut down my GPS and my phone but not my bike. I just upgraded to the newly designed model just because the new design looked even more efficient and I have no doubt I will be even more impressed than I have been with the original. Be good to your bike and get one of these.
