Before them my Ducati Monster (air), Ducati ST4s (water), Yamaha Warrior (air), and Honda Shadow (water) also didn't overheat in traffic. That's 95-degrees-sitting-for-an-hour-and-a-half traffic.

Also on my sport bikes I ran water with water wetter and have seen some high temps on the bike while sitting in similar weather and the bikes will eventually start loping and idling funny. Once my coolant temps gets high and I am not moving much I will shut the bike off regardless if it is aircooled or water cooled.
Not trying to be a dick but 95 degree weather and sitting for 1.5 hours with your bike running and not moving or minimal movement and your bike doesn't overheat. I am calling BS on that one

95 degrees with an hour and a half of sitting and your Harley has never went into parade mode (rear cyl shut down), I highly doubt that man sorry. I have been in 90 degree weather bumper to bumper traffic for 40 mins and had my bike go into parade mode.

You can believe whatever you want, but that won't change reality. It simply never over-heated. I checked the oil temperature occasionally and it never went over 280.
On the air-cooled Ducati it's not considered to be overheating until the head temperature reaches 400 (which is about 340 at the oil pan).

I have had CBR 1000s overheat in stop & go traffic, so liquid cooled is not a be all end all. If the MOCO does it, it most likely has to do with some sort of EPA compliance.
OTOH, my XR1200 has oil cooled heads, 92ish hp from stock. I'd be ok with that on a twin cam. Other than the oil cooler, you cant really tell that oil is running up there.
I don't think I'd ever buy a fully water cooled HD....

Heard it from a friend who, heard it from a friend who, heard it from another it is the best way to go....lol. Half of me says yes, the other not. I guess I am with the group that says, keep the air cooled but liken the Liquid and probably buy it if it looks good as a second scoot. Both are good....IMO
