I also think apes look good on long fork choppers and those bikes made for styling and looking cool not "practical long distance cruising bagger type bikes. I have not ridden a motorcycle with apes but I can't in-vision a long distance day with the blood draining out of my arms and my armpits into the cold in winter or cold rainy days.
I have 14" Apes on my 12 CVO Road Glide, I Just had the 40K service done on the bike. I have done several back to back 650 plus mile days on it. I have rode from Knoxville to Ft Lauderdale FL in the rain on it. Zero Issues, far more comfortable than the stock bars. My hands are 1 inch lower than my shoulders.
My 13 CVO Road King has 14" apes on it also, and 13K miles on it.
So I average 24K a year on bikes. So I guess they are fine for long distance riding, they work good on the dragon also.
