Pinning the bars makes sense from a leverage standpoint, so does the knurling. What do you pin them with?

 

I put Burley 12.5 on my RKC. No more neck or shoulder pain on long trips.

 

18" Wild 1's
With a one piece top bar clamp good bars will not move. I always replace the stock
riser bushings with harder aftermarket ones. I'm 6' 4" with a low profile seat, seems to work for me.
I just installed a 14" Winvest windshield that fits between the bars, I'll post pics when I get around to it.

 

In Illinois bars over your shoulders are illegal. Saw an article about a cycle wreck and they ticketed the guy for illegal bars. Had never heard of that and looked it up and sure enough it's Ill. law. Now that we have more motorcylce cops they are probably watching this closer than before.

 

Same thing here in Md. 15" over the seat is our BS law. Never been pulled for apes.

 

Here's the run down state by state for those interested:

I have pinned them with both setscrews and rollpins throughout the years. Both work great but I have been using set screws for the last few sets to aid in easy removal when needed.

 

Check out Hot Bike Bager October Issue they take a Road King and put a set of 20" Apes and then put different height guys with a picture to show you how high of a reach to the top of the bars .

Here is the fit guide they came up with
5' to 5'4" 12" Apes
5'5 to 5'8 14" Apes
5'9 to 5'11 16" Apes
6" to 6"2 18" Apes
6'3 to 6"5 20" Apes

The bars they used were Bury Brand
