Looking at swapping my stock bars on my '16 RK for some Chubby's.
I had a RK Custom some years ago that had the same type pullback beach bar
style and I really liked them. I am 6' and like to ride leaning back. Are they very comfortable and which would be the better option????

 

Yeesh. Both look painful to me. But I'm partial to 14" bars.

 

That's a nice looking RK. At 6' tall, you likely have a pretty good "wingspan".

Both are nice bars. The WO508s are not as wide but have more pull back than the WO518s. With more pullback, your elbows are likely to be bent when riding unless you lean way back. Personally, I like my elbows fully extended when riding. The other reason I wouldn't like the WO508s is the increased wrist angle.

I have the HD beach bars which are very close to the WO518s. Just not as much rise. My handlebars are 36" wide, have 2.5" of rise and 14" pullback. I ride with my arms fully extended and I am leaning back. It is very comfortable. I'm 5'9" tall.

Also, with the increased width of the WO518s, you'll be able to make a tighter U-turn before the bars hit your leg.

Here are mine (HD beach bars). Let us know what you choose. Pics of the news bars is always nice too.

 

Agreed
