I would like to put beach bars on my rk classic.They look cool as hell for that particular bike but do they function well on corners and such?

 

That's their only drawback, slow corners can be a real bitch unless you've got arms like an Orangutan!

 

Tight corners can be a touch difficult, but not impossible. I have beach bars on the 1980 FLT that I just sold... I also had a bunch of 2000 Road King parts on it. It really looked like a Shovelhead Road King.

The comfort of the bar position for me far outweighed the funkiness required for slow, tight corners. It wasn't really all that bad, but it did take a little stretching every now and again. Backing up can be a bit tight too... The close bar, might get tight against your thigh, kinda thing.
