I had similar shape and size bars called Z-bars on my '59 Triumph back in the day. But that was a long time ago and all I can remember about them is that they made me look cool (well that's what I thought, lol).
Those don't look too apey. Stock BA bars have about a 3" rise so that's only a 4.5" difference. Not like you'd be hanging off them. How tall are you?
But those are nice looking bars. I like the angular look and think they would really suit our bikes.
