Check the Wild1's if you want to kep your existent risers (1") if you're up for putting a little extra cash and want some real cool thicker apes, check out www.carlinidesign.com they have some awesome apes and thay carry the increased diameter risers (1.25" and 1.5"), good luck.
I second that. Carlini makes a good product. I have their 16" tall 1.5" diameter gangster apes and couldn't be happier. They look perfect for my bike. I'll bet they'd look pretty sweet on yours, too.
The Carlini Gangster apes is where its at as far as style. I recently installed the Wild1 Chubby bars on mine, and I do love em, but those Carlinis are badass.
