Personally, I'd go with Woodcraft.
I got one of the first new-gen Ninja 250Rs off the truck a few years ago and volunteered to bring my bike to Woodcraft's shop nearby in Winchendon, MA so they could measure it for clip-ons they wanted to produce for it.
I got to meet the guys and check out their shop while they took my bars apart and did all their measurements.
Totally dedicated bunch to whom making quality aftermarket parts is priority #1 .
Proudly made in the USA and I doubt you'll find better.
