Handlebar clamps

[Gone in 60]

One thing to consider, and it may not be a big deal to you, is that the clamp has an oblong mounting surface on the bottom. Most aftermarket clamps will have a round bottom mounting surface. That means if you used something else, you may have a round clamp sitting on an oblong mounting area on the triple tree. I’d have a problem with that visually but I’m pretty ocd.

Rustoleum Satin Black could be your friend here. I’ve done just as you are looking to, and it came out perfect. Depending on the gloss level of the bars, maybe semi-gloss.
