I've done the cast wheels on a couple of Japanese bikes to look like this:
These cast wheels have a machined surface on the outer edges, and a rougher cast surface on the spokes and on the center part where the spokes attach, all covered with powdercoat. If the coating is removed, you can get the two tone look. It's a bit of a chore to do it yourself with paint remover - takes at least two coats, and then it's easy to mask and paint the center section to contrast with the machined edge.
Are the 3-spoke Brembo wheels on my 695 painted, or powdercoated? And are they machined on the outer edges like the Japanese wheels? I've had good luck masking and stripping just the machined outer edge on some Nissin wheels, leaving the original coating on the spokes. I'd like to do this on the Brembos for a black/silver look.
Any suggestions appreciated.
