How can I make my wheels to look like this?
I'm gonna go out on a limb here and assume the B4 wheels are made like most of the rest of the Suzuki line, including the bigger Bandits. If that's the case, the center of the wheel is rough cast, including the center of the rim where the spokes attach, and the outer parts of the rim are smooth. If that's the case, all you have to do is apply paint stripper to the smooth parts to remove the paint and you'll end up with a fairly shiney surface. With some extra polishing work, you can make 'em shine almost like chrome.
This one (mine) has the edges just stripped and the natural finish left alone (because I'm too lazy to put in that much effort on the polishing for just a little bit more shine).
This one was stripped completely and had the center powder coated to match the bike and the rim polished to a bright shine:
