Any 7/8" handlebars will fit assuming you don't go too radical with the height & width. For example, ape hangers will require longer control cables, brake hose and wires. Small cafe' bars like I've got, leaves you with excess cables, wires and hose which can carefully be re-routed to take-up the slack. If you get something like your typical standard UJM style bars, you should be spot-on.
