honestly the OEM bars are best suited for city ride, as they give you a more commited stance on the bike, to go about weaving through the traffic, just like on a sports moto.
There is model called Electra (see RE INDIA web site). Although this model is limited to India, but its handle bar is pretty comfortable, has about 4-5 inches of rise and can be pulled back, to sit straight on the bike for more comfortable cruising, that too without any change in the cables. If this could be matched with lower seat (without the springs), nothing like it :-)
