Chain-drive twin cams and fitments, fin area and piston cooling jets, crankcases, straight crank pins, bearing areas, reshaped combustion chambers, reworked exhaust, and intake ports and valves that optimize emissions efficiency and power output, single-fire ignition systems, glossy paint, and fast as hell. Pretty maids, all in a row. If these are a few of your favorite things, take a trip to Lower Greenville on any given Sunday. It's like bedlam when the bikers gun their hogs, so this is no place for the weak.
