Most of the bikes I've seen that were built for performance became a thing of beauty as I checked the details. You know what I mean, well thought out with nothing on it that isn't needed. Solid motor mounts, tucked away wiring, all the right fasteners and clamps, good tires, sleek tank, functional forks, nicely routed and correct length cables and a simple paint job are just a few things I look for. You pay enough attention to the details and quality of workmanship and good looks become a natural by product of a performance bike.
