Nikon D90: 1/125 @ 18, ISO 320

Slowing the shutter from 1/160 to 1/125 can have a dramatic effect as seen in the photo above. Panning allows for a blurred background to give the subject a sense of speed. Although this technique allows for only a small "keeper" percentage due to the challenge of keeping the subject centered during the pan. If you can keep the subject center the resulting image will be tack sharp as seen above.
