Some nice images there, beautifully sharp in the right places, well exposed and well captured colour. Seems you got the shutter speed just about right as well. Second shot of Laverty would be my choice of the three, only thing I would say would be to try and place the bike to the left of the frame so that its riding in to the shot, if you know what I mean? Guess its the same idea as rule of thirds, leaving some free space to the right. Always easier said than done when you are trying to pan at the same speed as a bike though :)
