you have also picked up colour from the painted floor refelcting on the bike the grey has probably toned down the bikes colour and you can also see the yellow line reflected, add that lot to the white balance and the use of the flash has more than likely contributed.

i think you would have a lot of truble repeating it in daylight to be honest, maybe in a studio lighting conditions. or play on photoshop with hue etc.etc.
