Racer TF on a 125cc Bultaco Sherpa S, ca. 1972, feeling the effects of reduced blood flow to the brain caused by speed. Rooster tail no doubt added via Photoshop; couldn’t possibly be wheelspin.

Racer Jerry on a 250cc Bultaco Pursang, ca. 1971, feeling no ill effects of adrenaline flow to the entire body caused by speed. His plate (competition number 99G) has just been blown off. Rooster tail no doubt removed, via Photoshop, by jealous older brother.
