I don't know what those are but I also doubt they would be used for motor pacing. In addition to what Ted has mentioned, I think that most purpose built motor-pace bikes at that time did not require the rider to bend over in such an aerodynamic position. After all, the motor was parting the air for the racer and it was really important to be looking up in order to see ahead and to gauge the distance between the bike and the motor.
At least, that's what I surmise when I see old pictures of
motor paced events.
