From Modern Mechanix:
"WHEN J. S. Wright, present motorbike record holder, makes an attack on his 150 m.p.h, record established last year, he will ride a machine which represents the last word in streamlining. To such an extent are the streamlining principles carried out that certain parts of the cowling were built with the rider on the machine, much as a tailor fits a suit to a customer. The power of the racing motor has been boosted to deliver well over 100 h.p. by the use of a supercharger, and it is expected that this motorcycle will reach a speed in excess of 170 m.p.h."
