Brough Superior 1000 1930-39
Brooklands is now but a memory to some
motorcyclists—and only a legend to the vast majority who, like the author, have
never seen a race meeting there. The famous concrete bowl at Weybridge, Surrey,
was responsible for a lot of development of British machines—and also
responsible for the development of a lot of mounts designed just for record
The outer circuit lap record was, of course, the
"ultimate" for a small band of riders, headed by Noel Pope, in the immediate
pre-war years. He acquired a very famous Brough Superior, a "blown" 1,000 c.c.
monster built at the end of 1930 for E. C. E. Baragwanath who then won
innumerable events with it in sidecar trim. When "Barry" used it an "8-50" model
J.A.P. engine was employed, with one exhaust port facing forwards and one back,
at that time the latest product of the J.A.P. factory at Tottenham.
Pope dispensed with the sidecar, swopped the
engine for an "8-80" type (both were 80 mm. x 99 mm. o.h.v. 998 c.c. Vee-twins)
that in unblown form produced about 80 b.h.p. With the blower on he had a
fantastically quick device, and on July 4, 1939, he took his rigid framed
monster round to record 124-51 m.p.h.—destined to be the fastest ever
two-wheeler lap of the track. He was timed at 137 m.p.h. over a flying
half-mile, a truly remarkable performance in view of the track's extremely bumpy
The machine still exists today, in the hands of
Vintage Club Founder C. E. Allen, who has rebuilt it to the trim in which
"Barry" first made it—when it would do over the 100 m.p.h. mark, with sidecar!
