Noteworthy introductions to the B.S.A. range, since the last edition of this book went to press, are the 1.74 h.p. two-stroke model and the 4.93 O.H.V., model. Wired-on tyres and internal expanding brakes are now fitted to all models, the round tank 2.49 h.p. two-speed machine has been superseded by the 2.49 De Luxe three-speed model, with taper rectangular-section tank ;all saddles, excluding the two-stroke, now have fore and aft adjustment, a new type, of mechanical pump is fitted, frames have been strengthened (particularly at the head), silencers have been increased in capacity — these represent latest developments. Accordingly, much of the matter appearing in earlier editions has necessarily been revised and largely rewritten in this. I thank my readers for the generous reception they have accorded earlier editions.

BOOK OF THE B.S.A
THE VARIOUS B.S.A. MOUNTS
Thirteen different B.S.A. motor-cycles are marketed, ranging from 1.74 h.p. to 9.86 h.p. - one 1.74 h.p., one 2.49 h.p., three 3.49 h.p., three 4.93 h.p., one 5.57 h.p., two 7.70 h.p., and two 9.86 h.p. The latest addition to the B.S.A,. range is the 1.74 h.p. machine, which is a two-stroke. Incidentally, this is the first time that the B.S.A. firm have made a two-stroke. In a book of this nature specifications are unavoidable, and are here presented in a form suitable for ready reference, in the order of their powers, starting with the lowest-powered machine.

First published in 1924, some later editions covering models up to 1937 omitted the early machines.
