Published by Temple Press in 1951 this is the second Edition (first was in 1948). The author, P E Irving was both a successful rider and engineer. The book is about “tuning motorcycles for speed” well illustrated with some interesting adverts ( a passion of mine, period adverts that is, though I am aware of speed, I have done two courses to be aware of speed already and will shortly be doing a third).
The dust jacket is a tad on the scruffy side, but its existence is the reason that the boards are in such good condition, I just love the Lodge advert on the back cover.
