This is the go-to book for anyone repairing or restoring a Norton Commando. If I were to entrust a Norton Commando re-build to a professional and couldn't give the job to Norman White himself, I'd want to know that whoever carried out the work had studied this book.
Whilst there are many glossy marque “manuals” published, some of which give the impression of being quick “cut-and-paste” compilations by authors who have never even ridden the bike, this excellent and well-written book is in a different league. Highly recommended, by a former Fastback owner.
