Peter Henshaw's book is of interest to those, who wish to buy a Norton Commando for the first time in their lives. For those, it is probably a help; for accuracy of technical information it wasn't my first choice.

Henshaw's assessment of the technical developments and his account of when technical changes or changes in specification were carried out is far from accurate and contains popular but untrue myths (f.e. the Combat saga), copies mistakes of many other works about Commandos (numbering system of 750s, total number of bikes built), and introduces new ones.

It is probably unfair to critizise a book for somebody one who was professionally involved in Commandos and their spare parts for over three decades. But it is irritating nonetheless when one sees obvious mistakes like "some Mk3s were produced to JPN specification" (that never happened bar the bike that was built and photographed for the Mk3 prospectus)- not to mention a lot of others.
