The predominance of the data included in this publication was compiled from 1924-1939 service documentation. However, much of that same information is applicable to motorcycles manufactured before and after those dates. For instance, gearboxes manufactured by Albion, Burman, Sturmey Archer, etc. were installed in a variety of earlier and later motorcycles. In addition, many of the motorcycle manufacturers also utilized their proprietary gearbox and clutch systems in both earlier and later models.

This publication also includes a complete listing of titles in the 'Motorcyclist's Library' series. Many of those books expand on the repair and maintenance procedures for other mechanical and electrical components and will be of assistance to owners and restorers of classic, vintage and veteran motorcycles.
