G4 350cc Sidevalve machine in sporting trim

Authentic and well-documented example of an early AJS vintage motorcycle
Founded in Wolverhampton in 1909, A. J. Stevens & Co. Ltd quickly established itself as one of Britain’s most technically capable and competition-driven motorcycle manufacturers. Building on the engineering background of the Stevens family, the firm gained early recognition for the quality and performance of its single-cylinder machines, success that was soon reinforced on the world stage at the Isle of Man TT. By 1914 AJS had secured its first TT victory, a result that cemented the marque’s reputation and drove rapid growth both before and after the First World War.
During the early 1920s AJS expanded its range significantly, with 350cc models forming the backbone of production and proving equally suited to sporting road use and competition. Continuous refinement of engines, frames, and cycle parts kept the company at the forefront of British motorcycle design, while demand for its machines remained strong both at home and overseas.
By 1926 AJS stood at the height of its pre-depression success, producing well-engineered and highly regarded motorcycles that reflected nearly two decades of racing pedigree, technical development, and manufacturing confidence.
This AJS G4 is presented in older restoration condition and retains the characterful sporting trim typical of period use, including an open primary drive and slimline mudguards, both entirely consistent with contemporary sporting practice.
The motorcycle has not been run since its purchase in 2008, during which time it has formed part of a private museum collection. As a result, it will require recommissioning prior to use. Importantly, the machine retains matching engine and frame numbers, confirming it as a genuine, factory-paired example rather than a later assembly.
The specification reflects period-style choices rather than modern reinterpretation, giving the bike an honest and authentic appearance aligned with how many AJS 350s were ridden in the 1920s. The older restoration presents with appropriate maturity rather than over-finish, making it particularly appealing to a collector who values historical integrity.
A scarce and correctly numbered example from AJS’s highly respected mid-1920s production, this G4 is accompanied by a current V5C, the original buff logbook, and a selection of period and later photographs showing the machine in use at vintage motorcycle events, further supporting its history and appeal.
