Last update: April 24, 2007 
Current number of Manufacturers listed --- 1,320

How many of them ring a bell?

 Unless I consider the source very reliable, I don't add an entry unless it can be verified by at least three sources.
(Which usually conflict with each other in some way, so the verification only means  that it probably did exist.) 
Entries with a ? means the motorcycle has conflicting,  incomplete or suspect information.

AJR England
AJS Was created by the four Stevens Brothers, who started the Stevens Motor Manufacturing Co. in 1899 to build engines and A. J. Stevens & Company in 1909 to produce motorcycles. The AJS came from Albert John (Jack) Stevens' initials. They built their first AJS in 1910 (1911?), a 298cc side valve engine motorcycle. They possibly experimented building motorcycles as early as 1897. They had a semi-partnership with Wearwell motorcycles in 1901 with the production of the Wearwell - Stevens motorcycle and with Clyno Motorcycles for a while around 1910. In 1931 Matchless Motorcycles Ltd purchased the AJS name and manufacturing rights. The brothers then started Stevens Brothers Ltd. in 1932 to produce Stevens Motorcycles. The AJS name later became part of AMC and then when AMC folded it was merged with Villiers to become Norton/Villiers (NV)  the group that owned BSA/Triumph started to fail around 1973 and NV bought them and became Norton Villiers Triumph (NVT).  They built trail bikes using the AJS badge until around 1974, some (or all) using Villiers 250cc Starmaker engines (apparently the "Stormer" trail bikes had engines up to 400cc, I am not sure of the engine maker). At least one model was called the FB-AJAY The FB standing for the initials of Fluff Brown who purchased the company around this time. Today there is an AJS Motorcycles Ltd in the UK that is a importer and dealer, selling mostly ATV's and small cc motorcycles made in China and also spare parts for the Stormer dirt bikes. They sell a street bike badged as an AJS but I am not clear who makes it

It is patented and a new head using this concept could be designed for any engine.

They built a complete motorcycle made to accept a 1500cc Volkswagen engine and used a BMW /2 transmission. The bike looked very much like a R60/2 BMW and was available as a kit or complete motorcycle. They are the best looking motorcycle I have seen that incorporated a VW engine. Apparently Butterfield and Willis had a falling out and a lengthy court battle ensued over the rights to the motorcycle and Willis won. Willis used a badge for them that said "Willis 4's"  it resembled the BMW badge so closely that BMW threatened legal action.. Willis died shortly after. Approximately 100 were built. see picture
