A Brief History of AJS

J. Stevens & Co. was established by Joe Stevens in 1856 in Wedensfield, Wolverhampton as a blacksmith works. He and his wife had nine children, all of whom became involved in the business. Inspired by a Mitchel engine of poor performance, by 1897 sons Harry and Joe had built an engine which outperformed the American unit. It was immediately evident where the future of the family business lay, and the Stevens Motor Manufacturing Company of Wolverhampton was established in 1899. They originally built only engines which were installed by other manufacturers, but by 1911 (or 1912) were building their own machines.

The firm of Albert John Stevens was incorporated in 1909 and went on to become one of the pillars of the British motorcycle industry, reaching its peak in the 1920's and 30's. The name is derived from that of one of the four brothers in the firm, Albert John, the only brother with two Christian names.

By 1930 the firm held over 100 world records but like so many others was experiencing financial hardship. In 1931 the Colliers group bought AJS, and in 1938 AMC took over and badge engineered numerous Matchless-based models. Postwar AJS racing machines included the wonderul 350cc 7R (the orginal Boy Racer) and the Porcupine parallel twin. When Amalgamated Motorcycles failed in 1966 the marque was bought by Manganese Bronze Holdings who formed the Norton Villiers group. NV introduced two-stroke competition AJS machines powered by Villiers Starmaker engines, and when that company experienced difficulties in the early 1970s the AJS name was acquired by Fluff Brown who moved the business to Hampshire in 1974.

AJS provided engines to other manufacturers including Clyno.

AJS Model "D" 1914
Just uploading a picture of my model 1914 "D" AJS V Twin which is under restoration. So you can compare mine to the 1914 AJS V Twin that you have on your site from Webbs Auction New Zealand. It is actually a 1915 Model "A" AJS or later. I have also included picture of a 1915 Model "D" and a picture of a 1914 Model D from the 1914 Brochure. as you can see there was a lot of changes between the two models. Regards Dave

AJS 1951 18S Eng. No.16349
Hi, the above bike will have been off the radar for a good 50 yrs as it's been in my shed for 20yrs and my brother in laws for 30 before that. I have decided to breath life back into it before I am too old to kick start it. Before I go buying the "wrong " parts for it perhaps you can help me to find its history so I can make every effort to put it back together as it was at the start?
Warren Sketcher

Your best bet would be one of the AJS specialist sites (ie Jampot, under British Resources), or perhaps try some of the Australian classic clubs.

AJS 18 1949
You may have an answer to two questions. I am looking for an electronic ignition for my AJS 18 1949.
The other is a question of many years. Rudge has a hand emblem. I was told the corresponding slogan is “Honestly So”. I’ve seen no evidence of this. Do you know?
Dan Devine

    According to the Stratford Rudge site, "The open hand superimposed on a bicycle wheel is in fact Whitworth's trade mark & is regarded as "the open hand of honesty". For the ignition, Boyer are available, and if still avail a Dyna 3 would also probably work. The latter I had on one of my machines for 25 years.

AJS Model ?
I am working on an old AJS. Engine # 52 16M 17072
I would like to know the year, and if it is a 350.
Someone has gotten in to the wiring and replaced some of it with black wires, which are now dis-connected. No battery, and the diagram I have in an old book doesn't make it too clear.
Can you help me, Please, I also have a 1970 Triumph T120R, 1st prize winner for best custom bike.
Thanks, Mack.
Mack Sinclair
Pine Bluff, Arkansas

The 16M is a 350, and the equivalent Matchless model is all but identical.

  • The 250 appears to have the same pads which are fitted to the larger models. See gallery. No information on centre stand at present.

AJS 7R3 1954 and Porcupine 1954

Hello dear Aussies, Shocked to see that you list my father (Rod Coleman) as an Ozstraylian.....when he is of course, a NEW ZEALANDER. Can you please correct this rather large mistake - Thank you. Kind of like forgetting Phar Lap was a New Zealand horse......or forgetting the cricket under-arm bowling incident.......ah, I could go on all day. Cheers.
Carl Coleman
Taupo New Zealand

Thank you for your quick reply. As Rod's son, I can definitely confirm Rod as being a Kiwi. Born 19 June 1926 in Wanganui - Roderick (Rod) William Coleman. AJS factory rider from 1951 through 1954. First Kiwi to win at the Isle of Man - 1954 Junior TT aboard an AJS 7R3 (3-valve engine) - also first Kiwi to win at Bathurst (both 350 and 500 TT races), in 1954. After retiring from GP racing at the end of 1954, Rod returned to NZ to concentrate on business. Initially held the NZ franchise rights for AJS and Matchless, but over time also added Norton, BSA, Triumph, NSU, Montesa and finally Suzuki to the business activities. Was NZ Suzuki importer from late 1959 to Feb 1984, thereafter selling the business to Suzuki Motor Co Ltd - Japan. Definitely didn't have a shop in Sydney, but was close friends with Cornell family (Suzuki importers) plus Mortlock Suzuki owners (in Sydney).

The picture shown on your website incorrectly states 1955, but is in fact 1954, as it shows Rod aboard the AJS 7R3 (#33) upon which he won the IOM Junior 350cc TT.

Always willing to help out our fellow motorcyclists, especially our Aussie cousins.

Kind regards
Carl Coleman.

AJS, Matchless any
I am interested in the artwork side of AMC. My grandfather Arthur Walkley founded the company Walkley Hodgson Ltd. in 1936. Later known as Commercial Publicity Ltd. which was the sole advertising agency for Associated Motorcycles of AJS and Matchless. I have a couple of first proof copies which have come down through the family but I am interested in further artwork of the company from 1936 1960 when the company ceased trading. Thought this site might be a good place to possibly find some answers.

yours sincerely
Phil Walkley

Most Beautiful Motorcycle Ever Built
Many years ago (I'd say the mid-50s) as a boy growing up in Arlington, VA (USA) I would walk several miles over to where someone often had what looking at your pictures appears to have been an AJS 18S or similar model. I would stand and stare at that Motorcycle for what seemed like minutes, but might have been hours)! I thought at the time that it was the Most Beautiful thing I'd ever seen...certainly the Most Beautiful Motorcycle! Well, I'm an old duffer now, retired and not in the best of health, but I wanted to tell you that the vision of that Beautiful AJS has stayed with me all these years...I would remember it often as my life unfolded! While I will probably never see another one in person it was a thrill beyond measure to find your web pages and get a chance to look for and I think find a bike very much like the one of my youth!
Over the years I'd owned a number of motorcycles, mostly BSA, Norton, BMW as well some Japanese models, but I never had one that made the impression on me that the AJS did! Thank you so very much for allowing me to relive that special time of my youth, if only in photographs! Sincerely Yours, Guy D. Ogan, Major, USAF (Retired) Fort Worth, TX

1933 AJS 350
33/B6 153955 engine, 1352 frame
This has been in my cellar in boxes for 40 year. I just mocked it together for some photos. What is shown is all I have of it. It was stripped down I assume for racing?? The AJS gearbox was missing, but it came with a BSA 4 Speed Gear of about the same vintage which I have modified to mount to the AJS frame.
As most of the electics are missing I have a couple of questions. I assume it would have had a battery, but I don't see where it was mounted. Can the dyno run lights without a battery? What is in the center of the instrument panel? Is it supposed to be a horn button?
Is there supposed to be frame members that extend from the rear wheel yokes under the gearbox to the crankcase?

Hard-tail 500 single
I am working on a 500 single AJS, hard-tail of (assumedly) 1949/1950 vintage and would appreciate help de-ciphering the engine number which is - 13999. This number is preceeded by the number 50/18, but stamped almost like a fraction........does this indicate 1950/something?

The first two numbers give the year, 1950, and 18 the model, a 500cc OHV single. Admin.

Thanks for getting back to me so quickly, but unfortunately I don't have any photos. The reason being, I'm a motorcycle mechanic 12 years out of the game and had a bloke I know ask for some assistance with his AJS, being the one I enquired about. Without stretching the friendship, could you possibly point me in the right direction to get some information on some of the standard service items like primary chain adjustment, ignition timing gearbox oil type/quantity etc. I guess I'm really asking for help getting a service manual........cheers, Drew.

motor wanted
AJS or Matchless 1000
I"m looking for a 1000 cc AJS or Matchless Vee Twin motor. Preferably OHV but Sidevalve would do to make a "Special" or complete a rolling frame. Depends on what I find. Year of motor not important but would prefer 1930's to 1940 as most were made in this period.
Any help or leads greatly appreciated.

I have inherited my fathers old AJS model 30CS motorcycle which he bought new in 1956 but because of a growing family and the need for a car he stopped using it in 1960, it is in excellent original condition with 16243 original miles on the speedometer, the colour is pale blue and it has a rev counter, detachable chrome headlamp, alloy mudguards and upswept siamese exhaust system, a mechanic friend of mine spent a few hours checking everything over such as the engine and gearbox oil and after fitting a new battery and spark plugs the machine started and runs very well, I also have all of the original paperwork and sales brochures for the machine, I would be prepared to sell the motorcycle but have no idea of how much it is worth, does anybody know?

I believe your machine is an AJS Model 18 of around 1956 vintage, although I am going on appearances only and cannot verify that from the serial numbers.

Parts wanted
AJS M4 350 sv 1929
Hello, Looking for petrol tank, wheels, gearbox + small parts for this rareness. I have some parts to swap for other M 1929 models, also Matchless parts.

Kind regards, Raimo
Lahti, Finland
Many thanks for your help.
Ajs M4 1929 is very rare, as much I know, there are three examples survived. Only photograph I know about complete bike is from Goulburn Valley Motor Vehicle Drivers Club Inc. I don´t have their permission to use the photo, but you can find it: http://www.gvmvdc.org.au/images/dubphotos/images/1929-AJS-M4.jpg [404]
I have some traditional photos of these parts I already have (frame, girders, engine, oil tank etc.), but I wonder, if they are of any help.

Best regards,

ajs spring twin?
spring twin or jam pot?
i am a little confused, my father had ajs spring twin or is it springer twin? was there a jam pot model?
i think they were around 1965 ish, can you clarify what model they might of been, and cc etc as he always siid when he was alive that if i saw one he wanted another, now i want to see what he craved for, and retrace a route he took to spain and back in the 60s and also the tt.are there any clubs im in the north east .thanks in antisipation John

The terms "Spring Twin" and "Jampot" refer to the rear suspension. the latter being the user-adopted reference to the rather bulky rear suspension units on the early swing-arm models. Spring Twin was, I believe, a factory term for sprung heel models of the post-war era, and will appear in advertising pages listed in the AJS gallery later this year.

AJS 1000cc
Is there anyone who owns V-twin AJS motorcycles between 1928- 1932 who would like to contact me. I have a few and a lot of questions!
I own a lot of AJS Motorcycles. Therefore i am naturally looking for missing parts. For instance i am missing the gastank for the 1931-32 1000 cc. I also wonder if there is anyone who makes the footboards for these big bikes. Where is it possible to get the right kneegrips
of the 1929 pattern (upswept upper part). I need at least 10 pairs. When did the factory change from gas light to electric lighting. Bikes imported to Sweden got equipped with Bosch
lights and magdyno and even a Bosch horn. Does anyone have te adress to the company Or the guy in Tjecoslovakia who make those replika front and rear lights and horns.
