Motorcycles

Joe Stevens, father of Harry, George, Albert John (‘Jack’), and Joe Stevens Junior, was an engineer who owned the Stevens Screw Company Ltd, in Wednesfield, near Wolverhampton. Stevens had a reputation for quality engineering before the company built its first motorcycle in 1897, using a Mitchell single-cylinder four-stroke imported from the USA. Before long, Stevens began making engines, starting off with a better-built version of the Mitchell but the family soon developed their own designs, including parallel-twins and V-twin

s, which were sold as proprietary engines to other manufacturers, including Werner, Wolf and Clyno.

In 1909, after a Wearwell motorcycle fitted with a Stevens side-valve single-cylinder engine won a trophy for a 24-hour non-stop run in 1909, Jack Stevens decided to contest the Tourist Trophy

. A new company, A J Stevens & Co (AJS), was founded, with premises in Retreat Street, Wolverhampton, to manufacture motorcycles and the first model appeared at the Motor Cycle Show in 1910. Its engine, a two-speed 298 cc side-valve, was made to come within the 300 cc limit for Junior machines in the 1911 Isle of Man TT

 races and was slightly larger than the 292 cc used for the proprietary engines. Jack Stevens came 16th on AJS's official entry, one place behind private owner J.D. Corke on an identical machine.

Albert John Stevens lent his initials to the company, but it was a family concern. In 1922 for example, Harry Stevens acted as managing director, George Stevens as commercial manager, Joe Stevens Junior managing the experimental section and Jack Stevens as production manager.

AJS did not contest the 1912 TT as it was busy satisfying the demand for its products, but was 10th in the 1913 Junior. With the Junior limit raised to 350 cc for 1914, the AJS motorcycle had grown to 349 cc, with four-speed gears and chain final drive. AJS won first, second, third, fourth and sixth place in the Junior 1914 Isle of Man TT

Stevens (1914) Ltd, AJS moved to a new factory built around Graiseley House on the outskirts of Wolverhampton. The 349 cc machine (known as the  hp) was most in demand but the company also produced an 800 cc (6 hp) V-twin.

On 3 November 1916, the Ministry of Munitions prohibited the production of non-military motorcycles, and AJS went over to manufacturing munitions, but in early 1917 the Ministry received an order from Russia

 machine. This kept AJS busy until Ministry of Munitions restrictions were lifted in January 1919.

When production of the 350 resumed in 1920, it was much improved. The side-valve engine was replaced by a new overhead-valve design that produced 10 bhp. It also had internal expanding brakes and chain primary drive. Cyril Williams won the first post war 1920 Isle of Man TT

, and Howard R Davies bettered his second place in the Junior by winning the Senior on the same 350 cc AJS. This was the first time a 350 had won the 500 cc Senior TT race. In 1922 Manxman Tom Sheard won the Junior on an AJS, with G Grinton, also on an AJS, taking second.

The 1922 machine was a classic design that would become famous as the ‘Big Port’ on account of its large-diameter exhaust port and pipe (initially 1 5/8 inches, but changed in successive years). The OHV 350 would be the mainstay of the company’s racing efforts until 1927 and in production form (first offered to the public in 1923), was also AJS’s most popular sports motorcycle throughout the 1920s. At this time, the company produced a comprehensive range of other models ranging from 250 to 1,000 cc. These were generally given a model number, plus letter to denote the year of manufacture (for example, E meant 1924, F 1925, G 1926).

In 1929 for example, the AJS range consisted of:
M1 Deluxe 996 cc side-valve V-twin £76/10/0;
M2 Standard 996 cc side-valve V-twin £66/0/0;
M3 Deluxe Touring 349 cc side-valve single £48/10/0;
M4 Deluxe Sporting 349 cc side-valve single £48/10/0;
M5 Standard Sporting 349 cc side-valve single £45/0/0;
M6 349 cc overhead-valve single £54/10/0 (twin port), £52/0/0 (single port);
MR6 Special Sports 349 cc overhead-valve single £62/0/0;
M7 349 cc overhead-camshaft single £62/0/0;
M8 498 cc overhead-valve single £62/0/0 (twin port), £59/10/0 (single port);
MR8 Special Sports 498 cc overhead-valve single £72/0/0;
M9 Deluxe Touring 498 cc side-valve £54/0/0;
M10 498 cc overhead-camshaft single £72/0/0;
M12 Lightweight 248 cc side-valve single £39/17/6.
Several of these were intended to pull one of the 12 AJS sidecars also on offer, including sports, touring and commercial models.

By 1927, it had become clear that push-rod overhead-valve designs were becoming dated in racing, so AJS introduced two new chain-driven overhead-camshaft racing models, the 349 cc K7 and the 498 cc K10. Jimmy Simpson rode a 350 to third place in the Junior TT and won races in Europe but in 1928 AJS used the overhead-valve engine in the TT. In 1929 there were again two machines with an overhead cam, this time the 349 cc M7 and the 498 cc M10. Wal L. Handley came second in the 1929 Junior TT for AJS. The following year Jimmie Guthrie

Stevens Motorcycles

The Stevens brothers tried again and started a new company as Stevens Brothers (Wolverhampton) Ltd to make 3-wheel delivery vans.

AJS Radios

 he convinced the rest of the AJS board that radio receivers had a big future. The first radios made by AJS Wireless and Scientific Instruments were launched in 1923, all high quality models aimed at the top end of the market. The most expensive cost £75, which was substantially more than many AJS motorcycles, although prices soon fell. Initial sales were good and by 1925, there were 10 models ranging from under £14 in a simple wooden case to over £50 with a finely veneered console cabinet. Radio production was increased and moved to a factory in Stewart Street. However, radio technology had advanced rapidly and AJS was forced to offer new designs in order to compete. The company’s reliance on battery power held them back at a time when rivals were turning to mains power and AJS was forced to adopt cheaper mass-production techniques. In 1928, the company decided to give up radio manufacture and sold the factory and remaining components to another manufacturer.

AJS Racing under AMC

Under AMC the AJS badge may have been put on the "bread and butter" Matchless motorcycles, but the Colliers were mindful of the AJS racing heritage, and used the name on some innovative racing machinery. These racing bikes kept the AJS name alive.

In 1935, at the Olympia Show, an air-cooled SOHC AJS 50° V4 was shown, a fully equipped road going version, which did not make it into production. In 1936 Harold Daniell rode a supercharged race version in the Isle of Man Senior TT, but despite its high top speed, it lacked acceleration.

In 1939, a water-cooled and supercharged version of the 495 cc AJS V4

 was built to compete against the supercharged BMWs then dominating racing. In 1939 the dry sump V4 was the first bike to lap the Ulster Grand Prix course at over 100 mi/h. It weighed 405 lb (184 kg). and its top speed was 135 mi/h. Then World War II intervened.

In 1951 AJS development engineer Ike Hatch developed a 75.5 mm bore x 78 mm stroke, three-valve-head version of the 7R making 36 bhp. It was called the AJS 7R3, and was Ike's response to the Italian multi-cylinder racers. They did well enough in their first year, not as well the second. For 1954 Jack Williams, the works team manager, developed the bike further, lowering the engine in the frame, and making some tuning changes that gave 40 bhp @ 7800 rpm. It immediately won the first two rounds of the World Championship and took first at the Isle of Man TT. These were factory specials, but one has survived, and a second has been reconstructed from spares.

AMC withdrew from the world of works and one-off road racing at the end of the 1954, with the death of Ike Hatch, and in the face of fierce competition from the other European bikes. After this AJS made a production version of the standard two-valve AJS 7R, for privateers. In 1954 Norton was also moved to the Plumstead works.

With the G15 line, AMC had built on the merits of the G12 but there were numerous changes to frame, forks, swinging arm, primary chaincase, transmission, cycle parts and lubrication system. The P11 was the last line of bikes with bonds to AMC. It used a modified G85CS frame but there were stronger forks, completely new cycle parts (making some was rather costly), altered lubrication and modified primary chaincases, to mention a few.

The G15 series was offered as 3 brands: Matchless G15 comprising G15Mk2, G15CS and G15CSR; AJS Model 33 comprising M33Mk2, M33CS and M33CSR; and last not least Norton N15CS (no Norton-branded roadster made as it would compete against the Atlas). The G15 series was produced from 1963 to 1969. They were initially for export only, but by 1965 these models were available in UK and Europe too.

Associated Motorcycles and the AJS name eventually ended up with Norton-Villiers

AJS two-strokes and Norton Villiers

AJS was acquired by the Norton Villiers Group. In 1967 Villiers decided that instead of supplying other manufacturers with their competition engines, they would build and launch their own complete motorcycles using the 250 Starmaker engine as a base. AJS would be the applied name. Villiers had plans to build a range of scramblers and an over the counter 250 road racer.
From 1962 Cotton motorcycles were the main customer for 250 Starmaker engines. The 250 Starmaker engines were used in the Cotton Cobra scrambler and the Telstar Racer. Cotton therefore was very involved in the development of the Starmaker engine. A strong link between the two factories existed, in part through Cotton engineer Fluff Brown.

Fluff Brown, being a keen and dedicated scrambler, worked mainly on the scrambles projects and supported the factory riders.

Peter Inchley, an acknowledged two-stroke expert, formerly from Ariel and BSA was involved with the 250 Road Race project. Peter rode a Bultaco-based 6-speed, 250 Villiers Starmaker-powered special to 3rd place in the 1966 Lightweight TT. Several pre production AJS 250 Racers were built and raced but the project came to halt in 1967 after an unsuccessful second TT attempt. The scrambles project continued with considerable success.

From 1966 to 1968, Villiers developed the "Stormer" Motocross motorcycle, with assistance from Peter Inchley, Fluff Brown, (and others). Development and supported scrambles riders included: Andy Roberton, Malcolm Davis, Dick Clayton, Chris Horsefield and Jimmy Aird. In 1968 Malcolm Davis won the British 250 Championship on a pre Stormer, Y4 scrambler.

In late 1967, a special project was undertaken with the Stormer. Four bikes were built at Marston Road, all equipped with spark arrestors on the end of the tailpipe and with a rudimentary lighting system. Three of them had 250 cc engines and were badged as AJS machines. The fourth one had the "360" engine (actually only 334 cc) and was badged as a Matchless. This bike was probably the last one built with a Matchless badge and the only 2-stroke Matchless. The four bikes were taken on by members of the Royal Air Force motor Sports Association and entered in the 1968 International Six-Days Trial.

The two-stroke AJSs had been built in Wolverhampton, at the Villiers factory but in 1970 the UK government provided a special subsidy that enabled AJS to open a new factory on Walworth Industrial Estate in Andover, where they assembled Stormer off-road motorcycles. The competition department was located next to the famous race track at Thruxton

.

AJS scramblers were produced from 1968 until 1974 in 250, 370 and 410 guises. The early 250 was designated the Y4. In 1969 The 370 (Y5) was added and the name changed to Stormer. The 410 followed in 1972. Famous British riders included Malcolm Davis, Andy Roberton, Vic Eastwood and Roger Harvey. Fluff Brown (formerly of Cotton (motorcycle)

A little known about motorcycle was the 37AT Trials bike which was partially built by Cotton Motorcycles using some AJS parts and Villiers's 37A engine. A pretty bike, of which probably 10 or so have survived.

By 1974, Norton Villiers were having financial trouble and Fluff Brown purchased the rights to manufacture the Stormer under the AJS banner and in September 1974 moved the business to Goodworth Clatford

. Initially selling spare parts for existing motorcycles, the business expanded to produce complete motorcycles still using the Starmaker based engines under the FB-AJS name.

The Starmaker/Stormer 4-speed engine was becoming outdated and could not compete with the new arrivals from manufacturers such as Husqvarna, CZ and later, scrambles bikes from Maico, Suzuki, Honda, Kawasaki and Yamaha. However, with support, the AJS remained a good option for the clubman or competitors who wished to ride a British two-stroke.

From 1974 Fluff Brown produced Stormer based scrambles and trail bikes from modified AJS stock. Keeping the model updated until 1980.
During the early 1980s Fluff Brown produced off road and trail bike AJ's with Austrian Rotax engines of 250 cc, 410 cc and 495 cc.

AJS Motorcycles Ltd. (today)

AJS Motorcycles Ltd. is now headed by Nick Brown (eldest son of Fluff Brown) and is a family run business. Since 2002 AJS have distributed a range of 124 cc to 300 cc Chinese produced road bikes in trail, roadster and custom cruiser styles. Their main market is Learner Legal 125's. Bikes.
