Matchless built motorcycles in Plumstead, in southeast London, for most of the 20th century. Its range ran from narrow-angle V-twins and a V-4 tourer to a wartime dispatch single and a 497cc production racer. Each Matchless motorcycle below comes with only the numbers its sources actually support.

The name goes back to 1899. That year, Plumstead bicycle maker Henry Herbert Collier registered “Matchless” for his firm, H. Collier & Sons, according to the 2026 company history “The Pride of Plumstead”. Later, Matchless bought AJS in 1931, and the group became Associated Motor Cycles (AMC) in 1938.

1. Matchless Silver Arrow

The Silver Arrow was a refined touring machine built around a side-valve V-twin with its two cylinders set at a narrow angle. Matchless cast both cylinders in one block, which helped smooth the engine and cut vibration. Overall displacement was about 400cc.

However, sources differ on the debut. The Classic MotorCycle says Matchless unveiled it at the 1929 London Show. By contrast, the “Pride of Plumstead” history places it at the 1930 Olympia Show and lists 394cc. Either way, buyers hesitated. As The Classic MotorCycle puts it, the public “weren’t ready for such sophistication and sales were slow.”

2. Matchless Silver Hawk

The Silver Hawk followed a year after the Silver Arrow. Instead of two cylinders, it had four, arranged as a 593cc narrow-angle V-4 with an overhead camshaft. Both The Classic MotorCycle and the “Pride of Plumstead” history give that capacity.

According to the “Pride of Plumstead” history, a shaft drove the cam gear, and the engine used premium alloy castings. That made the Silver Hawk advanced and luxurious, but also costly to build. As a result, Matchless built roughly 500 before production ended in 1935, the same source says.

3. 1929–1940 Matchless Model X

The Model X was the big V-twin Matchless motorcycle of the 1930s, built from 1929 through 1940. It used a heavy-duty side-valve engine designed for reliability and torque rather than outright speed. That also made it a natural fit for sidecar work.

The engine found a home outside Plumstead, too. According to the “Pride of Plumstead” history, Brough Superior used a variant of the Model X motor in its SS80 from 1935 on. Meanwhile, The Classic MotorCycle lists “the sturdy Model X V-twin range” among the later Plumstead models.

4. Matchless G3L military motorcycle

During World War II, the G3L carried Matchless. It used a 348cc overhead-valve single, according to the “Pride of Plumstead” history, and the “L” stood for lightweight. The Classic MotorCycle lists the G3 engine at 347cc.

Its key feature, however, was up front. Matchless fitted its newly developed Teledraulic fork, a hydraulically damped telescopic fork, per The Classic MotorCycle. In fact, the “Pride of Plumstead” history calls it “the first significant British advance in front suspension in more than two decades.” Meanwhile, The Classic MotorCycle says Matchless offered prototypes to the military in late 1940, followed by “over 60,000 service models.”

5. Matchless G9

Then the G9 took Matchless into the postwar twin market with a 498cc parallel twin. The Classic MotorCycle dates it to 1948, while the “Pride of Plumstead” history says it debuted in 1949.

Also, the design had room to grow. According to The Classic MotorCycle, it later grew to 592cc as the G11, then 646cc as the G12 and finally 745cc as the G15. Still, the “Pride of Plumstead” history notes that neither the G11 nor the G12 matched the sales of BSA or Triumph twins.

6. Matchless G45

The G45 turned the G9 road twin into a production racer. Matchless launched it in 1952, and The Classic MotorCycle notes that the company had avoided factory racing support until then. According to the “Pride of Plumstead” history, the G45 put Matchless engines in AJS 7R frames.

At first, the twin did well. The Classic MotorCycle records a fourth place for Robin Sherry in the 1951 Senior Manx Grand Prix and a win for Derek Farrant a year later. After that, however, the G45 “failed to achieve the same success again,” as the same source puts it.

7. Matchless G50

The G50 was a single-cylinder racer with a 497cc overhead-cam engine. According to the “Pride of Plumstead” history, it made around 50 hp in race tune, with a top speed approaching 135 mph. The same source calls it lighter and more nimble than the Norton Manx, which made it a favorite of privateers and club racers.

Matchless built the engine by grafting a 90mm-bore barrel onto a 7R bottom end, says The Classic MotorCycle. AMC sold about 180 between 1958/9 and 1962, plus another 25 with lighting kits as the G50CSR for America, so they could race at Daytona. Even so, the best results came later. In 1964 Fred Stevens finished third in the Senior TT, and nine Matchless riders scored world championship points on G50s, the same source records.
