The AJS Heavyweight 350, produced from 1957 to 1966, was a motorcycle renowned for its versatility, reliability, and impressive performance. This iconic British machine, powered by a robust 350cc single-cylinder engine, was widely used for both civilian and military purposes.

**Engine and Transmission**

At the heart of the AJS Heavyweight 350 lay a 349cc air-cooled, single-cylinder engine that delivered dependable power and torque. The engine featured a bore and stroke of 70mm x 87mm, resulting in a compression ratio of 6.8:1. A single Amal Monobloc carburetor handled fuel delivery, ensuring smooth and responsive engine response. The engine's power was transmitted to the rear wheel via a robust 4-speed gearbox with a foot-operated shifter.

**Chassis and Suspension**

The AJS Heavyweight 350 was built upon a sturdy tubular steel frame that provided a solid foundation for its components. The front suspension employed leading-link forks with coil springs, offering a smooth ride and precise handling. At the rear, a rigid frame with twin Girling shock absorbers ensured stability and control over rough terrain.

**Brakes and Wheels**

Stopping power for the AJS Heavyweight 350 was provided by 8-inch single-leading-shoe drum brakes on both the front and rear wheels. These brakes, actuated by cable-operated levers, delivered ample stopping force even in demanding conditions. The motorcycle rolled on 19-inch spoked wheels fitted with tires that provided a balance of grip and durability.

**Styling and Features**

The AJS Heavyweight 350 exuded a classic and utilitarian aesthetic. Its metal fuel tank, painted in a distinctive shade of dark green, featured a prominent AJS logo and rubber knee pads for comfort. The motorcycle's handlebars were wide and swept back, providing an upright riding position. A simple instrument cluster, mounted on the fuel tank, displayed essential information such as speed, mileage, and fuel level.

**Performance and Handling**

The AJS Heavyweight 350 was capable of achieving a top speed of approximately 80 mph, making it a versatile machine for both city commuting and weekend excursions. The motorcycle's handling was considered neutral and well-balanced, with precise steering and stable cornering. Its robust construction and reliable mechanicals ensured that the AJS Heavyweight 350 could endure the rigors of daily use and long-distance travel.

**Legacy**

Throughout its production run, the AJS Heavyweight 350 gained a reputation for being a rugged, reliable, and practical motorcycle. It was a popular choice for both civilian riders and military personnel, who appreciated its versatility and ease of maintenance. Today, the AJS Heavyweight 350 remains a sought-after classic among collectors and enthusiasts, prized for its historical significance and timeless appeal.
