The 500 New Imperial Twin is a classic British motorcycle that was produced by the New Imperial Motors Ltd. company. New Imperial was a renowned motorcycle manufacturer based in Birmingham, England, known for producing high-quality bikes with innovative engineering and performance.
The 500 New Imperial Twin, also known as the Model 23, was introduced in the early 1930s. It was powered by a 499cc air-cooled, side-valve twin-cylinder engine, which was considered advanced for its time. The engine design allowed for smooth power delivery and a respectable top speed, making it suitable for both touring and everyday commuting.
One of the standout features of the 500 New Imperial Twin was its lightweight construction. The motorcycle’s frame and components were designed to minimize weight while maintaining durability, which contributed to its agile handling and responsive performance.

New Imperial was also known for incorporating innovative technologies into their motorcycles. The 500 New Imperial Twin featured a patented “Silentbloc” system, which reduced vibration and improved overall comfort for the rider. This feature was ahead of its time and added to the appeal of the motorcycle.
During the 1930s, New Imperial achieved racing success with their 500cc motorcycles, further enhancing the brand’s reputation for performance and reliability. The success on the racetrack translated into increased popularity among enthusiasts and riders looking for a dependable and capable motorcycle.
However, like many other motorcycle manufacturers, New Imperial faced challenges during the Great Depression, which impacted their production and sales. As a result, the company struggled financially in the late 1930s.

Ultimately, New Imperial ceased motorcycle production in the early 1940s, during World War II, and the company was later dissolved. Despite its relatively short existence, New Imperial left a lasting impact on the motorcycle industry, and its bikes, including the 500 New Imperial Twin, are now sought after by collectors and vintage motorcycle enthusiasts.
Today, the 500 New Imperial Twin is a cherished classic motorcycle that represents an important chapter in British motorcycling history. Its innovative design, racing success, and reputation for performance continue to be celebrated by motorcycle enthusiasts, ensuring its place as an enduring icon of the vintage motorcycle era.
