1974 Norton MK2A 850 Commando Roadster: A Classic Icon of British Motorcycling
In the world of classic motorcycles, few names resonate as strongly as Norton, and the 1974 MK2A 850 Commando Roadster stands as a testament to the brand's commitment to performance and style.

Priced at a mere US$1900, this motorcycle is not just a piece of history; it’s a cherished investment for enthusiasts looking to capture the essence of 1970s motorcycling.
At the heart of the MK2A is an impressive 828cc twin-cylinder engine that produces a robust 60 horsepower at 6250 RPM.

The engine's compression ratio of 8.5:1 and a dual Amal carburettor fuel system ensure responsive throttle and a satisfying growl as you twist the grip. Whether you're navigating through city streets or carving up winding country roads, the Commando's Isolastic frame and twin-shock rear suspension provide a smooth ride, making it a joy to pilot.
The 1974 MK2A is not just about raw power; it's also a showcase of innovative features for its time. The motorcycle is equipped with a classic double cradle frame, designed to minimize vibrations while enhancing stability. The front suspension utilizes telescopic forks, complemented by a single disc brake for reliable stopping power, while the rear features a traditional drum brake system. With a seat height of 31 inches and a ground clearance of 6 inches, the Commando is accessible to a wide range of riders, making it both practical and stylish. Riders will appreciate its nostalgic kick starter, a nod to the purity of the riding experience, and the fact that it's one of the last Commandos with this feature—an essential point of pride for purists.
