BSA M 21

Introducing the 1955 BSA M 21, a remarkable all-rounder that epitomizes the golden age of British motorcycling. With its rugged yet elegant design, the M 21 was aimed at the adventurous spirit of the 1950s, appealing to both casual riders and enthusiasts seeking a reliable companion for their journeys. As one of BSA’s flagship models during this era, it showcased the brand’s commitment to quality and performance, making it a noteworthy entry in the market for both commuting and leisure riding. At the heart of the M 21 lies a robust 591 cc single-cylinder, four-stroke engine that delivers a modest yet dependable 15 horsepower at 4,000 RPM. This power is accessible and smooth, allowing riders to navigate a variety of terrains with confidence. The bore and stroke dimensions of 82.0 x 112.0 mm strike a balance between torque and rev range, ensuring that the bike performs well at lower speeds while still being capable of spirited rides on open roads. The carburettor fuel system and magneto ignition contribute to its user-friendly nature, and with a wet multiplate clutch paired with a chain final drive, the M 21 offers a seamless and engaging riding experience, combining the charm of classic engineering with the functionality demanded by riders of its time. The BSA M 21 is equipped with features that enhance both comfort and control. Its single cradle frame provides a solid foundation, while the hydraulic telescopic front suspension and twin shock rear suspension work together to absorb bumps and provide a smooth ride. The drum brakes, while traditional, offer reliable stopping power, ensuring that riders can confidently navigate both city streets and rural paths. With a fuel capacity of 11.36 liters, this motorcycle is built for longer journeys, allowing riders to enjoy the open road without frequent stops. The classic kick-starter serves as a nostalgic nod to the era, reminding riders of the simplicity and satisfaction of starting their adventure with a gentle kick. **
