About WSK M21W2B Kobuz 1977
1977 WSK M21W2B Kobuz: A Classic Touring Gem
The 1977 WSK M21W2B Kobuz stands as a testament to the golden age of motorcycle touring, capturing the essence of freedom and adventure in a compact, well-engineered package. As a product of WSK, a Polish manufacturer known for their versatility and innovation, the Kobuz was designed to cater to both urban commuters and long-distance riders alike. With its charming vintage aesthetics, the Kobuz exudes a character that appeals to both nostalgic riders and modern enthusiasts craving a slice of motorcycling history.
At the heart of the M21W2B is a spirited 174cc single-cylinder, two-stroke engine that delivers an impressive 14 horsepower at 6,000 RPM. This lively powerplant, paired with a 4-speed gearbox, provides a delightful riding experience, allowing the rider to navigate through city streets or open highways with ease. The 16 Nm of torque ensures that the bike has sufficient low-end grunt, making it responsive and enjoyable to ride, while the frugal fuel consumption of 3.00 litres per 100 km (approximately 78.41 mpg) means fewer stops at the gas station during those long tours. With air cooling keeping the engine at optimal temperatures, the Kobuz offers reliability and simplicity—a hallmark of the era.
The Kobuz’s chassis and suspension are equally commendable, featuring a robust steel frame that provides stability while maintaining a lightweight feel at just 112 kg (246.9 pounds). The front and rear drum brakes, while traditional, offer adequate stopping power, ensuring safety on the road. The suspension setup, with coil springs and oil shock absorbers, delivers a comfortable ride, absorbing the bumps of uneven terrain and enhancing overall handling. Additionally, the bike’s classic styling is complemented by a choice of vibrant color options, including orange, grey, and black, making it a standout on any road.
Pros:
- Fuel Efficiency: With a consumption rate of 3.00 litres per 100 km, the Kobuz is economical for long-distance touring.
- Lightweight and Agile: Weighing in at just 112 kg, the bike offers nimble handling and ease of maneuverability, perfect for city riding and country roads.
- Classic Aesthetic: Its vintage design and color options make the Kobuz a visually appealing choice for enthusiasts and collectors alike.
Cons:
- Limited Power: The 14 HP engine may feel underpowered for riders accustomed to modern motorcycles with higher performance capabilities.
- Basic Braking System: The drum brakes, while functional, lack the stopping power and responsiveness of modern disc brakes.
- Kick Start Only: The absence of an electric starter can be a drawback for those who prefer the convenience of modern starting systems, particularly in adverse weather conditions.
In summary, the 1977 WSK M21W2B Kobuz is a charming motorcycle that embodies the spirit of touring. With its reliable engine, classic design, and impressive fuel economy, it appeals to both seasoned riders looking for a nostalgic ride and new enthusiasts eager to discover the joys of vintage motorcycling.
