Kawasaki W 1 SS
1966
1966
The Kawasaki W1 SS, released in 1966, marked a significant step for the Japanese manufacturer in the large-displacement motorcycle market. Building upon the earlier W1 model, the W1 SS aimed to offer improved performance and styling. This bike directly competed with established British parallel twins of the era, such as the Triumph Bonneville T120 and BSA Lightning. The W1 SS represented Kawasaki's ambition to challenge these dominant players and establish itself as a serious contender.
At the heart of the W1 SS lies its 624.0 ccm (38.08 cubic inches) twin-cylinder, four-stroke engine. This powerplant allowed the motorcycle to achieve a top speed of 180.0 km/h (111.8 mph), a respectable figure for the mid-1960s. The fuel tank capacity is 15.00 litres (3.96 US gallons), offering a reasonable range for touring or longer rides. The engine's design focused on reliability and usable power, characteristics that Kawasaki emphasized in their marketing.
The riding experience on the W1 SS is characteristic of 1960s motorcycles. The upright stance provides good visibility, making it suitable for navigating urban environments. While not a dedicated touring machine, the 15-liter fuel tank allows for decent mileage between stops. The suspension, typical of the era, is adequate for smooth roads, but riders should expect a somewhat firm ride on rougher surfaces. The motorcycle offers a classic riding experience, connecting the rider to the road in a way that modern bikes often filter out.
The Kawasaki W1 SS appealed to riders seeking a stylish and capable motorcycle with a classic aesthetic. It was targeted toward those who appreciated the look and feel of British bikes but desired Japanese reliability. The W1 SS offered a compelling alternative and helped pave the way for Kawasaki's future success in the global motorcycle market. While not the fastest or most technologically advanced bike of its time, the W1 SS successfully combined performance with a timeless design, making it a desirable machine for enthusiasts of vintage motorcycles.
✅ Why buy this bike?
• Classic styling evokes a strong sense of nostalgia, appealing to vintage motorcycle enthusiasts seeking authentic retro design. • Relatively simple air-cooled parallel-twin engine is easy to maintain and repair, reducing long-term ownership costs and complexity. • Decent torque output from the 624cc engine provides adequate power for comfortable city riding and enjoyable backroad cruising. • The W1SS offers a relatively comfortable riding position for a vintage motorcycle, suitable for shorter to medium-length journeys. • Its historical significance as one of Kawasaki's early large-displacement models makes it a collectible and appreciating asset. • Compared to modern bikes, it offers a raw and engaging riding experience, connecting the rider directly to the machine.⚠️ Things to consider
• Drum brakes offer limited stopping power compared to modern disc brakes, requiring increased stopping distances and rider awareness. • The suspension is basic and provides a less refined ride compared to modern motorcycles, particularly on rough road surfaces. • Finding replacement parts can be challenging and expensive due to its age and limited production numbers, impacting maintenance. • The lack of modern electronics and safety features requires a higher level of rider skill and experience for safe operation. • Fuel economy is poorer than modern motorcycles due to the carburetor and older engine technology, increasing running costs.Rule of thumb: under 125cc / 15HP → A1, under 47HP → A2, above → A.
