Kawasaki W1 – An Early British-Themed Japanese Motorcycle

Recently there have been a couple of comments on my website that mentioned the Kawasaki W1.  This was an early Kawasaki motorcycle, introduced in 1966, exported to the USA and other counties that was based on a design based on the British motorcycles of that era.

An Early Kawasaki W1

Kawasaki began to produce small engines that were used in other motorcycles in the early 1950s.  Eventually, by 1961, Kawasaki was making its own motorcycle and they subsequently joined up with Meguro Manufacturing, who was also making motorcycles, to make what eventually became the Kawasaki motorcycles line.  Kawasaki began to market motorcycles in the USA in 1964 following the successful lead of Honda.

In 1966 Kawasaki introduced the W1 with a vertical  2-cylinder 624cc engine.  This motorcycle had the largest engine in any Japanese motorcycle at that time.  The design of the motorcycle and the engine were based on existing BSA motorcycle designs.

The engine had a single Mikuni carburetor and was coupled to a 4-speed transmission.  The shifter is located on the right side of the motorcycle which was the style for British motorcycles of that time.  Nowadays all shifters are located on the left side of the motorcycle.

The Kawasaki W1 shown below is a later model which is distinguished from the earlier models as the later models had the gauges integral with the headlight bezel.

A somewhat updated model, the W2SS was introduced in 1968.  The W2SS was a little more sporty design, but still had the same 624cc engine, but with two carburetors.

The Kawasaki W2SS was also available with upswept exhaust in addition to the “pea-shooter” exhaust shown here.  This model was known as the W2TT.   As noted, the Kawasaki W2SS had two Mikuni carburetors.  The original Kawasaki W1 was dropped after 1968, but there was a followup model known as the W1SS.

The Kawasaki W1 and its derivatives were not particularly commercially successful.  The line was dropped after 1971.  Most people decided they would rather have a real BSA motorcycle as compared to a Japanese bike that looked like a BSA.  This was a time when the Japanese reputation for build quality was just being established and the British idiotic self-destruction of their motorcycle industry had not yet been fully discovered by the outside world.

I don’t recall seeing a Kawasaki W1 in person and I don’t think that there are many still running in the USA.  The images and information used in this post came from the following sources:
