The term café racer developed among British motorcycle enthusiasts of the early 1960s, specifically the Rocker (or ton-up boy) subculture. The term describes a style of motorcycle for quick rides from one “transport café”or coffee bar to another. Cafe Racers were also common in Italy, France and other European countries.

In 1973, US freelance writer Wallace Wyss, contributing to Popular Mechanics magazine, asserted the term café racer was originally used in Europe as a “put-down” toward riders who pretended to be road racers but instead only parked outside cafés.

The café racer is a light and lightly powered motorcycle that has been modified for speed and handling rather than comfort. The bodywork and control layout of a café racer typically mimicked the style of a contemporary Grand Prix roadracer, featuring an elongated fuel tank, often with dents to allow the rider’s knees to grip the tank, low slung racing handlebars, and a single-person, elongated, humped seat.

A signature trait was the use of low, narrow handlebars that allowed the rider to “tuck in” — a posture with reduced wind resistance and better control. These handlebars, known as “clip-ons” (two-piece bars that bolt directly to each fork tube), “clubmans” or “ace bars” (one piece bars that attach to the standard mounting location but drop down and forward). The ergonomics resulting from low bars and the rearward seat often required “rearsets”, or rear-set footrests and foot controls, again typical of racing motorcycles of the era. Distinctive half or full race-style fairings were sometimes mounted to the forks or frame.

The bikes had a utilitarian, stripped-down appearance, engines tuned for maximum speed and lean, light road handling. The well-known example was “The Triton”, a homemade combination of Norton Featherbed frame and Triumph Bonneville engine. It used a common and fast racing engine combined with a well-handling frame, the Featherbed frame by Norton Motorcycles. Those with less money could opt for a “Tribsa”—the Triumph engine in a BSA frame. Other combinations such as the “Norvin” (a Vincent V-Twin engine in a Featherbed frame) and racing frames by Rickman or Seeley were also adopted for road use.

Café racer styling evolved throughout the time of their popularity. By the mid-1970s, Japanese bikes had overtaken British bikes in the marketplace, and the look of real Grand Prix racing bikes had changed. The hand-made, frequently unpainted aluminium racing fuel tanks of the 1960s had evolved into square, narrow, fibreglass tanks. Increasingly, three-cylinder Kawasaki two-strokes, four-cylinder four-stroke Kawasaki Z1, and four-cylinder Hondas were the basis for café racer conversions. By 1977, a number of manufacturers had taken notice of the café racer boom and were producing factory café racers, most notably the Harley-Davidson XLCR.

In the mid-1970s, riders continued to modify standard production motorcycles into so-called “café racers” by simply equipping them with clubman bars and a small fairing around the headlight. A number of European manufacturers, including Benelli, BMW, Bultaco and Derbi produced factory “café” variants of their standard motorcycles in this manner, without any modifications made to make them faster or more powerful.
