BMW “Airheads” are mainly those motorcycles which feature the BMW 247 engine — an air-cooled, two-valve, flat-twin boxer engine produced from 1969 to 1995. The “/5” (Slash 5) series were introduced in 1969, “/6” (Slash 6) series in 1974, and “/7” (Slash 7) series in 1977.
The Airheads were never seen as the lightest, fastest, or nimblest motorcycles on the market, but they earned a reputation as soundly engineered, immanently roadworthy machines. In the last few decades, they’ve become a favorite of customizers, who convert their Airheads into cafe racers.
Typically, such a conversion involves stripping the bike of any factory fairings, installing clip-on handlebars, fabricating a performance exhaust, possible suspension and brake upgrades, a solo seat or tail section, and more. Many builders cut off the old subframe and fabricate a new one, and engine performance upgrades are common as well.
Below is a selection of the many Airhead cafe racers we’ve featured.
