literally, custom-built means "hand made, customized or unique". This term initially meant customized motorcycles, very often based on a Harley-Davidson. The term has now finally lost this strict meaning and covers all motorcycles, whatever their engine size, providing a driving position with large handlebars and the feet out front. A custom bike is covered in chrome and often impresses the man in the street but the connoisseur is more difficult to convince. Among the most distinguished of this large family of strange machines, a special mention must go to the Kawasaki 600 Eliminator (with its state-of-the-art four cylinder engine) and to the Aprilia 125 Red Rose (with its stinking two-stoke engine which belches out smoke like Renault 21 Diesel).
