Rebels with a cause: Bikers upset at "scruffy" description Furthermore, almost of half of British bikers (42 per cent) are totally free of tattoos, piercings, facial hair or gang markings. The actor George Clooney, the maths star Carol Vorderman and the model Melanie Sykes, all photographed on motorbikes, also contrast with the previous definition. OUP has now changed the Oxford Dictionaries Online definition of biker to: "A motorcyclist, especially one who is a member of a gang or group: a biker was involved in a collision with a car." Almost three quarters, 74 per cent, believe the old definition was inaccurate, with 21 per cent saying they are "outraged and offended" by it. And 65 per cent of motorcyclists spend the majority of their time riding alone - and not as a "member of a gang," a study by insurance firm Bennetts found. Over half, 60 per cent, believe the old definition is "dated and irrelevant," and just 2 per cent say it was "correct and accurate," the poll of 524 bikers found. Bennetts data shows today's biker is most likely to be aged over 35, middle class, working in IT or telecoms and likely to ride a Honda. Whether commuting or riding as a hobby, the image of a "biker" has changed from that of a Hells Angel. When the term "biker" was used in the 60s and 70s, it described gangs of long haired, leather clad trouble makers. They generally drove at dangerously high speeds, often to confront rival gangs elsewhere. The bikers were described in the media in early 60s as "ton-up" boys. Hannah Squirrell, from Bennetts, said: "In the early 60s, 'biker' was a relatively new term which provoked fear among many, partly due to their image portrayed in the media. Fortunately, since then, bikers have grown away from the cliched stereotype and now encompass all sectors of society. That is evident by the recent popularity growth of adventure-bikes and scooter sales. It's clear from the research that the image of a biker in 2013 is not the same as 50 years ago. We are pleased the Oxford Dictionary definition has finally been updated. However, it's worth pointing out that not every person who rides a motorcycle describes themselves as a 'biker' and we're not all members of gangs - so there is still some way to go. Oxford University Press spokeswoman Nicola Burton said the change to the definition was made on February 22. She said: "This change has been made to reflect a minor shift in contemporary use of the word 'biker'. Our research suggests 'biker' is now more closely aligned with 'motorcyclist' than words such as 'hell's angel'. We also updated the usage example, which is intended to provide an illustration of how the word could be used in a sentence. Oxford Dictionaries definitions are based on evidence of language usage. They are not meant to prescribe how language should be used, but instead describe language as it is used by the majority of its speakers, based on our objective research.
