I'd have to guess that most South African men love motorbikes, even if they don't own one themselves. When visiting Cape Town you're bound to come across many, from new to old, Harley to Honda.
"Think Bike" is a campaign run by motorbike enthusiasts in an effort to remind drivers of the presence and vulnerability of bikers on the road. Having lost a friend to the negligence of a truck driver, I'm always cautious when there's a bike around.
While I'm a superbike fan myself, as a motorist I love Harleys... they're easy to hear approaching and hardly ever whizz past in a superbike-like blur of colour and sound.
