There have been some good videos made in the past too, i remember watching them on tv as as kid. Th one that really sticks in my mind even today, was Steven Berkoff the actor telling you the "Think Bike", he then caved in a melon with a bat to illustrate the impact to a bikers head in a crash!!!
Still stuck in my head after 30 yrs or so. Might have a look for it later and post it up if i find it.
