I recall seeing a bike going around the circuit on the back wheel,there was a rear outrigger fitted to stop the rider flipping the bike, i think his name was Dave Taylor.That year Honda brought out the CBR1000 it was an in line six cylinder and they loaned some to the marshals,and they were escorting him around the course.I can't remember the make of his bike.
Food for thought, Dave Taylor died of cancer,Mike Halewood died going for fish & chips,and last but not least Barry Sheene has died of cancer.When you think of the feats these riders have done and the speeds they were going.....
