Castrol Six Hour (New Zealand)
The New Zealand Castrol Six Hour Race was an endurance motorcycle race that was held for fifteen years at Manfeild, Palmerston North from 1974 to 1988. Many of New Zealand's top international riders competed at the Six Hour race; winners included Dave Hiscock, Neil Chivas, Graeme Crosby, Aaron Slight, and Ginger Molloy. The race was characterised by its exclusive use of unmodified standard production motorcycles and a running start where the racers had to run to their machines before they could start. There was special provisions that the machines were no older than 3 years old, which was a boon to the motorcycle industry in New Zealand at the time which saw a dramatic rise in the sale of Motorcycles after these events.Winners
