Driving rain, gusting winds and a treacherous track surface combined to make the 1985 British GP one of the most gruelling for many a year. Freddie Spencer demonstrated his complete mastery of all conditions by streaking away on the Rothmans Honda. Marvel at the skill needed by the Louisiana rider as he copes with slides, spray and flying trackside garbage as he slips and slithers round the ice-like Northamptonshire track. The camera crews covered every corner at Silverstone and sensational views from the on-bike camera carried by Ron Haslam, provide the ultimate filmed record.
