"Moment of madness" rider drove at 122mph A MOTORCYCLIST caught by police travelling at 122 mph in a 40 mph zone was yesterday banned from driving after a sheriff threw out his argument that going at more than three times the speed limit in a built up area was "not dangerous." Robert Lockhart was recorded at the speed on his Suzuki Hayabus motorbike on the outskirts of Dundee last May. He was seen by officers overtaking cars as he left a roundabout between two housing estates. They watched as the married father-of-one accelerated "rapid and hard" past them - reaching 122 mph on the dual carriageway. Dundee Sheriff Court heard the road was flanked by a pedestrian footpath "inches from the road," a pub, nursing home, nursery, hotel, shops and housing schemes on either side. Lockhart told police it was a "moment of madness" after he was pulled over. His lawyers told the court that he should be found not guilty of dangerous driving because his speed was "not obviously dangerous." However, Sheriff Elizabeth Munro told the offshore worker: "I can't think anybody in the world would think driving at 122 mph in a 40 mph limit was what a careful and competent driver would do." PC Patrick Nicol, 36, of Tayside Police's Road Policing Unit, said that Lockhart was driving a bike which was "one of the most powerful bikes in production when it came out." Lockhart, 51, of Brandywell Road, Abernethy, Perthshire, had denied that on 26 May he drove his bike dangerously on the A92 Dundee-to-Arbroath road. Sheriff Munro said she had "no hesitation" in finding him guilty. He was fined £500 and banned for 18 months.
