Video: Speeding motorcyclist caught doing 156mph in Cambridgeshire Police have released footage of a motorcyclist dangerously weaving between vehicles on the busy A1 motorway on his Suzuki motorbike. The biker was filmed from a pursuing police motorbike dangerously undertaking and scraping through gaps during the eight-minute chase which reached speeds of 156mph. Peter Clarke, 44, failed to observe the police motorcycle following him on the north-bound triple carriageway from Alconbury, Cambs., before he was stopped near Sawtry. Sentencing him at Peterborough Crown Court Miss Recorder McAllister described his actions as "reckless driving threatening others." Clarke, from Broadgate, Sutton St Edmund, Lincs., admitted speeding but denied dangerous driving on a stretch of the A1 at Brampton at about 4.15pm on May 12. Speaking in his defence, Clarke said he was in total control of his motorcycle at all times and that it was built for speed. But he was convicted of dangerous driving by a majority verdict of 11 to one following a trial at Peterborough Crown Court. He was banned from driving for 18 months, fined £1,000 ordered to pay costs of £1,000 and a £15 victim surcharge.
