The chase began after the teen's motorcycle was allegedly detected travelling at 81km/h in a 60km/h zone in Quakers Hill, in the city's north-west, about 7am (AEST) today. Highway patrol officers signalled for the teenager to pull over but he allegedly sped off – reaching speeds of between 160km/h and 170km/h. He was arrested by police after crashing the motorcycle at a roundabout. He was uninjured but was later charged with five offences, including driving in a dangerous manner and using an unregistered and uninsured vehicle.
