The Milton Keynes Knights are a Speedway team which originally operated under various names from 1978 until their closure in 1992. The team were based at the Groveway Greyhound Stadium until 1988. In 1989 they moved to the new stadium at Elfield Park. However following complaints of noise from a few local residents who phoned regularly to complain (even the day after a scheduled meeting was called off) and falling crowds the track closed in 1992. The site of the track (Elfield Park) is still unused. The site at Elfield Park had been used as a training track known as Bleak Hall.
