Leigh Scott Adams (born 28 April 1971 in Mildura, Victoria)[2] is an Australian former motorcycle speedway rider.

Adams won his first Victorian State Championship in 1989 in Mildura in what was only his third season of senior riding, beating Phil Crump at Olympic Park.

He made his Robins' debut when scoring 8+2 points from six rides against Oxford Cheetahs in a Gold Cup match at Blunsdon on 24 March.

[7] Adams won the first of his record ten Australian national titles in 1992, and also captured the World Under-21 Championship after beating Mark Loram in a race-off at Pfaffenhofen an der Ilm, Germany.

Adams remained at King's Lynn for the 2000 campaign and topped the Elite League riders averages, finishing the season on 10.24.

His paid maximum at Lakeside in August 2008 took him onto 5,482.5 points, surpassing the previous record set by Martin Ashby who scored 5,476.5 during his time with the Robins.

In 2011, Adams fulfilled a long-term ambition and entered the Finke Desert Race in Australia's Northern Territory near Alice Springs.

On 6 June, while on a training ride with his brother and other riders, Adams crashed his motorbike into rocky terrain and sustained multiple injuries including fractured vertebrae, extensive spinal cord damage and broken ribs.

He was flown from Alice Springs to Royal Adelaide Hospital where he underwent a six-hour operation to stabilise and strengthen his badly injured spine.

In 2014, Adams' son Declan finished 3rd in the Australian Under-16 Championship at the Pinjar Park Speedway in Perth, Western Australia.
