[4] Kennett began his speedway career during the 1970 British League Division Two season, after he joined the Eastbourne Eagles.

He soon established himself as a heat leader and the following season in 1971, was instrumental in helping Eastbourne win the league title.

[8] He stayed with Oxford for the next three seasons, scoring solidly but the team underperformed until 1975, when they won the Midland Cup in a dramatic competition that saw home and away draws with Swindon Robins, requiring reruns and a home and away victory over Wolverhampton Wolves to secure the trophy.

[4] The next couple of seasons, he rode for King's Lynn Stars and Wimbledon Dons before returning to Eastbourne again in 1985.

[citation needed] He was later a team manager for the Oxford Cheetahs, during the years that they had no home.
