Born in Norwich in 1998,[1] the son of former Mildenhall Fen Tigers rider Paul Lambert, Robert Lambert rode motorbikes from the age of 3, and competed in grasstrack as a junior starting at the age of 6, going on to compete in junior speedway in 2008.[2] He gained much of his early racing experience in Germany between 2012 and 2013, where he was allowed to race at a high level at a younger age (14) than in the UK.[2] He rode in 2013 for King's Lynn Young Stars in the National League, scoring 15 points in his first meeting and winning five of his six races, and was promoted straight into main body of the StarsElite League team the following year, with the team's early fixtures arranged to ensure that he reached the age of 16 before the first meeting.[3][4][5][6] He impressed with a five ride paid maximum against Eastbourne Eagles in June.[7] He also rode in Denmark for Outrup and in Germany for Berghaupton in 2014.[2]
Starting with an assessed CMA of 3.00, by the end of the season this had risen to 5.32.[8] He was signed for a second year by the Stars for 2015, and was also signed by Peterborough Panthers for their 2015 Premier League campaign.[9]
In 2023, he was part of the British team that won the silver medal in the 2023 Speedway World Cup final. Lambert was the leading rider on the night but just failed to hold off Maciej Janowski in the last heat, which would have forced a run-off.[18] He returned to King's Lynn Stars for the latter part of the season following an injury crisis at the club. He finished the World Championship season with a sixth place finish[19] and ensured his place in the 2024 Speedway Grand Prix.[20]
Lambert starred again as he helped Great Britain secure the 2024 Speedway of Nations in Manchester, which was his second world team title[21], and then won his maiden Grand Prix in Vojens.[22]
