John McGuinness (born John Warren McGuinness, 16 April 1972) is an English professional motorcycle racer who until early 2017 had a long association with Honda machines having factory support in road races like the Isle of Man TT, the North West 200, the Macau Grand Prix, and on the short tracks in the British Superstock and Supersport series.
In May 2017 McGuinness suffered serious injuries during practice for a race in Northern Ireland, ending his race participation for the remainder of the season. The accident occurred shortly after the release of his book.
In January 2018 he announced his intended-return as a TT rider with Norton Motorcycles as team-mate to Josh Brookes, but his recovery was not complete and in April announced via social media that he had suffered a setback that prevented any competitive riding. He was able to complete a Parade lap of the TT circuit on a Norton SG4 during the June 2018 event, but returned in August to win the 2018 Classic TT on the 500 cc Paton.
McGuinness is a specialist Isle of Man TT solo motorcycle rider with 24 wins. In 2013, a left-hand bend on the Snaefell Mountain Course used for TT races before the top of Barregarrow on the main A3 road was named McGuinness’s in recognition of his wins, together with Dave Molyneux who was similarly honoured.
He was part of a multi-rider motorcycle endurance-racing team called Honda TT Legends. In April 2016, the RAC announced McGuinness as recipient of the Segrave Trophy for 2015.
