Ben Birchall (born 21 January 1977)[1] and Tom Birchall, (born 23 December 1986),[1] from Mansfield, Nottinghamshire, are English motorcycle-with-sidecar road race World Championship-winning competitors in both the F1 (2009 and 2018 seasons) and F2 categories (2016, officially known as F2 Sidecar World Trophy, using 600 cc engines running concurrently with 1000-engined outfits) and again in the 2017 season – when all competitors used 600 engines.

[12] The short (F2) chassis needed to comply with Isle of Man TT regulations was not ready in time to test thoroughly before the May/June event, meaning the brothers cancelled their race plans due to unproven safety and performance reasons.

[12] Ben Birchall suffered back injuries in a practice crash at the Croatia world championship round, needing skin grafts.

[14] In 2012 the Birchalls joined with former World Champion sidecar racer and TT winner Klaus Klaffenböck and former passenger Adolf Hanni in a new team called Cofain Racing by Klaffi, using long (F1) and short (F2) LCR chassis with Honda engines prepared by Chris Mehew.

The machine was extensively damaged needing a new chassis and bodywork, but after the team's rebuild they resumed practising and in the actual races gained second and third places in the two-leg event.

Back on the Isle of Man, in their absence, their Spirit of TT Award was received on their behalf by father John Birchall and Klaus Klaffenbock.

[17] They entered their first Southern 100 short-length road races in July 2012 and were the first newcomers to debut as winners of the sidecar championship,[18] also receiving their Spirit of TT award on their return to the island.

[25] With their two 2017 Isle of Man TT race wins, this was the first time in history of the sport that both prestigious titles were won by the same team in a single year.
