Adam Lyon has died after crashing during the opening Supersport race at the Isle of Man TT.

The 26-year-old Scot crashed his Yamaha just past the 28-mile mark on the penultimate of four laps.

Organisers confirmed later in the day that Lyon, making his Isle of Man TT debut this year, had died in the incident.

“ACU Events Ltd regrets to confirm that Adam Lyon, 26, from Helensburgh in Scotland was killed in an incident during the Supersport 1 Race today at the Isle of Man TT Races,” began a statement.

“The accident occurred at Casey’s, just after the 28th mile of the course, on the 3rd lap of the race.

“Adam was a newcomer to the TT this year. He qualified in 24th place for today’s race with a fastest lap of 122.261 which he improved to 122.636mph on the opening lap of today’s race. His fastest lap of the TT course – 123.443 – was in Friday’s Superbike qualifying session.

“Adam lapped at 122.499 as a newcomer at the Ulster Grand Prix in 2017, finishing 11th in the second Supersport race. He finished sixth in the 2010 Pirelli National Superstock 600 Championship with podiums at Croft and Silverstone.

“ACU Events Ltd wishes to pass on their deepest sympathy to Adam’s family and friends.”

The tragedy comes five days after Dan Kneen lost his life in a crash during Superbike qualifying.

Michael Dunlop (Honda) broke his own Supersport lap record on the way to victory in the race after an initial battle with Dean Harrison (Kawasaki).

Peter Hickman took out the RL360 Superstock race which came later in the day.

Monster Energy Supersport TT Race 2 takes place on Wednesday morning (local time), when the program resumes.
