What You’re Watching
The Isle of Man TT is the most dangerous motorcycle race on the planet. 37.73 miles of real public roads through towns, villages, and countryside on the Isle of Man off the northwest coast of England. No run-off. No gravel traps. Stone walls, hedges, lampposts, and houses lining a course that hasn’t changed in over a century. The riders who compete here are a different breed entirely.
In this clip from the 2025 TT Superstock race, Dean Harrison — one of the fastest riders to ever lap the Mountain Course — comes flying through at 197 MPH and passes TT legend John McGuinness like he’s standing still. McGuinness has 23 TT wins. Harrison just went past him at nearly 200 miles per hour on a public road. That’s the TT.
