Overview
- On Tuesday, Dean Harrison posted a 133.925mph lap, the fastest ever opening-day effort on the 37.73-mile Mountain Course.
- Monday's opening session was cancelled after a red flag, so Tuesday provided the first full timed runs and an early pace benchmark.
- Harrison stayed top of the timesheets on Wednesday by lapping at 133.867mph on a Superstock Honda during a qualifying session that was short-lapped to allow an ambulance onto the course.
- Race control confirmed a sidecar crash at Brandish that sent Maria Costello to Noble's Hospital by helicopter and Shaun Parker by ambulance, with both reported conscious and injured.
- Multiple riders exceeded the 130mph mark across Superbike, Superstock and Supersport as teams swapped machinery to refine top-speed and stability ahead of race week starting May 30.
