Organisers say as many as 1,500 bikes could be out and about tonight in memory of 26-time TT winner Joey Dunlop.
The annual parade lap around the Mountain course gets underway at 7pm this evening (27 August) and raises money for the Joey Dunlop Foundation charity.
The lap takes place on open roads, led by police cars.
The event is usually held during TT week but was moved this year as the Festival of Motorcycling is themed around 'yer maun'.
Kevin Quirk, the charity’s secretary, says everybody is more than welcome to take part:
