In an event which organisers said was now regarded as one of the top three of its kind in Britain, the Golden Era Run of vintage motorcycles set off and returned to the Yorkshire Air Museum at Elvington, near York.
Among the 58 two-wheeled vehicles taking part were 17 built between 1910 and 1917, including a 1914 Douglas 2 ridden by Christopher Habgood who travelled from Swindon to take part.
Entries came from across Yorkshire and further afield, including from Cumbria, Northumberland, Lincolnshire, Nottinghamshire, Lancashire and Cheshire.
After the ride-out which followed two routes - one 40 miles, the other 60 miles - the machines were displayed to the public in the museum grounds where their presence was complemented by two First World War bi-planes that had their engines fired up.
The event, being held for a ninth year, was organised by the North East section of the Vintage Motorcycle Club.
