As will her racing bike.
"Thrilled to have her here," Southworth said.
At this stage about 170 bikes will be on show, including four which are 100 years old as well as an 1898 steam-powered motorcycle.
"We will also have some great barn finds — old bikes that run but have never been restored."
Among them a 1926 Harley-Davidson and a couple of old 1920s Douglas motorcycles.
There will be road machines of all eras as well as racing machines and dragsters, and the two Indians (although one used a Ducati engine for the action sequences) from the film The World's Fastest Indian will be on show.
"We've got a great cross-section — something for the whole family to have a look at."
As well as the motorcycles the event will feature a swap meet and will also host the V12 Allison engine display as well as a great rolling steam engine — outside of course.
