Antique and vintage motorcycles take center stage at the Owls Head Transportation Museum’s annual Vintage Motorcycle Festival and Antique Aeroplane Show Saturday, Sept. 3, and Sunday, Sept. 4, from 9 a.m. to 3 p.m. Owners of pre-1996 motorcycles are encouraged to exhibit and will be admitted free of charge. For the fourth year running, a special designated parking area for modern motorcycles will also be set up in the main parking area. With more than 400 exhibitors in 2015, the Vintage Motorcycle Festival attracts antique, custom and racing bikes from all over New England.

While the theme of this popular show is motorcycles, guests arriving in their pre-1996 vehicles, as well as organized clubs, receive free admission to this show and all other museum (non-auction) events. Clubs are encouraged to call ahead to arrange parking. Exhibitor gates open at 8 a.m.

In addition to assorted vintage motorcycles of all kinds, an array of family activities will include demonstrations, free Model T rides and (weather permitting) antique aeroplane demonstrations. Young children are encouraged to practice their driving skills in the Kids Corral area, which features pedal cars and pedal planes.

The museum will showcase its collection of early motorcycles, which includes an 1868 Roper Steam Velocipede, 1901 Steffey Motorbike, 1922 Royal Enfield, 1930 Henderson Streamline Motorcycle, 1931 Indian Four, 1932 Harley Davidson V Motorcycle, 1938 Indian Scout and 1946 Whizzer Motorbike. Its newest acquisition, a 1919 ABC Sopwith Motorcycle, will also be on display. A selection of automobiles from the ground vehicle collection will be driven and demonstrated throughout the weekend and visitors may get a ride in a special auto from the museum’s collection.

Antique aeroplane demonstrations will take place weather permitting; planes included in demonstration may include a 1917 SPAD, a 1923 Fokker C.IVa, a 1941 Boeing Stearman and a 1930 Travel Air Speedwing. Open flightline is scheduled on each afternoon during the show and provides an opportunity for visitors to see, hear and experience the planes close up and to visit with the pilots.

Weather permitting, rides in the museum’s 1941 Stearman biplane and 2011 Waco YMF-5 biplane, will be available for purchase throughout the event weekend. Stearman rides are $250 and can accommodate a single passenger. Waco rides are $350 and can accommodate two passengers (some weight restrictions apply).

Event admission is $18 for adults. Children under 18, as well as retired and active duty military, are admitted free every day. For more information about the event, call the museum at 594-4418 or visit its website at owlshead.org.
