The 1946 Cotswold Cup was the last trial in which the motorcycle took part
A historic motorcycle is to return to Gloucestershire where it can be "seen and appreciated" close to where it was made.
The Baughan motorbike and sidecar, which was built in Stroud in 1929, is being presented to the Museum in the Park on Tuesday, 20th July, 2010.
The long-term loan is being made by the British Motorcycle Charitable Trust who will also make a donation to the museum to pay for display materials.
"We are very grateful to the Motorcycle Trust for giving us the opportunity to display this fascinating piece of local engineering and sporting history," said David Mullin, museum collections officer.
"I have no doubt it will be a big hit with museum visitors."
The motorcycle won many trials between 1929 and 1946 and was so successful that in 1935 the company boasted that 'It is being barred from a number of important events on the ground that it is not possible for other machines to win.'
The secret of its success was that the engine drove the sidecar wheel, as well as the rear wheel.
This unusual design gave it exceptional grip on mud and grass.
The motorcycle has been restored by Graham Stagg, whose father became Baughan Motors first apprentice in 1924.
He went on to have a long career with the company and also won many trials and scrambles riding Baughan motorcycles.
John Kidson, a Trustee, said: "The British Motorcycle Charitable Trust exists to preserve and promote public understanding and enjoyment of our motorcycling heritage.
"We are pleased that this machine can now be seen and appreciated close to where it was made and had such great sporting success."
