View source for Blackburne (motorcycles)

'''Blackburne''' was a trade name of '''Burney and Blackburne Limited''' a British manufacturer of [[motorcycles]] from 1913 to 1922 at Tongham near [[Farnham]], [[Surrey]]. They were also a major supplier of engines to other motor cycle and light car makers and continued to make these until 1937.

The company was founded by Cecil and Alec Burney who bought the rights to an engine designed by [[Geoffrey De Havilland]]. In 1923 the Burney brothers set up the Burney motorcycle company that lasted until 1925.

Around 1922, Blackburne first ran the [[Blackburne Tomtit|Tomtit]] two-cylinder light aircraft engine based on the [[Lympne Airport|Lympne]] 696&nbsp;cc [[V-twin engine|V-twin]].

In 1924 the company produced the [[Blackburne Thrush]] a three-cylinder light aircraft engine. The first engine design was of 1098&nbsp;cc, consistent with the capacity limit imposed for the 1924 light aeroplane trials at Lympne. The engine was enlarged and improved during 1925 to 1494&nbsp;cc for further air trials held during 1926. In late 1925 the engine passed the severe Air Ministry 100 hours operational test.<ref>{{citation |magazine=Flight magazine |date=31&nbsp;December 1925}}</ref> There are two known surviving engines, one of 1100&nbsp;cc and the other the 1500&nbsp;cc unit at the [[Shuttleworth Collection]] museum at Old Warden, although there may be others.
