Redrup is a historic brand of aircraft engines and motorcycles.
Redrup: Boyle & Redrup, Engineers, Leeds, later C. Redrup, Cardiff (1919-1922).
Redrup built three-cylinder airplane engines, but later also built them in a motorcycle, the Redrup Radial. The blocks were also delivered to Beaumont and British Radial.
Redrup also built a six-cylinder prototype. Under the name of Boyle and Redrup, motorcycles were probably not built. Boyle was a financier in the period when Redrup developed his first aircraft engine.
