In normally aspirated form, Radial Motion engines can produce 100hp per litre. Supercharged variants are available with higher power levels.


Expressing the visual appeal of traditional radial motors from times gone by, the Radial Motion product is clean and uncluttered with symmetry that enhances any custom build.



In keeping with the philosophy of "the affordable dream", all Radial Motion products are self-serviceable and simple in operation. Rebuilds are straightforward and engines have long service intervals due to their robust nature.


Fresh off the dyno, our compact radial engine takes a trip in a trike and meets up with a distant cousin in the form of a Boeing biplane.
