Development
![H-Engine Four Stroke](https://upload.wikimedia.org/wikipedia/commons/a/ab/H-Engine_Four_Stroke.gif)
Designed as a team effort by Brough, 'Ike' Hatch, and Freddie Dixon, the engine has two horizontally opposed flat twins one above the other and geared together, thus rotating counter to each other forming an
H engine
An H engine is a piston engine comprising two separate flat engines (complete with separate crankshafts), most often geared to a common output shaft. The name "H engine" is due to the engine blocks resembling a letter "H" when viewed from the fr ...
. Connecting rods from opposed cylinders were of the fork and blade type and thus shared a common crank pin. All pistons moved in unison, that is to the left or to the right at the same time. The pistons could thus be counterweighted 100% yielding a perfect balance. Primary, secondary and higher-order sources of vibration canceled each other, as did the gyroscopic effects from each crankshaft.

described it a "flat vertical" engine. The four cylinders were equating to 988 cc, with the camshafts gear-driven. Further development work was done on the engine, reconfiguring it as (998cc),
with chain-driven camshafts.

The engine was a four stroke engine.
The frame was designed to accommodate the unusual engine and was welded together with a fully sprung plunger type springing for the rear wheel, unlike the cantilever swingarm suspension on the Brough Superior SS100

Surviving Golden Dreams
At least one Dream is running and is owned by John Wallis (the chairman of the Brough Superior Club, Nottingham, England). Two others are under restoration.
A Brough Superior Dream was on display at the British National Motorcycle Museum. Like many exhibits it was destroyed in a fire in 2003 but has since been largely restored, although it has never run, as there are no internals in the engine or gearbox.
