The Norton Motorcycle.

In the early Arthur Alexander Sidney a revolutionary high speed engine of 500cc capacity was comprised mainly or Aluminium. to help prove the engine, to simulate different loads it and thirdly to show it to potential he fitted it into a Norton frame.

His son, Arthur Anthony joined him in 1956 at the workshop in Brighton, and together they the Diesel Motorcycle driving it as far a as West Drayton, London another engine had been to a Dumper Truck owned by a called Road Machines.

The produced 10-14 BHP at around RPM. It was possible to kick-start the with the valves lifted but on mornings it really needed to be or towed behind a car.

The Engine.

The engine itself was from Aluminium to a: help the heat and b: save weight. Any of strength, considering the high ratio, was compensated for by the use of tensile rods which ran from the bearings up to the cylinder head. The also carried a relief for the

The combustion chamber was of the ‘squirt being machined into the iron cylinder head. injection was by CAV pump with nozzle (to give optimum profile and combustion).

The crankshaft was lubricated and ran in phosphor bronze bearings (a massive construction) and the block was lined.

Testing place on a Heenan Fronda break Dynamometer. Only 4 were made and all parts manufactured locally in the Brighton At one time Ford was interested in the patent but this was not followed up.

This next machine was by A Freeman Sanders of Newlyn, at some time during the mid of the last century. The engine 18.5hp at 4500rpm and was reportedly of speeds up to 70 mph. Fuel was said to be in the region of 140mpg.

The below were from the 1992 edition of The Classic

This 490cc machine was in the Practical Motorist and Motor magazine November 1954 and in The cycle’s September edition of the year.

A great this!


I’m told prior to the RMCS / HDT collaboration on the KLR was indeed another such given to producing a diesel for the Army. IN 1990 Norton Shenstone, were given the of creating a water cooled and Krauser Commander for the NEC bike These (petrol) bikes completed but the show was a failure heavy snow not helping

The team responsible for these was then due to start work on an version of the (petrol) machine a Diesel version to follow there after. These were to be mounted in Endruo/off style frames. Wolfgang was given the task of getting a rotor 294cc Norton Rotary engine to run on Diesel and in doing this.

He spent many hours on the sorting out the fueling only for the to run out of money which lead to the Army project being

The RD people were laid off and the wound up Christmas 1990. The Norton diesel project was for a marine fire pump. was too low to ignite the fuel oil so ignition were fitted into the plug holes.

After the few seconds the engine was hot enough to ignite and ran like a diesel Being that the project was at a early stage when it no photos or drawings exist but tells me the Diesel Wankel ran for hours proving its durability.
