I'm told that 
            prior to the RMCS / HDT collaboration on the KLR there was indeed 
            another such project given to producing a diesel motorcycle for the 
            Army.
           In 1990 Norton 
            Motors, Shenstone, were given the task of creating a water cooled 
            Classic and Krauser Commander for the NEC bike show. These (petrol) 
            bikes were completed but the show was a failure with heavy snow not 
            helping attendance.
        
        
          The team responsible for 
            these bikes was then due to start work on an Army version of the (petrol) 
            machine with a Diesel version to follow shortly there after. 
          These engines 
            were to be mounted in Endruo/off road style frames. Wolfgang Rauen 
            was given the task of getting a single rotor 294cc Norton Wankel Rotary 
            engine to run on Diesel and succeeded in doing this. 
          He spent many 
            hours on the dynamometer sorting out the fueling only for the company 
            to run out of money which lead to the whole Army project being canned. 
            
          The R&D people 
            were laid off and the company wound up Christmas 1990. 
          The original Norton 
            diesel project was for a portable marine fire pump. Compression was 
            too low to ignite the fuel oil so ignition plugs were fitted into 
            the spark plug holes.
           After the first 
            few seconds the engine was hot enough to combustion ignite and ran 
            like a diesel should. 
          Being that the 
            project was at a very early stage when it finished no photos or drawings 
            exist but David tells me the Diesel Wankel ran for many hours proving 
            its durability.
          Latest from the 
            2009 Hamm rally report:-
          Amongst other gossip, I also heard (with growing amazement 
            I must say) that someone had managed to unearth one of the original 
            Norton Rotary Diesel engines that are mentioned elsewhere on this 
            website. It was thought at one time they may be used to power a Military 
            motorcycle but most (petrol) versions ended up powering target practice 
            drones. Apparently this engine still runs, after a fashion, and the 
            owner is looking for a Norton motorcycle to put it in. Hopefully, 
            if it's done in time, this could be the main attraction at the anniversary 
            10th rally next year? I look forward to seeing this engine 'in the 
            flesh' as it were. Great stuff!
