Triumph Quadrant - the inline four that never made it out the Coop @mrpetrol6634

mr petrol Built by Triumph engineering legend Doug Hele and the Experimental Department in 1973, the 1000cc inline four cylinder engine was to a potential successor to the 750cc 3 cylinder Triumph Trident. Only one was ever built and in testing it ran to 125 mph in a mild state of tune. The bike in this video is a replica bought by George Pooley using a T160 frame and two T160 engines. The work required to build this included cutting and modifying the crankcases and barrels, creating a crankshaft out of billet steel, a new engine cradle to house it and new carb inlets to feed it.

Little known fact - if you look closely you will notice the side panel have Quadrent not Quadrant. This is because original prototype was purposely spelt that way by the factory as an acknowledgement to it parent, the Trident.
