it is a Triumph but it is using the Rocket 3 motor. The Triumph motors were straight up and the Rocket 3 motors had the forward cant. Must be about a 74 or 75. Love the use of the original tank.

 

It is a 1975 Triumph Quadrant four, 1000cc. A factory prototype. http://www.venturerider.org/forum/showthread.php?t=83997&page=13

 

Try to keep up, Paul.

Just kidding. It was solved yesterday morning.

By Golly! You are correct!

Originally for export only when launched in 1963, the Electra was Norton’s first motorcycle to offer electric starting and carry flashing indicators as original equipment. A revvy overhead valve short-stroke twin developed from the earlier 250cc Jubilee and 350cc Navigator, the 383cc Electra has a Lucas starter motor sited behind the cylinders and driving the crankshaft by chain. Despite its modernity, the Electra was not a success: its shortcomings included unreliable starting, engine vibration and heavy fuel consumption. Norton, whose entire production was moved to Associated Motor Cycle’s London plant in 1963, dropped the model after two years.
