The Norton Nemesis was a concept from Norton before it went bankrupt which was powered by a 1500cc fuel-injected V8 producing 235-280hp. The engine was only 16 inches wide and based on F1 technology. The 280hp version would improve substantially upon the design of the 235hp Nemesis and would incorporate 3 spark plugs per cylinder, giving the motorcycle greater fuel efficiency and power, and have push button shifting and an active suspension.

The framework of the Nemesis was manufactured from an aluminium alloy and the body work utilized extensive carbon-fibre composite materials for maximum chassis strength with a relatively light weight, and featured a custom designed proprietary suspension system. Other specially designed features of the Nemesis include customized Champion spark plugs and ignition coils, two camshafts per cylinder bank, a 6-speed gearbox and 4 valves per cylinder.

The Nemesis was going to be Norton's, and indeed the world's fastest, most powerful motorcycle. Driven by its own 1500cc fuel injected V-8 engine producing 235-280hp, the Nemesis was expected to reach top speeds in excess of 200 mph. With only a few exceptions, all Nemesis parts have been specially designed and manufactured for this one model, resulting in the highest specification standards of any production motorcycle made today. Norton had its eye on the future of the Nemesis as well as the present. In coming years the Nemesis would have been available with push button shifting, a rear view video monitor to replace side mirrors and a unique active suspension system linking the engine computer and suspension so that the engine and chassis work as one to maximize power during acceleration and control in high speed cornering.

The 280hp Nemesis A, with its lightweight 202kg magnesium alloy frame, would have easily gone to speeds of over 220mph and 0-60 in well under 2.5 seconds. If it was produced pricing would have been in the area of US$45,000 / AUS$90,000 / GBP$32000. Due to poor management and other such contributing factors the company after bieng revived in the late nineties went bankrupt and this legendary superbike became just that, a legend.
