The Nemesis from the late 1990s would surely have ranked higher if it had reached production, as its specs were scintillating. Its 1500cc V-8 was said to be capable of spinning to a stratospheric 17,000 rpm where it was claimed to produce 290 hp. Most of the engine’s tooling had already been produced for Norton’s 750cc inline-Four Manx project, so engineer Al Melling came up with the idea for the V-8 using a pair of the Four’s cylinder banks. It was to be underpinned by a cast magnesium frame.

Sadly, neither the Manx nor the Nemesis came to fruition, as this was a complicated era in Norton’s history when several independent entities had vested interests in the then-defunct marque. The Nemesis was an adventurous moon shot that unfortunately became stillborn and just a footnote in motorcycle history. The prototype and a test engine currently reside at the National Motorcycle Museum near Birmingham, England. The video below details much of the bike’s history and development, including a run on a dyno that sounds delicious even if it was only run to around 8500 rpm.
