NSU Bison 2000

[drewpy]

This is the world’s largest single-cylinder two-wheeler. It was built by a gentleman called Fritz Langer, and it’s based on an NSU Konsul 500.

Fritz replaced the original cylinder and piston with a 122 ci unit from a radial aeroplane engine, but that piston weighed 3.3 kg—over 7 lbs. So Fritz got Mahle to make up a lightweight piston of just 1.6 kg. After the engine block was widened and the crank milled, Fritz was ready to roll.

The stainless steel exhaust system, incidentally, is 75 mm (3 inches) in diameter, and there’s no silencer. So it’ll be enough to put even a Screamin’ Eagle-equipped Harley to shame
