48 Cylinders!

It is a 48 cylinder, 4200cc engine made from S1/KH250 cylinders, by Simon Whitlock

Each motor is basically 8 S1/KH250 cylinders bolted on to cut up standard casings, with a 8 cyl built up crank, in turn they are bolted to a housing, gear linked and driven thru a BMW road bike gearbox, as the bike is pretty long already it would be difficult to put a transverse drive through a gearbox.

It has taken almost three years of hard work and he has overcome some huge problems to get here - where do you even start to think about building a bike like this? ... Oh, by the way, Simon is not an engineer of any kind - he oversees the building of shopping precincts etc,.

Don't look at it as a bike, look at it as a pure feat of engineering ... and Simon built a Nitrous injected, fuel injected, water cooled, supercharged H1 about 5 years ago! ... His next project may be reverting back to a small engine and gaining the maximum horsepower from it.

The bike has a small 75cc 'Donkey' engine under the seat to start it. The ignition is by 8 x 6cyl E-Type Jaguar distributers.

Oh, and not only does it run - but it is rideable - JUST! - the engine and box alone weight just over a ton!
