And I was saying a 2000cc chopper doesn't make any sense...
Check out this highly interesting website featuring a 6728cc V-Twin motorcycle, the "Gunbus" - a monster of a bike!
There are also articles on the craziest things on two wheels I've ever seen, like a four-in-line 125cc Monkey, an Enfield V-Twin, a D1200GS BMW with a single-arm front suspension, and practically anything from a steam engine powered bike with Model A wheels and tires to an electric bike with a top speed of 150mph. Here goes:

That is one crazy bike,, if you can call it bike any more,, i find one funny note in there,,, there was mentioned that is It is a little heavy at 1433 pounds so high speed corner carving might be an issue

what makes some one think that is 'Little' heavy....555555

good one KZ, fantastic reading

A friend in UK Chris Knibbs made a 6500cc V twin a few years ago using 2 cyliders from a Bristol Centaurus 18 cylinder radial aircraft engine he built stretched and widened Crank cases based on HD and Vincent parts and a Harley Gearbox. The bike runs he built his own frame . The Bike is now somewhere in NZ where he emigrated to.

There are so many fascinating stories on that website - did you read the one about the Ducati "V1"? To me that's absolutely fascinating. The guy turned the rear cylinder of a 90* Ducati V-Twin into a compressor to supercharge the front cylinder. The bike runs perfectly and has even more power than the non-charged twin! If it would be possible to build a lightweight supercharger into a motorcycle engine, we'd see 500cc twin engines with 100+ hp!
