some of those bikes are real pieces of work. (and at least one is just for show unless it's got solid rubber tires under all that weight!) i tip my hat to the people out there who cram extra cylinders on an existing engine. (along those lines, somewhere in europe a guy welded up a vespa parallel twin: 400cc, 25hp of screaming fury.)

there were a few boss hosses on display at the motorcycle show up here a few months ago, and one of the large block models had a nitrous setup that gave it something like 800 hp. wtf is up with an 800 hp bike? if i had throwaway money like that i'd rent out the vomit comet.
