As the name implies, Radical choppers are over-the-edge creations incorporating lots of custom machine work and lavish paint jobs. Their frames and sheetmetal are rarely straight from a factory or catalog; they're usually modified or handmade and thus unique.
The "manufacturers" can be companies making a few bikes a year for well-heeled buyers, or backyard builders toiling on their own creations. But the bottom line is that the best of these stretch the imagination -- and sometimes, the limits of reason.
