	1970's Raleigh Rampar.

As you can see by the Raleigh Rampar moto-x was a big influence on early BMX bikes and that is what the kids were mimicking so what the heck... lets put some shocks on them and increase the weight!
  The double clamp suspension fork had a built in double clamp stem, actually it wasn't a stem like today's stems but instead there was holes drilled into the top fork plate which the bar clamps bolted into.  Still no metal caged pedals yet or aluminum on this baby but the seat sure was comfy.

A few of the motorcycle company's got into the act and who better to manufacture a scaled down motor-free version of their own bikes?
  The Yamaha Motobike pictured above is missing the original seat which would resemble the Raleigh's seat above and of course the tweaked out seat post is not original.  Also not original is the handle bars and grips.
  Other motorcycle company's that produced a BMXer were Suzuki and Kawasaki which had an aluminum framed version.  Still today you will find a occasional department store bike all Moto-Xed out with plastic fenders and gas tank.
