Moto-Bike Models

Yamaha’s Moto-Bike was made for three years (1974-1976). There are differences between the model years that makes it easy to identify what year a moto-bike was made. A good collection of photos can be found at BMXmuseum.com.

1974 (A Model):

  • Solo saddle with “MOTO-BIKE” silkscreened on back.
  • Cottered crank
  • Rubber pedals
  • The lower body portion of the fork was painted to match the frame.
  • The rear fender,  chain guard & handlebars were chrome plated.
  • Serial number is stamped on bottom side of bottom bracket.

1975 (B Model):

  • Same as A Model except…
  • Banana seat. The top shock mounting point on the frame was lengthened to provide an anchor point for the seat brace.
  • The handle bars and the chain guard were painted flat black instead of being chromed.

1976 (C Model):

  • Same as B Model except…
  • Single piece crank.
  • Rat trap pedals
  • The fender and chain guard are made of plastic instead of steel.
  • The fork legs are polished aluminum instead of painted steel.
