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.
• BMX knobby tires instead of the older diamond tread “Tractor grip” tires on the A & B models.
