Martin RoadRunner

Martin Road Runner Chassis

  Martin Manufacturing Company located at 113 W. Magnolia Blvd. in Burbank, California produced the Martin Roadrunner in 1947 and 1948.  The Martin Roadrunner only came as a rolling chassis.  Martin Roadrunner was designed to be compatible with motorbike engines offered by  Whizzer,Marmin, Briggs & Stratton. If you look closely at the design, you will notice how the Martin Roadrunner chassis and fork differ from other motorbike cantilevers frames from the same era like the the Schwinn WZ507 Whizzer (later designed as the S4).  The Martin Roadrunner is "bump start"- starts by pushing, or using a kick or pull starter so the motorcycle doesn't have a crankset/pedal/drivetrain system.  

The frame is also designed so you can use 24" or 26"  wheelbase. The Martin Roadrunner features a unique spring fork to improve the overall riding quality and smoothness on the road.   The fork shown in the picture above is the incorrect fork.  The picture below is an original Martin Road Runner Spring Fork that was also offered as an aftermarket fork for motorbikes.

  • Electronically welded all steel tubular frame designed by aircraft engineers
