This is Part II of the F37 story that covers the design and fabrication of the thin wall chromoly road racing chassis. Construction of the engine and some racing footage aboard the finished bike can be found here in Part I.
This story highlights the creation of a road race engine from the fusion of two different enduro motors, as well as the design and fabrication of a custom racing chassis to house the “franken-motor.”
The Kawasaki A7 Avenger 350 cc rotary valve 2-stroke twin is a fun little bike.
I was surprised to find how quick these things are, and do hear they were very progressive for their time!
