#339 SR400Custom Report

The swing arm chopper was created for a petite girl, based on the “Bobber/Compact Chopper Complete” with seat rail drop processing.

For the petite owner, the design allows both feet to touch the ground comfortably due to the drop processing of the frame under the seat, adjusted to her height,

with a handle that is easy to operate and doesn’t tire you out on the moderately extended front fork,

and a carburetor with good starting performance, it’s finished in a way that even a girl with her first bike can ride it easily.
