#189 SR400Custom Report
This custom was created based on a well-conditioned used SR400, one of the 10 types of “2%ER SR400/500 Complete Custom“, using the “B-Class Chopper Complete” as a base, and adding three options: a square 2-lamp headlight, cross mirror, and one-off sissy bar.
The style is easy to enjoy without any pressure, from city riding to camping tours, with a body that has increased straight-line stability due to the long fork, and a sissy bar that makes it easy to tie up luggage.
The selectable exterior color was finished in matte black at the owner’s request.
