#230 SR400Custom Report
This is a hardtail SR400 chopper style ordered by a female hairdresser from Okayama Prefecture. With a height of 150cm and a delicate frame, it is designed to be easy to ride even for owners without arm strength, with special features in each part to make it enjoyable for a long time without strain.
The overall styling was mostly left up to us after hearing a rough image. To suit the tough yet cute owner covered in tattoos, we finished it with a narrow triple tree front, 19-inch mini drum wheel, up-sweep muffler with ripple pipe, and separate high back seat. The styling is also compatible with the owner’s future ideal of long fork conversion.
The unique aged paint with a scratched feel is by “BACON“. We finished it with a paint job that took into account the owner’s wishes.
