#88 SR400Custom Report

This is an SR customized in a 70s style.

We had a detailed discussion with the energetic owner and created the position and style.

We recreated the overall silhouette, the way each part is attached, and the details to match the atmosphere of the custom bikes of the time to the SR engine, and finished it in a chopper style that was not found in past SRs.

The vintage coffin tank is welded & molded to the frame.

This is a setup filled with the owner’s relentless spirit to live life to the fullest.

Although the customizing, painting, and finishing of each part are still in progress,

The unfinished roughness is also completed as a style.

This kind of chopper is a mental vehicle.

Without relying on Harley or foreign car brands, we made it with the owner’s feelings in the mass-produced SR

It’s a chopper that only suits the owner, made just for the owner.
