#144 SR400Custom Report
This is an SR400 customized based on the “B-Class Chopper Complete” made by customizing a used SR400/500 from 2%ER, with options such as a 16-inch cast rear wheel and aging paint by “BACON” added.
The swing arm extension work is also an optional specification to match the large owner.
With a long wheelbase and comfortable positioning of the handle and step, and the replacement of the FCR carburetor, you can ride easily and quickly.
Considering straight-line stability and low-speed handling with setups such as fork extension, rear lowering, tire diameter, etc., it is easy to operate in the city and on highways, and the convenience of being able to handle everything from shopping to long touring lightly with the attachment of a sissy bar is also a point.
We made it as a chopper style that you can ride casually.
