#266 SR400Custom Report
This is an SR400 that has been transformed into a B-class chopper style using original bolt-on parts, while keeping the normal frame (only the turn signal stay part of the rear frame is cut). With a long fork, rear low down, rear 16-inch kit, a Sportster tank with aging paint by “BACON“, a thick button-down seat, and a drag pipe muffler, we have set a good balance of standard parts. We added an FCR carburetor for an acceleration that you wouldn’t expect from an SR, and the handle/step/seat is set in a position that is easy on the body according to the owner’s physique. We used a number base with a tail and an adapter to set on the back of the sissy bar, which we launched as a new product this time, on the front and rear fenders that are just the right length to suit any style.
