#273 SR400Custom Report

This is a hardtail SR400 ordered by a girl from Tokyo. We decided on the various parts of the menu through remote meetings with the owner via LINE and ZOOM, and when the main skeleton, such as the front 21-inch wheel, frame processing, hardtail kit, tank, rear fender, etc., was completed, we had her visit the store for position alignment, and determined the best position for the handle, seat, and step to be less tiring and easy to ride. At that time, we also discussed the design of the headlight, sissy bar, etc. to suit her taste while actually looking at the vehicle.

We balanced the entire vehicle with a 5cm fork joint to match the 13cm long hardtail at the rear, and centered around the peanut tank set at the specified position, we set each exterior at a natural mounting position while producing the whole. The chopper-like square-eyed dual lights, 60’s style up handle, and the cobra seat with a spring mount are covered with a removable fake fur cover, and the mid-high step, which makes the riding posture look cool and less tiring, and the shift is a jockey, the carburetor has been changed to FCR, adding fun to driving and operating the bike.
