#89 SR400Custom Report
This chopper was built to look its best when ridden by a well-built owner, matching the owner’s personality and height.
The model is based on the British choppers of the 60s and 70s.
The frame under the seat has been modified in the style of BSA, with a gas tank repurposed from BSA, fenders with center ribs at the front and rear, and various parts such as the headlight/light stay. The details of the mounting stays were selected and produced to have the atmosphere of a British car.
The sissy bar and muffler are in the style of the choppers of yesteryear.
The frame is painted with meteor flake paint, and each part is finished with chrome plating or polishing for a dazzling finish.
The wheels are the standard size of 18 inches front and rear, but have been replaced with iron-plated rims.
