Behind the Momo's winning air of devil-may-care dandyism lies the rigor of 1960s Mod design: everything on it is essential to its function, without a single unnecessary flourish. As the Mods knew, such simplicity requires great discipline to achieve (think of a Vidal Sassoon hairstyle or an impeccably tailored Italian suit). To create the Momo, the designers, engineers, and craftspeople spent months painstakingly planning and executing every last detail.
