But it wasn’t just about looks; the AF1 125 boasted top-level equipment and technical excellence, making it a formidable force on the road. Its engine was a marvel, delivering a thrilling riding experience that set it apart from its competitors.
From the precision-crafted instrumentation – reminiscent of Japan’s finest producers at the time – to the exceptional electrical controls by Italy’s CEV, every detail was meticulously considered. The result was a bike that was as beautiful as it was functional.
The AF1 125 Project 108 was more than just a motorcycle – it was an experience waiting to happen.
