Yamaha XS750 Type 11 Prototype Three

Prototype Three is the classic motorcycle in the Type 11 project by Auto Fabrica and Yamaha. Although it went into development after the two XSR900 prototypes, it shaped the design language of the project more than any other bike in the series. The base is a 1970s Yamaha XS750 with an air-cooled triple, the ancestor of the three-cylinder engine in today's XSR900. The bodywork is made entirely by hand from aluminium: organically shaped, reduced to the essentials and wrapped tightly around the frame and running gear of the classic. Tank, tail hump and the small front fairing flow into one another. For the carburettors, the workshop designed its own velocity stacks and 3D-printed them, and the hand-bent exhaust is an Auto Fabrica trademark. Prototype Three shows clearly what matters to Auto Fabrica on every project: form and function in balance and every detail thought through, from manufacturing technique and materials to the finish.
