The Auto Fabrica Type 11 Prototype 2 is the second of three bespoke customs built by London-based brothers Bujar and Gazmend Muharremi for Yamaha's Yard Built programme, translating the Yamaha XSR900's 900cc triple-cylinder engine into a hand-formed aluminium and carbon-fibre street machine that feels more like a moving sculpture than a production motorcycle. Priced at approximately 68,000 GBP per unit, each example is built to the individual client's specifications, making the Type 11 series one of the most exclusive custom motorcycle commissions available.
What is Yamaha's Yard Built programme?
Yamaha Motor Company launched the Yard Built initiative to channel the passion of its most creative global partners into a series of collaborative custom builds based on current production platforms. The concept arrived at a moment when hand-built custom motorcycles were reaching a historical peak of interest, and Yamaha saw the programme as a way to demonstrate the XSR900's potential as a foundation for genuine craft-level bespoke work. Auto Fabrica, founded in 2013, was one of the workshop's earliest and most celebrated contributors to the project.
How Prototype 2 sits between the three builds
The Type 11 series comprises three distinct prototypes, each approaching the XSR900 base from a different angle. Prototype 1 is a track-only machine designed with designer Toby Mellor as a pure performance exercise. Prototype 3 is the most road-functional of the trio, with a more conventional custom aesthetic. Prototype 2 sits in between: it carries BST carbon wheels wrapped in Pirelli Diablo Supercorsa V2 tyres, Brembo brake calipers, and Ohlins front and rear suspension, giving it the chassis hardware of a serious performance machine while retaining the crafted visual language that defines Auto Fabrica's approach.
Craftsmanship: aluminium, carbon, and Alcantara
The bodywork is hand-formed from aluminium bonded to 3D-printed carbon-nylon and hand-laid carbon-fibre panels. The fuel tank and front light merge into a single sculptural block, as if polished smooth by atmospheric friction. A short Alcantara-wrapped foam seat sits cleanly above the rear wheel, and the taillight assembly consists of two overlapping semi-transparent red plastic films that protrude from the rear like crystals emerging from a crack in the chassis. The speedometer, the only instrument, sits in a porthole set flush into the metal bodywork. The exhaust system follows the lower body line in a smooth arc, its exposed routing reinforcing rather than interrupting the bike's compact proportions.
