It’s not often that we’re treated to an overtly appealing street tracker — and even rarer when the donor happens to be one of racing’s most praised KTM platforms. In an effort to bring the company’s renowned 300 XC-W Six Days chassis into the realm of street-faring stardom, David Mucci (of Moto Mucci fame) has reinterpreted the moto into his very own MM-300.
The MM-300 is a product of today’s most advanced design methods, from tried-and-true, hand-formed metalwork, all the way to carbon fiber composite that’s been modeled and cut using 3D printing. After stripping the KTM of every subframe component, Mucci took to the drawing board — constructing a 1/8″ welding wire “mock-up” to mimic the bike’s tank, side panels, and ductwork. Using the wire as a template, he transferred his finalized design to 3003-H6 0.063-inch aluminum sheet metal — creating the 300’s attractive contours, lines, and bends as he went. Moving toward the apex of the project at a breakneck pace, Mucci ran into the problem of exterior plastic shrinkage — an issue that was easily remedied by the inclusion of carbon fiber and nylon composite peripherals modeled in a CAD program and printed via a Rasie3D Pro2 printer. Each intricate piece was conceptualized to battle high heat degradation and vibration, giving the bike’s accessorized exterior a purposeful guise. Roland Sands’ 19-inch forged aluminum wheels were implemented using bespoke, custom bolt-on hubs, alongside a Ducati Brembo rotor that was contracted to replace the tracker’s 270mm KTM variant. The result: a unique street-slayer that boasts a tailored style, clean linework, and even greater attention to detail.
