Overview
Imagine a schizophrenic motorcycle, capable of changing personalities in less than an hour. That's the crazy bet that Winston Yeh, the sorcerer of Rough Crafts, took up with this Yamaha XSR 700 Yard Built. Starting from the solid base of the CP2 twin-cylinder engine, a motor as reliable as a hammer and delivering 75 horsepower, the Taiwanese preparer played the game of creative constraints: not touching the steel frame. The result? A mechanical work of art with a double edge.

The ingenious idea is this quick transformation kit. On one side, you have the Scrambler, with its lightweight Wukawa wheels, its high handlebars, and its reworked Akrapovic exhaust for a tracker style. On the other, the Café Racer, more aggressive, with its radiator fins and a hunter's stance. The whole thing rests on a common high-end base: an adaptable inverted fork, impeccable Beringer brakes, and an electronically adjustable Shark Factory X2E suspension. You go from dirt road to smooth tarmac in one click, without specialized tools. It's bespoke within reach.
Who is this hybrid creature for? The modernist customizer who wants everything, without compromise. For 12,000 euros, you are not buying a simple motorcycle, but a concept, a stylistic toolbox. The monoblock carbon fiber tank, with its small hidden fuel tank underneath, is a technical feat signed MS Pro. The finishes, like the unique paints by Air Runner, are impeccable. It's a motorcycle that speaks as much to the engineer as to the designer.
Yet, behind the magic lies a reality. This Yard Built project remains a one-of-a-kind piece, a demonstrator of what is possible with the XSR 700 platform. It makes you dream, but it will never land as is at a dealer. That's both its strength and its limit. Winston Yeh shows the way: pushed, modular personalization, almost plug-and-play. You can feel the influence of the "Guerilla Four" on the XJR, but applied to a more accessible and terribly trendy displacement.
Ultimately, this Rough Crafts Soil Scorpion is much more than a custom. It's a manifesto. It proves that with a robust mechanical base and a little audacity, a machine can have two souls. It will not convince the purist of the café racer or the traditional scrambler, but it electrifies the lover of technology and flexibility. It's a declaration of love for personalization, a motorcycle that refuses to be cataloged. And that, in a world of conformity, is quite refreshing.
