The motorcycle experts over at Wrenchmonkees are not only renowned on the custom scene, they're also at the heart of Yamaha’s "Yard Built" project - a unique way to get independent customizers involved in creating new bikes and selling to the manufacturer's loyal customers.

From their Copenhagen workshop, the Danish duo have been responsible for a string of stunning builds from the Sport Heritage range, including the XSR400 and XJR1300. Now they're back with a stunning adaptation of the XSR900.

Delivered in trademark Wrenchmonkees black, the "Monkeebeast" ups the game and breaks from tradition. This is no run-of-the-mill cafe racer, this is a backstreet brawler, an urban warrior built to tackle any terrain. Borrani 17″ spoke wheels with black rims, 9mm stainless spokes and black hubs provide the stability; while Continental TKC tires, a K-Tech shock, Gilles Tooling chain adjusters, and a TRW rear brake disc provide the traction.

A screaming SC Project exhaust caps a modified MT-09 system, and a Wrenchmonkees one-off aluminum rear fender, front fender and engine guard complete the shiny-but-rough look.

Selected parts of the bike are available now over at the Wrenchmonkees web store as part of Yamaha's "Yard-Built" project.

Meanwhile, this is the world’s first 3D-printed motorcycle.
