Yard Built XSR900 ‘Monkeebeast’ by Wrenchmonkees


Custom motorcycle builders the Wrenchmonkees are not only at the heart of the custom scene, they are also at the heart of Yamaha’s Yard Built activities. From their Copenhagen workshop the Danish duo have been responsible for a string of stunning builds from the Sport Heritage range, including the XSR400, XJR1300 and now, the XSR900.

Delivered in their trademark black, the Yard Built XSR900 ‘Monkeebeast’ ups the game and breaks from tradition. This is no run-of-the-mill cafe racer or brat style machine but a brutal brawler, an urban warrior built to tackle any terrain.


Taking the XSR900 from a street machine to an all-terrain beast comes courtesy of Borrani 17″ spoke wheels with black rims, 9mm stainless spokes and black hubs. The Borrani wheels get wrapped in some serious rubber, Continental TKC tyres. The rear-end gets beefed up with a K-Tech shock, Gilles Tooling chain adjusters and a TRW rear brake disc and steel braided brake lines.


The rider position is dealt with by adding a Wrenchmonkees one-off seat, Gilles Tooling rearsets modified with enduro footrests, a Magura handlebar and Biltwell Renegade grips. Braking at the front gets an upgrade with a Nissin radial front brakemaster and steel braided brake lines. Motogadget pushbuttons clean up the contact point and an MT-03 style headlight and LED rearlight shine out.


A growling SC Project exhaust caps a modified MT-09 system and Wrenchmonkees one-off aluminium rear fender, front fender and engine guard complete the custom look. Powdercoated fenders, engine guard and tank covers wrap up the design, leaving the Monkeebeast ready to roll.

Selected parts designed for the Monkeebeast will soon be available directly from the Wrenchmonkees for those XSR900 owners who want to make a different statement with their machine.
