Custom shop Roughchild's 'Waud Commission' began with a 1974 BMW R90/6 that was practically headed for the scrapyard. The workshop transformed this old air-cooled boxer (the 'Airhead') into a precisely engineered café racer — a machine that fuses vintage BMW heritage with modern performance, handcrafted build quality, and bespoke design.

Bringing a near-scrapped airhead back from scratch — this is the real essence of custom work. Roughchild's work has a density you'd never get on paper alone. Reconstructing a 1974 R90/6 with modern engineering, tailoring it into a one-off for the client alone. A motorcycle isn't transport, it's culture — seeing work like this reminds me of that all over again.

Going as far as custom-designing individual parts means this build must have taken a serious amount of time.

Taking an R90/6 that was basically headed for the scrapyard this far makes me rethink the airhead's value as a build platform.

Adding modern performance to a vintage frame like this is basically a redesign, not really a restoration.
