The 1990 BMW R100GS by Diamond Atelier is a restomod that sits perfectly between vintage character and modern performance. Starting from a remarkably clean, first-owner R100GS, builder Tomas Konecny resisted his usual radical approach and instead refined the classic airhead boxer with subtle, period-correct upgrades, creating what he calls "the best performing airhead BMW" he has ever ridden.
Diamond Atelier loves BMW motorcycles and if you scroll through their previous builds you will find a generous amount of Bavarian machines. This time, their build takes a different approach.
What makes this 1990 BMW R100GS special?
They started with a 1990 BMW R100GS and decided to upgrade it and keep it period correct at the same time. Matter of fact, these bikes have seen such extensive customizations that it is hard to see something new built on them. So they went against the grain and decided to keep the upgrades as subtle as possible, including a Wilbers Nightline suspension system, short subframe, ABM lines, and a CNC machined fork brace. The donor was a shockingly clean, first-owner specimen with only 37,000 km on the clock, as Silodrome reported. The result is a bike seemingly frozen in time, without the advancements of technology and design but with all the flair of a classic motorcycle.
Custom or restomod: where does it land?
Tom kept the bulk of the bodywork original, though he swapped the stock tank for a Monolever cell raised slightly at the front and lowered at the back to achieve a dead-straight line through the tank and seat. The revamped GS now rides on modern spoked wheels wrapped in Metzeler Roadtec rubber, landing it halfway between a full custom and a faithful restomod, as autoevolution noted. The goal, in Konecny's words, was to chase the timeless feel of a Porsche 911 or a Rolex Submariner, a classic that ages gracefully rather than chasing trends.
