The folks at Diamond Atelier made a name for themselves with some truly fascinating custom conversions, mainly focusing on BMWs new and old. You will also see them building the occasional restomod here and there; something along the lines of this rad 1990-model R 100 GS. The donor was in near-perfect condition with a mere 37,000 km (23k miles) on the odo, so the decision to have it customized may stir some controversy.
Nonetheless, it can hardly be denied that Diamond Atelier came up with an incredible piece of machinery, one that clearly warrants a closer look. That being said, let’s go ahead and see what they’ve been up to here, starting with the frame surgery which took place right after the initial teardown. The subframe was shortened by about two inches (50 mm) to tighten up the bike’s rear-end proportions.
An unnecessary tabs were shaved off the rest of the chassis, and the entire framework was ultimately powder-coated black. Next up, the rear tubing was topped with a custom-made saddle, featuring black leather upholstery and plentiful padding. Right in front of it lies the repurposed fuel tank of a different R model, but all the other bodywork you’ll see here is original.
Small tweaks were still needed, though, and the rear fender was raised ever so slightly to create a straight line from the tank to the tail section. The BMW’s suspension underwent a comprehensive makeover, as well, with an adjustable Wilbers shock absorber replacing the stock unit at the back. On the other hand, the OEM forks have been retained and fitted with progressive springs.
Improved front-end stopping power is made possible by four-piston Brembo calipers and twin wave-style rotors measuring 320 mm (12.6 inches) in diameter. The calipers are held in place via custom billet aluminum brackets, and they’re operated by way of braided stainless-steel brake lines from ABM. Unsprung territory is home to aftermarket wheels cloaked in Metzeler Roadtec 01 rubber.
The new rims measure 19 inches up north and 17 inches at six o’clock, both laced to stainless-steel spokes and covered in black powder coating. In the cockpit, there is a fresh Magura handlebar placed above a CNC-machined top clamp, sporting a single underslung mirror on the left-hand side. An auxiliary fog lamp can be spotted lower down, neatly perched on the left crash bar.
Small LED turn signals are attached to the lower triple clamp, and they’re hooked up to a fresh wiring harness just like all the other electronics. The engine was rebuilt and then fitted with some new breathing equipment, comprising K&N air filtration hardware and modified exhaust pipework. Lastly, Diamond Atelier had the bodywork painted in a stylish white and blue color scheme, thus taking the customization process across the finish line.
