BMW R 100 GS Dirty Kini Prefers Custom Scrambler Looks Over Stock Dual-Sport Genes

No matter how many of Woidwerk’s custom two-wheeled gems we look at, our craving for more similar eye candy never seems to die down. Ralf Eggl is the sort of guy who never does things by halves, and his attention to detail is rather startling to say the least. What’s more, no two entries in his project archive are alike, because Woidwerk is all about pushing boundaries and experimenting with new things.

These are a couple of the values that led to Herr Eggl’s success on the custom bike scene, so he won’t be letting go of them anytime soon. Case in point: the handsome scrambler pictured above is unlike any other project we’ve seen from this German builder, while also bucking many of the customization trends associated with old-school airheads.

Now, there may be some well-established recipes for modifying a BMW boxer out there, yet Ralf chose to forge his own path. It all started when a client by the name of Thomas Schwarz (or The Moped Monarch, as he calls himself) visited the Woidwerk shop one day, riding a BMW R 100 GS that needed some love. He sought to get his old airhead scrambled and also freshened up with a selection of modern goodies.

Convinced that Ralf had what it took to bring his vision to life, the Monarch handed his Beemer over along with very few specific instructions on how the build should proceed. Thus, Woidwerk had quite a lot of creative freedom when it came to the finer details, but the need for improved performance was paramount and non-negotiable. Once the R 100 GS had been dismantled, the first step involved modernizing its running gear.

At the front end, the original forks were eliminated in favor of a Husaberg FE650’s modules, which provide up to 275 mm (10.8 inches) of wheel travel. They’re enveloped in black-anodized sleeves and attached to the chassis via custom triple clamps. Ralf worked his magic on the front brake, as well, installing a radial FTE caliper and a 310 mm (12.2-inch) aftermarket rotor.

Operated via a braided stainless-steel line and a billet master cylinder, these items are sure to provide all the stopping power that the Monarch could ever ask for. Things are also pretty spicy at the back, where the Woidwerk treatment saw a modern Wilbers shock absorber replacing the factory unit. Moreover, the Paralever swingarm and rear brake were both treated to a rejuvenating overhaul.

As far as the motorcycle’s footwear is concerned, Ralf kept the stock wheels but had them relaced with fresh spokes on both ends. Their rims were subsequently enveloped in dual-purpose Scorpion Rally tires from Pirelli’s catalog, offering plentiful grip both on and off the tarmac. After deleting the standard subframe, our protagonist busied himself with building a neat custom replacement from scratch.

He did so using stainless-steel tubing, while embedding an LED taillight into the rearmost portion for an ultra-clean appearance. Up top, we’re greeted by a gorgeous bench seat upholstered in a mixture of standard and perforated red leather. It’s fronted by a new alloy fuel tank that’s been manufactured in-house and polished to a mirror finish prior to installation. A tiny bit of storage space is provided by a leather pouch strapped onto the tank.

Bespoke emblems are fitted on the sides instead of BMW roundels, giving a subtle nod to The Moped Monarch. Similar detailing is present on the headlight lens, which belongs to an aftermarket LED component from Koso’s range. Mounted right below the headlamp is the tiniest front fender you’ll see all day, and there’s quite a lot going on in the cockpit, too.

A cross-braced handlebar takes up most of the space in that area, sitting just south of a multi-function digital dial supplied by Acewell. Highsider mirrors and Motogadget bar-end turn signals keep things within road-legal parameters, with the latter brand also providing the grips and rear blinkers. To avoid cluttering the new subframe, the license plate is located low down on a swingarm-mounted bracket, flanked by the Motogadget indicators.

Once he’d serviced the machine’s boxer-twin motor, Woidwerk’s mastermind added a tailor-made intake setup with aftermarket air filtration technology. This part comes with built-in red LEDs for visual effect, perfectly matching the seat upholstery and taillight to create continuity. On the other hand, the exhaust system was capped off with a premium stainless-steel muffler from Sebring.

Ralf Eggl also made a custom box for a JMT lithium-ion battery, inconspicuously stashing it right behind the air intake. With the R 100 GS scrambler completed and ready to be handed back to Thomas, the project’s author dubbed it Dirty Kini. Ironically, the Beemer actually looks downright immaculate in the photos above, but it certainly won’t mind getting all dusted up on dirt or gravel roads. A fit steed for a monarch, if you ask me.
