PURE FORM, RAW SPIRIT
R12 EARTH is a bold testament to the elegance of minimalism. Stripped down to its essential form, every line and detail serves a purpose—no frills, no distractions. The raw, brushed metal tank commands attention without shouting, its sculpted surface reflecting the purity of mechanical design.
The monochromatic palette is broken only by a subtle BMW badge and a thin accent line, hinting at the heritage behind the machine without overshadowing its custom identity. With exposed components, a clean subframe, and a tucked-away exhaust, this build reveals the beauty of engineering laid bare.
The result is a philosophy on wheels. Clean, efficient, and brutally honest, it invites the rider to connect with the road, the machine, and the moment.
REENGINEERED ELEGANCE
We have reimagined the iconic BMW R12 with a suite of meticulously crafted custom components, enhancing both its aesthetics and performance.
REDEFINING STRUCTURE
At the heart of this custom build lies its most groundbreaking innovation - the subframe with integrated subseat and a new, signature seat. Designed in collaboration between EARTH Motorcycles and the BMW engineering minds at Valta Engineering, this newly developed structure allows for an exceptionally clean silhouette - no visual disorder, no excess material. Every angle of the structure manifests precision and intent, echoing the minimalist philosophy that defines the entire bike.
-
Crafted from aerospace-grade aluminum, the subframe attaches seamlessly to the original mounting points, eliminating the need for crossbars or conventional support elements. Instead, it relies on a single, CNC-milled L-shaped structure that’s not only feather-light but incredibly strong.
-
The sub-seat structure, seamlessly fused with the subframe, creates a compact and cohesive design that flows naturally into the sculpted BMW tank. The integration of the original R12 rear light subtly honors its BMW heritage, reinforcing its identity while maintaining a clean, futuristic silhouette.
The custom EARTH signature seat is a standout detail in this minimalist build. Designed for both comfort and aesthetics, it features a sleek profile and distinctive, precision-stitched
sewing that echoes the bike’s clean lines. This unique pattern adds a tactile,
visual identity - subtle yet refined —perfectly complementing
the sub-seat structure and enhancing the overall
craftsmanship of the motorcycle.
PRECISION IN SIMPLICITY
Encased in a custom CNC-machined aluminum housing, the headlight isn’t just a functional element, it's a sculptural focal point.The precisely milled aluminum ring offers a raw, industrial aesthetic that complements the bike’s overall stripped-back look. Its brushed finish reflects light subtly, creating an eye-catching contrast against the blacked-out fork and hardware. This is design reduced to its core: no ornamentation, no excess—just pure, engineered beauty.Integrated seamlessly with modern LED technology, the headlight provides exceptional illumination while maintaining a compact and clean silhouette. It’s a perfect harmony of classic café racer inspiration and contemporary craftsmanship.
BRUSHED BEAUTY
Crafted by hand from lightweight aluminum, the front fender of our Cyber Racer model embodies the bike’s minimalist ethos. Its brushed finish adds a raw, industrial elegance, perfectly complementing the clean lines of the build.
Designed to be visually subtle yet structurally strong, it offers just enough presence without disrupting the bike’s stripped-down aesthetic—proof that even the smallest details can define the whole design.
RAW PERFORMANCE AND ESTHETICS
Constructed from high-quality stainless steel, the new EARTH exhaust features two separate silencers that not only enhance the bike’s aggressive look but also optimize exhaust flow. Each silencer is capped with precision-machined, aircraft-grade aluminum, offering both durability and a clean, refined aesthetic. This setup delivers an unmistakable sound—deep, throaty, and powerful—perfectly matching the bike’s raw character. Beyond acoustics, the exhaust contributes to improved engine breathing, resulting in better throttle response and overall performance. It’s a functional work of art for riders who demand more.
ONE FOUNDATION, THREE SOULS
At EARTH Motorcycles, customization goes beyond aesthetics—it’s about tailoring the entire riding experience. From a single custom design based on the new BMW R12, we offer three distinct models to match different lifestyles and preferences. All three share the same minimalist DNA and engineering excellence, but each tells its own story—yours to choose.

“Tu to musim este dokoncit, ale musim pripravit motorky s grafikou”
Tu by sme mohli popisat skrutky, ich dizajn, zladenie s celkovym dizajnom. Taktiez mozeme popisat “uchytenie tachometra”. Tusim ste spominali, ze mate rozne velkosti/uchytenia. Nemam vsetky informacie a tak tie sekcie naskladavam podla svojho uvazenia. Ak by ste to potrebovali rozdelit inak, dajte pls. vediet.
Tuto kombinaciu fotiek som zvolil aj z dovodu, ze tu mame rovnaky dizajn skrutiek + vzdy nejaky zltohnedy prvok aby videli navstevnici zladenie motorky v detailoch.
….tu moze byt text k nasledujucemu natocenemu pohladu motorky kde je pekne vidiet linie nadrze a sedla. Pripadne cokolvek ine k tomuto pohladu.
Tu som dal na test malu slideshow. Smerovana je k tomu aby sme ukazali hlavne casti ktore ste menili. Cize je tam farebne menena horna cast motora, vedenie hadiciek do motora, nadrz kde ste obrusili vylisovanu hranu, uchytenie sedla. K tymto castiam by mal smerovat popis. Pripadne ak chcete este nieco vyznacit, tak dajte vediet.
Ak by vas napadlo ine znazornenie menenych casti, mozeme to vyskusat.
The unique placement of the fog light switch, integrated into the center stem of the triple yokes, highlights our attention to detail. The central position makes it easily accessible while maintaining the bike's clean and uncluttered look.
Moze, ale aj nemusi byt text……Odsek
Tu je sekcia kde by sa mohla popisat zadna cast motorky, pripadne pohlady zo zadnu.
Ak sa nemylim, robili ste uchytenie znacky…
Zadna horna cast motora, ktoru ste autorsky vytvorili. Je tu vidiet rebrovanie/prieduchy. Cize moze sa uviest, ze ste neriesili len dizajn a linie motorky, ale aj funkcnu stranku odvetrania…
Details matter
Sekcia detailov. Tu sa da popisat cokolvek co vas napadne v spojitosti s detailami…..
