When BMW Motorrad pulled the silk off the R nineT in 2013, it was a pivotal moment for the custom scene. Designed as a "blank canvas," it arrived just as the "New Wave" cafe racer movement was reaching a fever pitch. We first looked at our favorite R nineT customs nearly ten years ago, but in the world of custom fabrication, a decade is a lifetime. Since then, the platform has evolved from a trendy retro-roadster into arguably the most versatile base in motorcycling history.
Over the last ten years, the R nineT’s air-cooled Boxer engine and modular chassis have been poked, prodded, and completely reimagined by the world’s elite builders. From monocoque masterpieces to sci-fi cruisers, these bikes represent the pinnacle of modern craftsmanship. They aren't just motorcycles; they are rolling proof that the Boxer twin is one of the most resilient icons of the 21st century.
Here are eight of the best BMW R nineT customs featured on Bike EXIF over the last ten years.
Rough Crafts: The "Bavarian Fistfighter"
Winston Yeh of Taiwan’s Rough Crafts has a signature aesthetic that is almost impossible to replicate. When BMW Motorrad Taiwan approached him for an officially endorsed "Soul Fuel" build, Winston decided to blend the brand’s rich history with his own dark, aggressive style. The result is the "Bavarian Fistfighter," a machine that pays homage to the legendary R 90 S while looking like it belongs in a high-speed street brawl.
The bodywork is a class in aluminum shaping. The fuel tank borrows lines from late-70s "Airheads," but hides modern essentials like the fuel pump and electronics. Up front, a nose fairing reminiscent of the R 90 S houses a perforated section to feed air to the oil cooler. The solo seat pays tribute to the rubber BMW seats of the 1950s, though it is wrapped in premium leather for a modern touch.
The bike sits on custom Rough Crafts "snowflake" wheels and features top-shelf hardware like Beringer controls and a Gears Racing rear shock. To finish it off, Winston applied his trademark black-on-black paint, but with a twist: a carbon fiber texture visible beneath the black candy paint, accented by silver leaf pinstripes. It remains one of the most cohesive R nineT builds ever created. [MORE]
Sinroja Motorcycles: "Moksha"
Rahul and Birju Sinroja of Leicester-based Sinroja Motorcycles are known for their engineering precision. When they were tapped by Dutch watchmaker TW Steel for the "Son of Time" project, they decided to break the mold of traditional cafe racer design. The bike, named "Moksha" (Sanskrit for freedom), was built in a grueling ten-week window with design input from Rajesh Kutty of Bentley Motors.
The most striking feature is the front fairing, which looks like a 3D optical illusion inspired by the artist M.C. Escher. Hand-shaped from aluminum over 150 hours, it utilizes only two mounting points and features air scoops inspired by BMW M-series cars to cool the cylinders. The fuel tank and tail section were equally labor-intensive, with a custom gas cap designed to mimic the crown of a TW Steel watch.
Underneath the jewelry, Sinroja binned every piece of unnecessary Euro compliance gear and fitted a custom Nitron shock and Kineo wheels with red-anodized nipples. A custom GPS speedo from Speedhut replicates the watch face, and an in-house stainless exhaust provides the soundtrack. Moksha isn't just a show bike; it’s a functional statement of liberty that pushes the R nineT into the realm of high art. [MORE]
Gunn Design: "Maxx Headroom"
While many customs are destined for the showroom, Dan Riley’s "Maxx Headroom" was built to be thrashed. A freelance designer operating as Gunn Design, Dan was challenged by Ola Stenegärd to create a flat track weapon out of an R nineT Pure. The result is a raw, purposeful "hooligan" racer that has seen more track time than most production bikes see in their lifetime.
Dan swapped the stock tank for a 1990 Honda CB400 unit, which required welding the OEM bottom section to the Honda shell to maintain the fuel pump's functionality. The rear features a carbon fiber flat track tail on an abbreviated subframe, topped with a Saddlemen seat pad. Woody’s Wheel Works provided the essential 19-inch flat track wheels, which were squeezed into the frame after some clever rim-width adjustments.
Performance was boosted via a RapidBike Tuner to account for the MX-style Rocket Exhaust and K&N filters. With ProTaper bars, Rox risers, and the ABS system deleted, the bike is a visceral, lightweight machine designed for maximum control in the dirt. Maxx Headroom proves that even the sophisticated R nineT can be stripped down into a gritty, podium-chasing racer. [MORE]
DNA Filters: "BCR-018 Billet Sting"
Dino and Marios Nikolaidis of DNA Filters decided to celebrate their expertise in airflow by building a bike that challenges the laws of physics. The "Billet Sting" features a honeycomb monocoque chassis CNC-milled from ten massive billets of 6082-T651 aluminum. It is a staggering display of engineering that replaces the traditional trellis frame with a high-strength, lightweight exoskeleton.
The bike’s intake system is its most radical feature: two 23-inch hexagonal tubes that channel air to DNA filters housed in transparent Lexan airboxes. At speeds over 100 mph, these tubes provide increased pressure to the 122-hp engine. The power is managed by an Akrapovič titanium exhaust system and a Plex Tuning 4.3” TFT telemetry display that tracks every data point coming from the ECU.
The suspension is equally exotic, featuring a custom Z-shaped swingarm and "right way up" Hyperpro forks. Every detail, from the vertebral-column-style oil cooler to the honeycomb-grill mufflers, was designed to push manufacturing limits. The Billet Sting isn't just a motorcycle; it’s an engineering manifesto that proves the R nineT can be a platform for genuine technological innovation. [MORE]
Zillers Garage: The Retro-Futurist
Dmitry Golubchikov of Russia’s Zillers Garage is a world-class builder who creates machines that look like they were pulled from a 1930s science fiction novel. This R nineT, commissioned by BMW Motorrad Russia, took ten months of solo fabrication. Almost nothing remains of the original bike besides the engine and final drive, as the entire machine is now encased in hand-formed aluminum bodywork.
The bike’s silhouette is defined by its lack of a kickstand. Instead, it features a custom-built pneumatic suspension system that lowers the bike until it rests on its belly pan. When it’s time to ride, a button on the integrated cockpit—which also houses a Motoscope Mini speedo—activates the hydraulics to lift the bike to riding height. The 18-inch wheels are fully custom, designed to look like jet turbines.
Beyond the aesthetics, Dmitry’s craftsmanship shines in the details. The hydraulic clutch and brake master cylinders were machined from scratch, and the wiring loom is entirely new. Wrapped in a muted monochrome grey with subtle silver pinstriping, the Zillers R nineT is a reminder that the most memorable bikes are those that throw the rulebook out the window. [MORE]
Engineered To Slide: The R nineT Chopper
Nigel Petrie of Australia’s Engineered To Slide is a master fabricator who specializes in the unconventional. In 2019, he unboxed a brand new R nineT Racer and decided to see if he could turn it into a skinny, elegant chopper. The resulting build is a skeletal masterpiece that combines old-school geometry with 21st-century materials.
The centerpiece is the chromoly girder fork, which features a "spring" made from five layers of vacuum-baked carbon fiber. The front wheel is a massive 22-inch hoop wearing a Model T Ford tire, while the rear is an 18-inch drag slick. Nigel even ditched the factory fuel injection in favor of a Morris Magneto and Smart Carbs, giving the modern Boxer engine a raw, analog feel reminiscent of a 1960s dragster.
The frame is a completely custom chromoly hardtail, with the engine "hung" inside to maintain the classic chopper lines. Nigel also fabricated heel-operated controls to keep the bars as clean as possible. It is an "intriguing mix of high- and low-tech" that proves the R nineT can be anything a builder has the patience to imagine—even a fire-breathing, hardtail lane-splitter. [MORE]
FabMan Creations: "Storm"
Wayne Buys of South Africa’s FabMan Creations is a self-taught metal shaper who built this aircraft-inspired R nineT using a homemade English wheel and a tree stump. Working without sketches or templates, Wayne spent eight months hammering aluminum panels into an interlocking "Meccano set" that covers the entire motorcycle. The result, dubbed "Storm," looks like it belongs on the deck of a 1940s aircraft carrier.
The bodywork isn't just decorative; every vent is functional. Massive side ducts cool the Boxer engine, while small intakes on the front fender direct air to the brakes. Wayne even relocated the oil cooler and kitted it with a fan to ensure the bike survives the South African heat. The exhaust is hidden within the belly pan, exiting through stealthy ports on either side.
The controls are equally impressive, featuring raised aluminum clip-ons with all wiring and cabling hidden internally. Wayne also fabricated reverse levers and an internal throttle, keeping the cockpit clean and centered around an Acewell speedo. Storm is a testament to what a single, determined builder can achieve with a hammer, a wheel, and a vision of retro-futuristic speed. [MORE]
Smoked Garage: The "Batcycle"
Batman and his motorcycles have been a pop-culture staple for decades, and Nicko Eigert of Smoked Garage in Jakarta decided to bring that fantasy to life. Commissioned by a client with a childhood dream of riding a Gotham-style machine, Smoked created a brooding, angular R nineT that balances "The Dark Knight" aesthetics with real-world rideability.
The bodywork consists of a hand-shaped carbon fiber fuel tank and tail unit, paired with a complex array of aluminum fairings that envelope the lower half of the bike. The matte and gloss black finishes are accented by exposed carbon fiber, giving the bike a modular look that mimics modern Batman utility belts. A large windscreen and a utilitarian LED headlight complete the "Caped Crusader" silhouette.
While the exterior is all drama, the internals remain street-legal and capable. Smoked upgraded the OEM forks and fitted an adjustable rear shock to handle Jakarta’s streets. With handmade tapered mufflers and "murdered out" engine covers, the bike is a shadow in the night. It is a rare example of a themed build that remains a high-performance cafe racer at its core.
