When Yamaha launched the XSR900 in 2016, it wasn't just another retro bike; it was a Trojan Horse. Beneath the 1970s-inspired fuel tank covers and round headlight sat the heart of a hooligan: the 847cc (and later 890cc) CP3 inline-triple. This 'Crossplane Concept' engine is widely regarded as one of the most charismatic powerplants in modern motorcycling, offering a linear torque curve that makes front wheels feel remarkably light and an intake howl that is purely addictive.
The XSR900 was the flagship of Yamaha’s 'Faster Sons' philosophy, a blend of heritage styling and the cutting-edge chassis of the MT-09. However, for all its performance, the stock bike is often criticized for a busy aesthetic, cluttered with plastic brackets and messy plumbing. This imperfection makes it the perfect canvas for custom builders. From bolt-on kits that transform its silhouette to full-fairing recreations of 90s GP legends, here are six of our favorite Yamaha XSR900 customs featured on Bike EXIF.
The "Guerrilla" Street Tracker by Rough Crafts
Winston Yeh of Rough Crafts is known for a dark, brooding signature style that transcends genres. When he tackled the XSR900, he chose to ignore the 'Faster Sons' retro-roadster vibe in favor of a menacing, unapologetic street tracker. The goal was twofold: create a show-stopping machine and develop a comprehensive bolt-on kit that fans could install at home without touching a grinder.
The kit features carbon fiber tank covers that interface perfectly with the stock frame and a tracker-style tailpiece that bolts to the OEM subframe with just two fasteners. Up front, a carbon fiber headlight nacelle lowers the stock gauge for a sleeker profile. The running gear received a massive promotion via a set of Öhlins FF521 forks, held by custom triples, and a custom Öhlins rear shock.
To shave weight and add "pop," Winston fitted carbon fiber wheels from BST and a full SC Project exhaust system. Finished in Rough Crafts’ signature black-on-black with subtle pinstripes by Line & Circle, this build proves that the XSR900’s messy packaging can be cured with the right set of carbon fiber panels and a heavy dose of aggression.

The Minimalist XSR by Bunker Custom Cycles
Not every custom build needs to be a radical departure from reality. The Uzer brothers at Bunker Custom Cycles in Istanbul took a more surgical approach for their XSR. Their goal was to enhance the XSR900’s natural lines using a less is more philosophy, resulting in a bike that looks like a factory special edition.
The centerpiece of the build is a set of carbon fiber fuel tank covers that change the bike's silhouette in minutes. They replaced the bulky stock lighting with a custom tail tidy, an aluminum blank-off plate, and a stubby high-mount front fender. These small changes, paired with EBC floating rotors and a silver-and-blue livery, give the bike a rugged, 'scrambler-lite' feel.
By keeping the frame and the CP3 engine stock, Bunker highlighted the XSR's inherent strengths while fixing its most glaring aesthetic flaws. It serves as an inspiration for the everyday rider who wants a unique machine without a year of downtime in the garage. [MORE]
The 'CP3' Concept by JvB-Moto
Jens vom Brauck of JvB-Moto is a purist. His XSR900, titled ‘CP3,’ is a minimalist masterpiece that sheds 20 kilos (44 lbs) from the stock machine. Jens ignored the "dangerous insect" look of modern naked bikes, opting instead for a "reduced and purposeful" design inspired by concept cars of the 70s and 80s.
The JvB-Moto transformation includes proprietary tank covers, a unique LED headlamp unit, and a bolt-on tail section that gives the bike a monocoque look. Perhaps the most striking feature is the sheathed wheels; the stock rims are covered in custom carbon fiber discs, a signature JvB move that adds aerodynamic heft to the visual profile.
Performance is bolstered by a Termignoni exhaust (adding 4 hp) and Beringer brakes. Clad in a matte, ultra-dark Yamaha Racing blue, the CP3 feels like a futuristic prototype. It moves the XSR900 away from the cozy retro niche and into the realm of timeless, clean performance. [MORE]
The 'XZR900 Thunderbolt' by HAXCH Moto
Marc Bell of HAXCH Moto is a master of the 90s sportbike revival. While most XSR customs go the tracker or café route, Marc saw the triple as the perfect heart for a '90s endurance racer homage. The XZR900 Thunderbolt is a handcrafted aluminum tour-de-force, featuring a full fairing, a blocky tail section, and a deeply sculpted tank cover that channels the spirit of the YZF750 and YZR500.
Marc’s fabrication skills are on full display here; the aluminum bodywork was shaped using an English wheel to fit the narrow XSR frame. Beneath the skin, the bike is a serious performer, featuring Maxton Suspension, Dymag three-spoke wheels, and HEL Performance braking components. A remap by Seton Tuning unlocks an extra 10 percent of power from the triple.
The livery is the final nostalgic punch, vivid shades of purple and teal that would look right at home at a 1992 Suzuka 8 Hours race. This build isn't just about looks; it was a prototype for a limited production series, bringing factory-level craftsmanship to the neo-retro scene. [MORE]
The 'Æon' by Diamond Atelier
Occasionally, a builder tries to break the mold entirely. Diamond Atelier did just that with ‘Æon,’ a bike built for watchmaker TW Steel. The most radical feature? A massive gap where the fuel tank should be, exposing the organic shape of the frame hugging the engine, much like the skeletonized dial of a mechanical watch.
To achieve this uncluttered look, Diamond Atelier cut an incredible 100 meters (328 feet) of wiring from the stock harness. The actual fuel tank is a tiny three-liter unit hidden within the bodywork. The styling, all edgy panels and exposed rivets, is a nod to Japan’s Bōsōzoku car culture.
The bike sits low on ABM Multiclip handlebars and Pirelli slicks, giving it an aggressive, crouching stance. While arguably the least practical bike on this list, Æon is a pure styling exercise that pushes the XSR900 into the realm of high art, exposing the mechanical core of a modern production motorcycle.

The 'Carbona XR9' by Bottpower
If you want to see how a MotoGP-spec engineer approaches the XSR900, look no further than David Sánchez and Bottpower. Inspired by their Pikes Peak-winning BOTT XR1R, the XR9 Carbona is a supermoto-style predator. The design pushes the visual mass forward, creating a "pit bull" stance with muscular carbon fiber fuel tank covers and integrated air intakes.
This isn't just a styling exercise; the prototype features Ceracarbon carbon fiber forks with Öhlins TTX cartridges, Rotobox BOOST carbon rims, and Bridgestone race slicks. The cockpit is equally high-end, utilizing composite TA-KE handlebars and Brembo controls. For those who want the look without the five-figure suspension bill, Bottpower offers the bodywork as a plug-and-play kit compatible with the MT-09 and Tracer 9.
To prove the kit’s versatility, Bottpower built a second street version in white, complete with turn signals and road tires. Whether in full-race trim or street-legal guise, the XR9 is a masterclass in 3D CAD design and carbon fiber fabrication, turning the triple-cylinder Yamaha into a high-tech weapon. [MORE]
