Time Traveler: Kingston Custom's Custom Yamaha TRX850 Cafe Racer

For some, the Ruhr region of Germany is defined by its industrial grit, a landscape of coal, steel, and smoke. For Dirk Oehlerking, the mastermind behind Kingston Custom, Gelsenkirchen is a sanctuary of craftsmanship. It is a place where the down-to-earth nature of the people matches the honest, mechanical integrity of his buildings.

Dirk is no stranger to the winner’s circle. He began his obsession in Hanover, famously running away to his first motocross race and returning with a trophy while wearing rubber boots. By 1985, he was a German champion competing on the world stage, eventually amassing over 230 awards. But Dirk’s talent isn't restricted to the dirt; his background in the elite ‘Styling Garage’ in Hamburg, customizing luxury sedans, gave him the surgical precision required for world-class builds. Today, he is a household name in the custom scene, known for a design language that is as sophisticated as it is soulful. His latest commission takes a 1990s Japanese cult classic and drags it back to a more analog era.

The Yamaha TRX850 was Japan’s answer to the Ducati 900SS. Launched in the mid-90s, it was a sensible sportbike with a wild heart. Its 849cc parallel-twin featured a 270-degree crankshaft, a move designed to mimic the power delivery and "thump" of a 90-degree V-twin.

Wrapped in a lightweight steel trellis frame, the TRX was a handler’s dream, producing 83 hp and 62 ft-lb of torque. While the factory model had a distinct 90s half-fairing aesthetic, the bones were pure racer. It was the perfect canvas for a client who had owned his TRX since it was new in 1997 and wanted to see its completely original form transformed into something timeless.

The project began with a total teardown. To move away from the 90s plastic feel and toward the warmth of the 1970s, Dirk focused on the chassis finish. The trellis frame was peened, polished, and nickel-plated. Unlike the traditional brightness of chrome, nickel offers a golden, vintage hue that serves as the backbone for the entire aesthetic.

The geometry was sharpened by shortening the front forks by 50 mm. This gives the TRX a predatory forward lean and a "fast while standing still" silhouette, bolstered by a custom-made YSS rear shock. While the 849cc engine remains largely internal-spec, Dirk swapped the factory fueling for a Mikuni TDMR40 carburetor from Topham, sharpening throttle response to match the bike's aggressive new look.

To further shift the stance, Dirk ditched the stock cast-aluminum wheels. In their place sits an unlikely custom wheelset that works perfectly: a Yamaha XS650 hub up front and a Yamaha XT600E hub at the rear, laced to 17-inch rims. Shod in Bridgestone rubber (120/60ZR17 front and 160/60ZR17 rear), the new rolling stock instantly ages the bike in the best way possible.

The bodywork is an exercise in metal shaping. Dirk hand-hammered the fuel tank from 2 mm aluminum, retaining the 3.5-gallon capacity of the original but refining the lines to flow seamlessly into a custom aluminum seat cowl. The cowl is capped with a rich brown leather pad, providing a warm, organic touch against the metallic finishes.

Up front, a handcrafted fiberglass café racer fairing, traditionally inspired but modern in execution, houses a 5 3/4-inch Bates headlight and a KOSO digital/analog hybrid speedometer. The choice to show only speed on the digital display while keeping a large analog tachometer preserves that 70s cockpit feel.

The final flourish is the "Blackstorm Metallic" paint, accented by fine gold pinstriping that traces a path from the fairing to the tail. These gold accents are echoed in the brake calipers and rotors, tying the build together with a level of cohesion that explains why Kingston Custom remains at the top of the global hierarchy.

It’s a rare feat to take a child of the 90s and blend it with the soul of a 70s powerhouse without losing the bike's inherent identity. By stripping away the plastic era of the TRX850 and leaning into the warmth of nickel-plating and hand-formed aluminum, Dirk Oehlerking has bridged a thirty-year gap in motorcycling history. The result isn't just a nostalgic tribute; it’s a refinement of the Yamaha that feels more factory than the original. In the industrial heart of Gelsenkirchen, Kingston Custom has once again proven that while trends may shift, the combination of a champion’s instinct and a master’s touch is truly timeless.
