Scrolling through my social media feed, I kept coming across motorcycles I couldn’t help but save. The algorithm had me hooked, serving up one stunning machine after another, and each and every one of them was from Classicbike-Raisch. Founded by Rainer Schenk and now guided by his three sons, Christopher, Henrik, and Yannic, the Rheda-Wiedenbrück workshop has spent nearly two decades refining modern classic Triumphs with a distinctly German approach: engineered to perfection. Their latest project makes that philosophy clear. Turning their attention to the homegrown BMW R12, the Race Cruiser concept is available in two configurations: a focused single-seat version and a versatile double-seat model for a more relaxed approach to custom cool.
Back in 2007, when Rainer founded the company, the BMW heritage range was yet to emerge, so it made perfect sense to focus on the Triumph product from nearby England. Classicbike-Raisch found its foothold by supplying to their local market three things: the best aftermarket parts from around the world, their in-house range of high-end products, and incredible custom builds that get every Triumph fan hot and heavy under the collar. And just like the two bikes before you, a complete machine can be ordered directly from the Raisch workshop, fully street legal and TÜV approved, with each build tailored to the customer’s brief.
And so, having conquered the Triumph market, the family decided to start working with the local BMW brand, and true to their retro roots, the BMW R nineT made for the perfect foundation, and the R12 the obvious successor. Each R12 Race Cruiser starts with a 17-inch wheel conversion, using either high-quality Kineo spoked rims or ultra-light forged aluminium rims, which dramatically reduce the unsprung mass. Then on goes the fat Pirelli SuperCorsa rubber, offering boatloads of grip and available raw, or with the white sticker pack for the boy racer vibe.
A purpose-built front mudguard ties the conversion together with form and function, and it’s a hell of a lot nicer piece than the strange stock unit. Then, everything that can be blacked out has been, and here you see the guys deploy a host of their high-end, in-house parts. An oil filler plug and machined reservoir covers take care of the little things, while a frame plate cover, a stunning radiator guard and rear eliminator kit really clean up the lines of the bike. The injection-moulded throttle covers on the double-seat BMW are a brilliant addition and prove Classicbike-Raisch can work with any material and techniques, old and new.
From there, the details begin to separate the two personalities. The single-seat version leans harder into the race concept. Its tail treatment tightens the rear profile, eliminating visual weight and reinforcing the solo intent. The exhaust choice here comes from Unit Garage, complementing the striped silhouette with a more classic endurance tone and GP-inspired muffler. The seat doesn’t compromise on comfort, but the tuck and roll design locks the rider more firmly in place.
The double-seat model retains the same chassis aggression but introduces practical adaptability. A Pro Race exhaust system differentiates itself mechanically and visually, with that slash-cut muffler offering a mean rumble. The seating gives the bike a more lengthened profile and the practical capability of strapping luggage to the back of the bike. It’s a subtle balancing act, performance presence without sacrificing everyday usability. The guys also tune the suspension and make sure the entire bike operates at the highest level.
Across both versions, the component selection underscores what Classicbike-Raisch does best: integrating premium aftermarket parts into a coherent whole. Motogadget bar-end mirrors, a Rizoma fuel filler cap, blacked-out footrests and levers, and their own BMW ‘The Line’ tank badges, not decorative add-ons; they’re part of a curated system. Many of the smaller components are designed or refined in-house, reflecting the company’s dual identity as both builder and parts manufacturer.
The brothers don’t just assemble motorcycles; they ride them, hard, across Alpine passes and European circuits. The feedback loop between road, racetrack and workshop is constant. To get your own Race Cruiser, a new or used R12 can be brought to the shop, and the team works closely with the client to compile the best parts for a complete custom.
What customers receive isn’t simply a cosmetic transformation but a fully engineered Race Cruiser package, delivered street legal and ready to ride. Two configurations, one philosophy: purposeful design, executed with the precision only a family deeply embedded in the culture can achieve.
