Custom BMW K 75 RT Street Tracker Takes Pride in Its German and Italian Genetics

Craftsmen found ways to make their boxy three- and four-cylinder mills work with various custom motorcycle genres, including scramblers, trackers, and cafe racers. As long as you’re aiming to build something with futuristic or neo-retro styling rather than quintessential vintage looks, a machine like the K 75 should serve you just fine. With this in mind, Renard Speed Shop of Tallinn, Estonia knocked things out of the park in 2019.

That’s when they built the ravishing street tracker shown above, with an ex-police K 75 RT acting as their starting point. Shop boss Andres Uibomae purchased the Bavarian tourer from a local police station, and the bike had a little under 30,000 kilometers (around 18,600 miles) on the odo at that point. This meant its liquid-cooled inline-three engine was in great shape, so the guys could focus mostly on the running gear and cosmetics.

For starters, all the original bodywork components got taken out of the equation, along with the wheels, suspension, and brakes. Seeking to first address the structural side of things, Renard sourced a ton of replacement hardware from a 2008 Moto Guzzi Griso 8V. The Italian machine was kind enough to donate each and every piece of its front-end equipment to their cause.

Suspension duties are now carried out by adjustable 43 mm (1.7-inch) upside-down forks, and stopping power comes from Brembo brake calipers pinching 320 mm (12.6-inch) wave rotors. The Griso’s three-spoke alloy wheel is also present, as are its triple clamps, steering stem, and handlebar. Of course, that’s a lot of Guzzi kit right there, but you’ll find more Italian DNA at the back.

Griso 8V paraphernalia is the name of the game in this area once again, consisting of the model’s disc brake and 17-inch hoop, as well as its single-sided swingarm. The adjustable monoshock comes from the same Moto Guzzi, but it’s been repositioned horizontally by way of a custom linkage. This new suspension setup is undeniably intriguing and a testament to Renard’s extensive fabrication know-how.

Furthermore, a replacement driveshaft was required to make everything work together seamlessly, so Andres and his crew spared absolutely no expense here. They cloaked the wheels in Pirelli’s dual-purpose MT 60 RS rubber fore and aft, thus rounding out the BMW’s updated running gear. As their next port of call, Renard Speed Shop turned to the bodywork.

We now see the repurposed fuel tank of an R 80 G/S right in the center, with its underside extensively revised to fit atop the K 75 like a glove. The front fender appears to be a bespoke part, and it’s accompanied by a fresh nose fairing a bit higher up. It’s mounted right above an aftermarket headlamp and LED turn signals, all held in place via tailor-made brackets.

In the cockpit, you’ll come across a premium selection of aftermarket goodies adorning the Griso 8V’s handlebar, including Puig Hi-Tech Ascent grips and Beringer master cylinders. The switches originate from Renard’s proprietary catalog of bolt-on parts, while some off-the-shelf mirrors keep things road-legal. Behind the R 80 gas tank lies a handmade subframe, which supports curvy solo seat with plentiful padding, Alcantara upholstery, and lighter stitching for contrast.

The tail section is a custom affair, but it incorporates the last bit of Guzzi componentry we need to mention here – the Griso’s taillight. LED blinkers are attached to the tail on each flank, and a long license plate bracket hangs off its rearmost portion. Additionally, there are bespoke inner side panels located below the saddle, supposedly concealing the K 75 street tracker’s electronics.

Speaking of electrical equipment, the whole shebang was rewired via a Motogadget mo.Unit controller with Bluetooth connectivity. The Beemer’s inline-three power source may be internally unchanged, but it does benefit from some new exhaust pipework. Renard came up with a set of stainless-steel headers that run a three-into-one layout, before terminating in an SC-Project silencer on the left-hand side. Lastly, there is the motorcycle’s breathtaking colorway.

It’s a superb concoction of white, red, and blue, with the latter color also making its way onto the wheels, brake lines, and coolant hoses. Once the paint job had been taken care of, Renard Speed Shop’s 26th build was complete and ready to find a new home. It was eventually sold for a cool €25,000, which works out to just under $27,400 as per current exchange rates. That’s not cheap by any means, but we’d say the price is fully justified.
