BMW K100 Z17.2 Rebel - Custom Motorcycle

The BMW K100 custom motorcycle Z17.2 "Rebel" by Z17Customs is a Moscow-built cafe racer that bridges subtle naked minimalism with bold personalization, finished in Imola red for a Spartak Moscow fan who trusted two builders 3,000 kilometers away with his dream machine.

The Concept

Artem came to Z17Customs with a clear brief: build him a bike. He is a BMW man through and through, whether on four wheels or two. The base chosen was a 1991 BMW K100 with a one-liter engine and factory ABS. Where much of the custom scene dismisses ABS, Sergey and Mikhail understood its value: on the street, it saves lives. The K100's liquid-cooled inline-four, the first of its kind in production motorcycles, uses a shaft drive that exits from the rear. The result is a low center of gravity, smooth power delivery, and near-zero mechanical maintenance.

The Build

Stripping the original fairings and heavy components brought immediate weight savings to the once-portly K100. The rear end was entirely replaced with a cafe tail, molded and fabricated with an internal steel structure for rigidity. An integrated LED strip handles both indicators and stop light in a single flush unit, eliminating all visual clutter. The seat was made and upholstered in-house. Up front, a new headlight was fitted alongside an all-in-one speedometer, while the remaining controls were left stock to preserve the K100's clean ergonomics. A single stainless steel exhaust was installed to release the character of the inline-four that the original muffler had suppressed for decades.

What Makes It

The color scheme is the Rebel's defining statement. Bright Imola red with white stripes, the palette of Spartak Moscow Football Club, chosen by a client who wanted his personality on the tank. The combination of the cafe racer tail, the shaft-drive architecture, and the bespoke color treatment results in a machine that stands apart from the sea of monochrome customs. It is aggressive where it needs to be and restrained everywhere else.
