BMW ‘Alpha’ by Mark Atkinson and Mehmet Doruk Erdem

Born from a concept by Turkish designer Mehmet Doruk Erdem, the BMW Alpha provides a glimpse into the future of motorcycles. The bike, which was inspired by the Great White shark, was then designed specifically for the Bonneville Salt Flats and going after the land speed record.


After getting wind of Erdem’s design concept, Mark Atkinson decided to build the otherworldly machine, from scratch. Upon reaching out to Erdem, the two then worked together in order to finalize the details of the motorcycle, as the finished product is pretty damn close to the Turkish designer’s original renderings.


The aforementioned donor bike is a BMW K75S equipped with a horizontally mounted triple that produces roughly 60-horsepower. The chassis is completely custom, essentially an aluminum cradle that wraps the K75s engine. Because of how low Alpha is the bike needed an unconventional approach to attach the front wheel and steering assembly to the chassis. Mark opted for hydraulic hub steering mounted to a swing arm. Continuing with the theme thus far, Mark built the entire steering assembly himself, taking a rear drum brake from a vintage Suzuki motorcycle and fabbing up a unique linkage inside. Now you won’t find any suspension under here, instead what you will find is that the custom swing arm is attached to an actuator to raise and lower the front of the bike, bringing the body off the sliders that the body rests on and allowing it enough clearance to actually ride.
