“Hurricane”: BMW Flying Brick Café Racer

The BMW K100 “Flying Brick” represented a significant design leap for BMW Motorrad, who’d long been known for their flat-twin “airhead” engine design. The K100, in contrast, was a fuel-injected, liquid-cooled inline four laid flat in the frame — a design that benefited from the company’s deep expertise in building fuel-injected, overhead cam automobile engines. The K100 engine offered serious punch for the era — 95 horsepower — capable of pushing the 537-lb sport tourer to 137 mph.

Enter Paul Fill of @Kustom_Moto. an experienced track rider who turned to bike-building after a serious injury put an end to his track days some half a decade ago. Previously, we featured Paul’s Yamaha XS650 brat / tracker and BMW K100 street scrambler. Not a man to sit on his laurels, Paul is back with the “Hurricane” — a BMW K100 cafe racer loaded with tons of trick parts. Below, we get the full story on the build.
