What is our front fork technology?
The new Brough Superior front suspension combines a retro appearance with an ultra-modern design. It is based on the Fior Design wishbone fork system created by French engineer Claude Fior, which was copied by BMW to create its Duolever fork equipping its four-and six-cylinder K-series models. However BMW gave credit for the design not to Claude Fior but to Zimbabwean engineer Norman Hossack, then British-based but now living in California, who raced bikes in the UK while working as a race mechanic at the McLaren Formula 1 team. That’s where in 1979 he first had the idea of adapting a racing car’s wishbone front suspension to motorcycle use, by effectively rotating it through 90 degrees. Hossack succeeded in patenting the design in 1984 (although he allowed this to expire, permitting BMW to adopt it on the K1200 unencumbered by licence or royalty agreements). Fior had already developed his wishbone front suspension design before Hossack built his first bike with such a fork. Fior had finished 8th in the 1979 Le Mans 24 Hours riding the Fior-Yamaha XS1100, with what was to become his trademark front end bolted to the stock Japanese chassis, thus transforming the handling. Fior contested several major Endurance races with a series of bikes using his own chassis built around this front end design, culminating in third place in the 1980 Austrian 1000km FIM championship on the first Fior-framed Honda racer. He later went on to build several streetbikes for Boxer Design employing the same front suspension.
