Designed in partnership with rider and engineer Fritz Egli, the turbo 900 was unveiled in the early 70s. It featured racing lines and the design was significantly more advanced than the standards of the time. The engine components had largely been overhauled, from the chromoly Hoeckle crankshaft to the Mahle pistons, Mr Turbo Ray Jay turbocharger and magnesium fork. Today it is one of the most sought-after examples of 1970s racing bikes.
