A later build of the air-cooled 984, still the entry point of the Vyrus range beside the four-valve 985. It keeps the double-omega frame and hub-centre steering, with a slightly higher claimed output of about 90 hp and a heavier stated weight than the early bike. Parts such as wheels and bodywork were available in carbon fibre or magnesium.
