context_page_description: The Hercules W-2000 was a motorcycle made by Hercules in Germany. It was the first production motorcycle with a Wankel engine.
  It was designed in the late 1960s, first shown at a German trade show in 1970, and production started in 1974. Production halted in 1977 after 1,800 were built and the tooling was sold to Norton Motors.
context_section_description: The engine was an air-cooled single-rotor Wankel designed by Sachs as a snowmobile engine, that produced 27–32 hp (20–24 kW) at 6,500 RPM. The rotor spun about the frame's longitudinal axis (see longitudinal engine for the piston-engine equivalent), with power taken to the transmission through a 90° bevel gear.
  Fuelling was originally supplied by a 32 mm Bing carburetor. An electric starter with backup kick starter was standard.
  Gasoline had to be premixed with two-stroke oil until 1976, when 199 more units were produced with automatic oil injection.
