The CB650SC (also called the Nighthawk 650) is a Honda standard motorcycle sold in the US from 1982 to 1985.
In 1982, the Nighthawk replaced the Custom of the previous years and featured a re-designed tank and side covers. In 1983-1985 a new DOHC engine replaced the SOHC engine used from 1979 to 1982. The new engine had hydraulic valve lash adjusters and was rubber mounted. This year also saw the move from chain drive to shaft-drive for this model.
