The RS-Z (also sold as the RS-D or Deluxe) was the later, better-equipped CB250RS. Its main change was electric starting in place of the kick-only arrangement, along with different paintwork and a lockable seat hump. The four-valve balanced single, chassis and brakes carried over from the standard RS.
