A shaft-drive super-touring motorcycle from Kawasaki's late-1970s range, pairing a touring chassis with a rubber-mounted 1089 cc four derived from the GPz1100. The Cycle Guide review praises its straight-line stability and acceleration, criticises fork compliance and high-speed handling, and rates it below the Honda Interstate and BMW R100RT as an integrated tourer.
