A later-listed Z400 road-test page that reviews the same air-cooled 400 cc twin with its 1978 updates. The reviewer found it convenient and easy to use, though slow next to rivals and weak on suspension, seat and braking in the wet. The page presents the R-badged Z400 as the model name in the listing.
