The 1985 GPZ 400F-II, a naked (unfaired) version of the 399 cc air-cooled GPZ 400F engine. Its power is rated at 54 hp at 11,500 rpm, up slightly on the 1983-84 bikes, and the chassis uses the same telescopic forks, swing-arm rear and 236 mm front disc. The page gives no narrative, so the description rests on its figures.
