A faired ZRX 1200S from the 2004 to 2005 model years, using the same 1165 cc transverse four and chassis as the other S versions. The page highlights a larger half-fairing, a twin-beam headlight, wide-set mirrors and a revised dashboard with temperature and fuel gauges. The reviewer found its handling and performance close to the R despite the extra weight, and noted that the 19-litre tank gave limited range.
