The 900 S was also a return of the more powerful 900ss efi engine in the monster but with carbs instead of efi of the ss as slob says top spec cast iron brakes it should also have a fully floating rear caliper too, carbon front and rear mudguards, side panels, exhaust heatshields and a lower carbon rear guard too! Not I wouldn't say rare but not so many around as normal monsters! Nice bike!
