yeah only 900 and s4 came out in the cromo guise
the s4 being a smaller run than the 900
Things of note do not drop as i did (replacement tank is 2k) and was only one left which i had for the s4 dont know about the
the origanal cromo came with black body work and silver belt covers which are indeed all carbon fibre, having had ray and rosso course looks mine and there is lots of little special details on the s4 cromo its basiclly and uprated version on the standard s4
I love mine in sure you will love yours
