Premier still have a couple of Black ones - or at least they did yesterday.
Only you know if you prefer the S or the R, I found the S had very stiff suspension (compared to my 1190S) and also wondered of the R might suit me better, but I only ride on the road so don't want a 21" wheel and skinny tyres.
IMO the 1290S is better than the 1190S in every department except suspension which has gone all trendy with the Semi-Active bullshit, a bit like all the shite anti-dive systems of the 1980's someone invents something that sounds great, but does not work, and then all other manufacturers get on the bandwagon.
So I either want an S with R suspension, or an R with S wheels, and for now I will continue to enjoy my 1190S.
Tough choice matey - but you should be pretty happy with either choice.
