Bloody hell Gary an SPS owner..were not worthy !!
(I think your the first on here).
Think the lads have covered most of the other points but ref; brakes its surprising the difference pad material can make...Carbone Lorraine (SBK3?) pads are the best way to go for the cast iron brembo discs you have I am told and make a shed load of difference (yet to fit them with mine)
I also think the brake master cylinder on the SP4 is the same (unadjustable) one as the strada which I was very disappointed with when I bought my bike...change it for a 19x18 brembo radial master cylinder..not only do they look the borrocks..but will improve things no end due to its bigger piston and span adjustable lever.
Congrats on a fine purchase..look foprward to swapping takes of 888 ownership over the coming months..!
