Sorry to hear about your prang! That being said, I do love a build thread!!
Marshy has tried just about every combination of kit on RSV4, Kris too. Plenty of knowledge about.
I'd deff get crash protection, axel sliders maybe not - I find them a bit of a ball ache.
You can do quite a bit with that suspension, I'd deff get them serviced and re-sprung.
Vesrah are da nuts as far as brake pads go, Marshy can give you the exact model to suit.
Keep the updates coming!!
