Hi Gary,
disappointing that the later quality is poorer. Ive always fancied an ABS model but I guess that will have to wait.
My Baglux cover came 2nd hand of eBay, never seen another like it. Can be a pain if you only need to lift the tank but I like it.
Pretty sure the filter is the same dimensions on the early ST's as on the SS. Well, my K+N fitted fine from my SS. I have a spare square K+N if you want to save a few quid
Ohlins forks have been done and look lovely (pic) but no need really, I got mine rebuilt with Gold Valves and they are nearly as good, 4-pad calipers are a nice easy upgrade however, yes, I have a spare set too
